new 257 caliber bullet

[yorketransport]

I'm almost ashamed to admit it, but I'm actually intrigued by this one.

A 131gr .257 bullet doesn't offer any practical advantage over 115gr 6mm or 147gr eld-M 6.5mm, but it's just different enough to be interesting.

Maybe it will take off and eventually relieve some pressure on the 6 mm supplies.

It could be a pretty good thing if more companies join.

If you get that fast twist 1/4 bore don’t forget about the 128gr hammer hunters

I was watching this thread and then forgot about it.

haven't messed with , very happy with the 115 bergers in mine...

Wish I had a faster twist barrel... 1:10 won't shoot these as near as I can tell.

Blackjack is selling 7.5 tw blanks I think. Or at least pre ordering them on their site with the bullets

[jackelope]

Ya 7.5-8 twist barrels.

I always error on the fast side for twist. Very little cons and plenty of pros going faster

[yorketransport]

My first thought was to pick up a 1-7" twist barrel from Blackjack and see how fast I could get one of those bullets moving. Looks like they're a little worried about how well the bullet will hold up above about 330,000 rpm though.

I may need to drop to a 1-8' twist, but I think I've got an idea what to do with these.....

I see that Blackjack place has a pretty big 48hr sale on their .25 cal Lilja barrels but if you're interested in one you may not want to wait because it ends July 5th at midnight. https://blackjackbullets.com/product-category/barrel-blanks/lilja-barrel-blanks/?v=7516fd43adaa

I have to give those guys a ton of credit for going all in on this. Setting it up so that you can get bullets as well as appropriate barrels and reamers from one vendor was a great move.

Interesting enough, I ordered a box of the 131’s.
