131 Blackjack

[Dug]

My my, I mentioned wanting good .257 bullets & a 25 Souper on this site in June 2017 & nearly got rotten tomatoes thrown at me.
What a dif a couple years & a bullet with numbers like this can change things.

Thanks Blackjack!

Being that Proof is a cut rifled manufacturer they should have the ability to cut any twist a person may want.

Josh,
Did you get a barrel for the .257 caliber ? I just ordered one from Bartlein. CFW M24 contour 7.5 twist to finish at 24". Chambered in 25-284. It's a next summer finish project but look forward to the finished product.

I have not. Would be fun but too many irons in fire right now.

What twist is optimal? Would a 1-7.5” work in a .257 Weatherby?

These bullets are making me want to chamber a .257 Weatherby.

They sure will, so will a 8 twist..

Call Proof first before getting your heart set on a non-standard twist rate. They pick and choose which twists they will sell. I've not read that offer any and all twist rates.

Ya me too but What the Heck. Got so many now I can't get the load development done on most as it is.

Bartlein will do any twist you ask for.

Currently waiting on a Bartlein CFW barrel in .257/7.5 twist/M24 Contour. It's moving along quickly. Should see it fairly soon

I was on the phone with Brux ordering a 30" MTU (fluted) for
that SA284 of mine. I have a spare Savage target action that
needs company. I was told there is a reamer for the 284 Win,
necked down to .257. And I say, Hmmnnnnnnn !! Maybe a
SA257 in my future and call Bartlein for one of their longer life
barrels.......Always thinking out loud !!

I heard your thoughts ! My original build was gonna be a 6.5-284 for a lightweight Pronghorn hunting rifle. Once I saw the 131s come out, it changed my thought on that rifle. Less recoil, better LR ballistics. Probably a bit less energy on target at the longest ranges but much less drop with the 131s. Wanted it in a SA and your SA257 would do that. So would the .257 Blackjack (SAUM) case. I just like the 25-284 case so it'll be on a LA. Used for deer with Speer 120SBTs, I'll make it a lightweight whitetail rifle for woods carry at shorter ranges as well. I'm not really expecting many future .257 LR bullet options to become available. It's one of those calibers that just won't catch on. Having one good LR option is good enough with the few others out there for mid range shooting.

Can anybody give me a site to purchase the 131s ? I tried the Blackjack site but it won't let me order. I don't think that site is active for ordering. Thanks

Call them. Website is having issues with PayPal. They currently only have the XL (run with 0.020-0.030” longer bearing surface) bullets in stock but hopefully the next shipment will be in soon.

Thanks. Found a member that had a box of 500 for sale. Interesting tho on that longer bearing surface bullet

Anybody have a set of 25-284 dies they want to part with ??? Looking for a reamer also. Thanks.

Might just as well contact Blackjack. They should have everything you
need.

Ya I've been trying. No response and no return contact after leaving messages. I'll keep trying.

I would think a bushing set of 6.5-284 dies would work with appropriate bushing and the 6.5 seater should work with the 131 also.

My plans for a 25 creedmoor will include my current 6.5 creedmoor dies which should work perfectly.

 

[std7mag]

Would the larger seating die possibly cause some excessive runout?

Seems like a lot of wiggle room when using a 6.5 to seat a .257

 

[8andbait]

In theory it would but I’ve heard nothing but good things about using a 6.5 seater. Most even use the 6.5 stem and it sits fine on the ogive.
