Home Forums Hunting & Shooting Hunting Rifles Score! Ruger American Predator 6mm Creedmoor.

Looks like just another .243 to me. What's the big deal? powdr

Better twist rate than any .243 that's commercially made and will handle pretty much any bullet you can put in it. Since manufacturers won't update the twist on the .243 Win rifles to handle heavy bullets, then why not bring out a cartridge that'll force them to use a faster twist barrel? Even if it is very close to the .243 Win.

Not entirely true. My new No.1 Varmint is a 1-7.7". Now that Ruger is making the faster barrels, perhaps they'll offer them on more stuff.

I would actually have preferred the Creedmoor round for its possibly better barrel life, but I'll deal with that issue after 1000-1200 rounds or so, so possibly never.

Well, part of it could be that we're also taking the standard 308-length stuff and exceeding common short action mag boxes and throats, with these new long-for-caliber pills....I've been guilty of it in 358, since NABs came out. Same in 223-length.....twist is just one issue, it seems. It's almost like the majors should just twist a long action right, and get them to feed short action calibers.....or we could just go back to long action calibers? LOL

My responses on another thread did point me here, and the 6C pres is interesting me, for efficiency.

Bet you wouldn't have a 1-7.7 twist on your new #1 if Ruger hadn't come out with the 6mm Creed..

Hit the range real quick today. I loaded up some Nosler 6mm, 105gr RDF's. Started on the lands and loaded them in sets of three. Backing off in .020 increments.

These two groups were the last two I shot at 100 yards. The further I backed off the tighter they grouped

2.740 left, 2.760 right. 2.740 was my last set. I'll load two more sets of three up and seat them at 2.730 and at 2.720 and see if they tighten up anymore.

Keep buying .243's. Nobody is twisting your arm to buy a 6mm CM. It's basically just a 6mm-250 with a blown out case. But I like it and also have one of these American Predators in the cartridge. Hornady's factory 108 Gr. ELD ammo at $24/box appeals to me if I don't want to reload. I didn't see any 108 Gr. ELD 243 ammo out of the 51 products Grafs lists....or anything over 100 Grs for that matter.

How much doe it weigh?

They make the standard American in 6mm CM w/ 7.7" twist?

Pretty awesome results here!

Pretty good for any factory rifle! Guys spend a heck of a lot more on rifles that won't come close to that.

22" inch mid weight barrel 6.6lbs. The barrel is slightly heavier than a sporter weight.

The standard American isn't listed in 6mm CM, but I'm sure it's on the way.

No doubt, but since they've got the mandrels now, the cat's out of the bag, and more may follow. I'd like to see the CR in a Hawkeye Predator.

Well I hit the range again today starting were I left off yesterday. My last load yesterday had shot well at a coal of 2.740. The 105gr Nosler RDF shot tighter the further I backed off the lands.

I shot three sets of three today. (3) 2.740 (3) 2.730 (3) 2.720

The rifle really likes the seating depth of 2.740 with the RL-17. I'm going to load a bunch of the 2.740 loads and go to the 300 yard line tomorrow.

I also gave the 87gr V-max a try.

Then comes the heart breaker❤️!! I was hoping that the new Sierra 110gr MK would shoot in this rifle with the 1-7.7 twist. I have ran them through the paces just like I have the Nosler 105gr RDF.

With the Sierra 110gr Match King. I have tried the gauntlet of seating depths, with both RL-17 and H4350.

Bellow is the best the 110gr Sierra MK's have grouped out of this rifle.😬 they just won't shoot so far.


87gr V-Max top

110 MK bottom

I also gave the 105gr Nosler RDF's a try with H4350. I started at 2.780 and backed off in .020 increments. With H4350 the 105gr RDF''s opened up the further I backed off the lands.

Thanks for the updates on load development for the new rifle. Helluva shooter and your're making it hard for me to resist one.

So Heaven, you're saying that 8grains of bullet makes the CM a real killer. Haven't needed it in the last 40 years. Let's see...I'm going to trade in or sell my .243 that shoots 100gr bullets just fine for one that will shoot a bullet 8grains heavier. Doesn't make any sense to me and while I'm thinking about it 257...GFY! That's twice now you've been a smart ass and tried to belittle me in front of the fire. Won't work trying to intimidate me. powdr

Ummm.

These Creedmoor rounds are where it's at. At least that's what my son keeps telling me.

With the 243 being around almost as long as I have...

and been doing a fine job...

I am seeing no reason to get rid of them and go get one of these...

and for fast twist.. I have a 6mm Rem on a Long Action, and is throated for mag length loaded rounds...

guess everyone feels the need to reinvent the wheel...

Normally I'd agree with you but now I have no choice but to embrace the Creedmoor. My son is frustrated that I'm hesitant to jump on the Creedmoor bandwagon so he says he is buying me one.
