6.5 Creedmoor Wildcat

[RustyPin]

There is a new 131 Grain .25 Caliber Bullet release. It's called Black Jack? 655 bc? This really lends itself to the Bob & 25-06. 3000 fps is expected from the Creedmoor Case.

It really isn't a 6.5 Creedmoor wildcat. The Creedmoor itself is a wildcat made from a 30 TC.

 

[RustyPin]

It's not really a 6.5mm, since it's not really big stuff, it's only a quarter bore. I just thought this would be the best Forum. The post is really about the Bullet. "131 gr 0.257" ACE bullet (0.330 G7 / 0.645 G1)". True about the TC, just nobody cares about the TC. Anyone with a Large Case Quarter Bore Rifle might be interested.

Shot my very first big game animal as a child with a Browning lever action 257 Roberts. Always kind of like the quarters, but nobody every made good LR bullets for them. Good to hear someone is finally stepping up and giving a good LR offering.

I have always liked the 25 cal as well. In the last 6 months I brought on line a 25 Norma Dasher and it does shoot well at 400. There is an accuracy node at 2950 fps with a BIB 110. I have gotten a little over 3000fps with the 110 and 115, but not enough room to get to the next node. The 115 Berger has given me some 1 inch 3 shot groups at 400 but I haven't worked with it that much. This is with a 9 twist Krieger barrel.

I have a 25X47L being chambered as we speak. The reamer is one to my likings with some input from Randy Robinett. If it shoots as well as the Dasher with a little more speed, I'll be a happy camper.

They have advertised the bullets for a while on this site. I'm still waiting for some independent testing.

Agreed.
I’ve been trying to make a .257 AI shoot better than “respectable” for around 10 years (I know, I’m slow) with the 100 SMK and 115 Bergers. The occasional .75” 3 shot group at 300 will get me all worked up only to be followed by groups of 1.75”-2.0”. I must admit I’m tempted to get a cut rifled barrel in .257 and trying them myself.

Looks like a one-trick pony with the required barrel twist.

Almost identical to the CM case is the 250 Sav AI except in the 30 degree shoulder version. I've two 250 Sav AI's and I think 3000fps with a 130 gr is really pushing it. IF I was determined, I would look to the small primer case for an extra margin of strength . . . but I am not so inclined

I'd assume you'd have to purchase enough Bullets for the Life of the Barrel, or at least 1000-3000. Roughly 16.6 percent increase in capacity over the Creed. Guessing 3100 Node?

I’ve not researched the velocity possibilities, but I suspect you may be correct.

Now if you went with the Modern Proven 6XC Brass it would make this more Plausible. So, If you purchase 22-250 Lapua Brass and then Fire Form it how is this better than the 25-Creedmoor? Keeping in mind 6XC is +- 3 Grains less Capacity than the Creedmoor.

My comment was not offered as the proven solution but simply a suggestion: if I were trying to get 3000+fps with 130gr bullets out of 25 cal wildcat based on a 6.5 CM case, "I" would go with the strongest case possible which would be the new Lapua small primer CM case. I don't know if it's worth the effort - that's for you to determine. Having said that, I hope you keep us informed with your progress.

I would love to see someone offer a production rifle with a formal, standardized 25 CM having a twist between 8" & 9" if for no other reason than: (1) we'd see new bullets developed and more choices for us who hand-load and (2), the major cut-rifled barrel makers would probably start making 25 cal barrels with similar twists. Anything less than a 10tw now is a special order and takes forever to get

I agree, I think it's 7 Twist though. Yea, I'm not taking the Plunge just yet either.

My 25.06 shoots great with 110 gr Accubonds. I'd heard about the Black Jack bullets, but, I'm not going to go out and get some. One of these days I'll bump into some and that will be enough.

And who is going to make the jackets for these heavier bullets?

The bullets are made for Blackjack by Sierra.

The guys at Blackjack Bullets have a good selection of 7”, 7.5” and some 8” twists on hand from multiple manufacturers in multiple contours.

Having always wanted (tho not needed on my usually hunting grounds) a nice custom in 257 WBY Mag I can visualize it being set up for a bullet like this. Much more so than a wildcat on the 30TC case (which was "wildcatted from some other case).

I dunno why everyone try's to be smart about the 30 TC case, the Creedmoor has very different dimensions than the TC. It has a narrower Shoulder & a Shorter Shoulder. It's not the Same Case. You can make the Creedmoor out of an Awful Lot of Donor Brass. Tell you what, If I said .25-30TC Wildcat now that would be a totally different Cartridge than the .25 Creedmoor. The .25-30TC cartridge would pretty tall and might even rival the height of a 08 Case. It would also Cost Twice as Much and would not offer the Availability benefits of the Creedmoor. Like I stated earlier, it's about the .25 Caliber High BC Bullets.

I was working for TCA when the 30TC hit the street. I know about it very well. It was actually marketed to do something it never really did well enough to make it popular and it, along with the Icon rifle, failed. Sad for the rifle; I own one of the few Icon Precision Hunters ever built in 6.5 Creedmoor and it is one helluva shooter.
As for the 6.5 Creedmoor, it did spring up from the 30TC. If you need more proof just ask Dennis Demille at Creedmoor Sports or call Hornady Tech Support. The dimensions are slightly different, that's true, but so are the 260 Remington compared to the 308 Win. looking at them side by side the only real difference is shoulder and neck. Case body is the same.
Oh, it is about the quarter bore bullets of high BC and that is why I replied that I would love to utilize them in the front end of a 257 WBY.
