Does anyone on here do a lot of shooting with 6mm CM? I just bought a Savage 110 Tactical in 6mm CM and am waiting for it to arrive. I also got three boxes of Hornady ammo in 80, 103 and 108 grain flavors. I am hoping that it likes one of the three I bought, but if it doesn't, since all brass is Hornady I can use it to reload.

So if anyone has a Savage rifle in this caliber, or any brand really, what are your thoughts?

Just here for the info. I am very interested in that cartridge.

My goal is to find the best texas deer rifle I can find with as little recoil as possible. RIght now that is a .243 but as I understand it the 6mm Creed has even less recoil even with slightly heavier bullets.

I am also interested in this thread. For the reason stated above.

6mm is the bullet of choice for competitive shooters for a reason. Although most shoot BR variants, the Creed is not much different. Soft recoil and flat shooting. My 6 Dasher is under 1/2MOA with 105 Bergers. I've killed a few pigs with it DRT. I love the 6's and made another for my varmint gun. Only reason I didn't go Creed was bc it is a little hotter than the BRs so barrel life is less. But you are still getting 1500 rounds per barrel. Definitely recommend.

I know it's not hunting related but good write up on PRS calibers. 6 creed is top 5.

Short answer, they work, and factory Hornady ELDX or ELDM are the easy button. My next barrel will be either a 6 Creedmoor or 6 GT.

My next rifle purchase will be a 6mm CM. The ballistics for that round are impressive. I will designate it as the cull gun. No advice on bullet selection. I am hoping that the heavier end of the spectrum performs well.
Honestly every barrel is just slightly different. Find what shoots the best out of your rifle regardless of projectile and roll with it. Accurately placed neck shots will drop deer after deer with no tracking needed.

I have a 6cm ar10 I built and love it. Have hunted a bunch with it over the last few years.

Why would you get something that is the exact same as a 243 win but has way less history and nowhere near as much ammo. 6 cm is just trendy and will be gone soon.

It's a carry over from competition shooting. Throw a heavier 6mm bullet in a 6.5 creedmor case you get 25% more powder than a Dasher.

When comparing the 243 - Faster Twist barrel and shorter case with the ability to shoot larger grain and higher BC bullets. Factory loads with 115 grain bullets.

243- 1:10 twist
6 creed- 1:7.5 twist.

Can stablize a lot larger bullet. 243 with 1:10 twist can stabilize 95 well but max 100 grain. Now you do a 1/8 twist 243 they are the same. You could get a 115grain on the 1:7.5 twist creeds

I know 243 has been around forever. I have killed a dozen deer with one.

But if it was perfect competitive shooters would be using that and not 6 creed.

6.5 Grendel is excellent for what you describe. In Ar15 platform it will be the softest recoiling/most capable. Good for anything in North America (except the big bears) at any ethical hunting distance and all the African plains game.

Sorry to derail. I do not participate in these trends. As expressed above 243 over 6 creedmore.

Suppress a fat barreled .308 Win. This is not sound advice for 350+ yard shots.

But the .243 doesn't have any recoil.

By all means buy another rifle but if you're wanting to kill deer out to 300 yards then save yourself the trouble and go with a .243.

It kills caribou and elk. And it's as accurate as the fanboy 6mm Creedmoor out to most "reasonable" ranges.

Or, buy a .270

Or .308

Or .30/06

Or 7 mm Mag

What's funny is 6.5 Grendel is only 6 years newer than the 6mm Creed. 2003 built off 220 Russian. Origination of 6mm Creed is obviously in its name built in 2009. Both are great at their individual purposes. 6.5 Grendel for an AR15 and 6 creed for AR10.

Wish there was more Grendel ammo on the shelf. I see more 6mm ARC than the Grendel.

You can pretty much say the same for almost any new cartridge developed: something else invented 50+ years ago already covers the same purpose. Technically, you could just buy a .30-06 and be done with any and all centerfire hunting needs for anything in North America.

But what's the fun in that?


I love the .243 and have a soft spot for the cartridge since my first deer rifle my dad gave me for Christmas is in .243. (Cue the Whiskey Myers song). But 6 Creed is superior to .243 in several ways. It has better case design in that it duplicates .243 velocities but allows greater flexibility in bullet selection favoring the longer, higher BC new 6mm bullets while still working within typical 2.8" mag box constraints. If you reload, you can take advantage of the Creed's case and use the longest, heaviest bullets, that will still fit in the mag box without consuming too much powder space due to having to seat them too deep in the case neck. 6 Creed rifles are twisted correctly from the factory to handle these new high BC bullets @ 1:7.5. .243 rifles with few exceptions typically have 1:10 twist barrels so they don't stabilize the new longer heavier bullets well. If we look back in history, .243 basically killed Remington's 6mm Rem because .243 was twisted 1:10 and the 6mm when introduced was twisted 1:12, meaning the latter wouldn't shoot bullets over 80 grains well. Now the 6 Creed has one-upped .243 in the same way.

Currently 6 Creed is outselling .243 and so far its future looks bright because Hornady supports annd promotes its new cartridges well. Will it remain commercially viable over time? Who knows. Everyone said the same about 6.5 Creed, abd yet it is now the second highest selling CF rifle round behind .223 /5.56, with no signs of slowing down.

If you don't reload, the current factory ammo selection in 6 Creed is superior to .243, with better bullet selection used, and far better likelihood of superior accuracy due to exceptional bullets and the correct barrel twist to shoot them.

So, if you have neither already and you're looking for a rifle in 6mm, there's no real downside to selecting 6 Creed over .243 given todays bullet technology and current rifle offerings with modern faster barrel twist.

Have a 6 and it is a heat seeking missle. I swear I dont have to even aim that thing and my animals drop. Switch out varmint guns to it a few years ago. We got tired of having stuff run off with a 22-250,223 cartridge. And out to 300 yards we dont have to worry about much drop. Killed many mule deer and audad with them. My favorite gun in the safe.

My dad taught me that it's all about proper shot placement.
Having discussions on how good certain cartridges kill is akin to what fishin lure is the best.
Everybody has an opinion and all can be the correct one.

My comment was /s.

This is the same dumb crap from the 300 WM vs PRC thread.

I shoot 109 Bergers out of a comp 6GT and a NRLH Factory 6CM.

Will likely be taking the 6CM elk and bear hunting in a month.

Haha I know. This board is funny.

Why is it "dumb crap?" Improvements in bullet design drives improvements in cartridges and the firearms manufacturers respond with faster twists. Most hunters will ever need the long range potential the higher BC bullets can offer, but the side benefit is they are more uniform in balance and mass so they provide superior precision when used with the right barrel twists which has benefits at short range too. Also, a longer bullet of greater mass for a given caliber penetrates better, all else being equal. Small, incremental improvements over legacy cartridges are still improvements, and if you don't already have a rifle in one of the kegacy chsmberings, what's the downside to buying a slightly better mousetrap?

Guys 50 years ago were asking why anyone would buy a .300 mag when their .30-30 would kill a deer.

I'm not 100% sure on if we are agreeing or disagreeing.

But with guns in my safe currently I picked:
22GT over 22-250
6GT over .243 win
6CM over .243 win
6.5CM over .260rem
7 PRC over 7RM
300 PRC over 300WM
33XC over .338 Lap


Because they all do things at least incrementally better than the legacy cartridges.

Your sarcasm was missed by most

I have a .260 rem, but I bought it in 2012 before the 6.5 Creed got popular.

I have thought about that. I may just get an upper in 6.5 grendel and give that a shot. I have plenty of lower receivers that will work with it.

6.5G is my favorite sporting AR round. I have not shot them all. But, it does everything I need. This past weekend I did a little break in of my newest 6.5G. A 2 stamper.

What kind of velocities are you getting out of it? SBR grendel would be fun.

don't know. but i have a Q Jumbo Shrimp on the end of it. with the LaRue stock fully extended, it's a 1/2 inch shorter than my brother's Colt 6940. It is quite handy.

the one thing I have not yet figured out is the optic. currently it has an old scope on it that I had laying around.

If we look back in history, .243 basically killed Remington's 6mm Rem because .243 was twisted 1:10 and the 6mm when introduced was twisted 1:12, meaning the latter wouldn't shoot bullets over 80 grains well. Now the 6 Creed has one-upped .243 in the same way.

I was a bit confused by this statement. But to be clear, I'd assume you're referring to the .244 Remington developed as more of a lighter varmint round, with the 1:12 twist?

The 6mm Remington was first used to describe the 1:9 twist version, designed for "big game."

And I think it's superior to the 6MM cm (and certainly to a .243), but I've been hunting with a 6mm Remington almost 30 years and may be biased.

Yes, you're right, when Rem renamed the .244 as 6mm Rem, they did change the twist to 1:9. However by then the damage was already done because Rem originally envisioned it more as a varmint cartridge favoring lighter bullets whereas Win promoted the .243 as a dual purpose round with up to 100 gr bullets for deer. The .244 and .243 were introduced the same year. It took Remington years to finally correct their marketing and twist rate mistake and by then .243 was already well established as the better choice for deer. Although 6mm R is a little faster, ultimately .243 still wins out because Remington selected 7x57 as its parent case, which is really too long for short actions if you expect to take advantage of the heaviest bullets for big game. If you load the heavier, longer midern bullets of today, any velocity advantage it offers over .243 is eliminated by the fact you have to seat the bullet way too deep to fit in short action mag boxes, consuming powder space.

6 Creed further improves on .243 in the same ways if you intend to use the modern longer sleeker bullets.

Lots of information in this post, thanks to all. I was really only wanting bullet info on the 6mm but I do like the back and forth banter.

I pick my new rifle up this evening but will not be able to shoot it for a week or so, but I am looking forward to seeing if the three types of ammo are good in it or if I will need to reload, which is always fun.

If anyone has any bullet info that shoots well for them, please post it. I only have Hornady ammo right now but may expand if I find some different out there. I would like to shoot Remington Core-lokt tipped, but I have never had that, or regular Core-lokt shoot well in any of my rifles. Maybe it will in this one. I am looking forward to breaking it in and getting it zeroed here shortly.

In my Seekins, 109 LRHT over 39.4 H4350, Lapua SRP with BR4s shoots a 20 shot group at .7" with a single digit SD at ~2960 FPS.

I'm going to hunt with the factory Hornady 108 eldm ammo because it's good enough.

After hunting/comp season I'm going to try the 115 DTACs.

Do you texags much? You should have led with that. I mean it wouldn't have worked either, but then at least you could have said you tried!

If you reload... 30.8gr CFE223 under a 129gr ABLR is producing hole on hole results at 2400FPS and per strelock should open up all the way out to 800yds
