131 BlackJack bullets will be shipping next week.

[lee31]

For all the guys that were wondering about the .257 131 grain blackjack bullets. They will start shipping next week. The people at Blackjack are standup guys and I'm hoping they do well. They had some delays but that's to be expected for a new company that has sub contractors. They got their first shipment from Sierra today and are expecting another 250,000 or so bullets shortly. Hopefully I'll have my bullets by the end of next week. This is exactly what us quarterbore guys have been wanting. By the looks of it they look to be pretty dang accurate too.

1:7 for most cartridges.

Any estimate on speed and trajectory out of a bee?

They hit 3150 safely with a 25-284. So I'd say 3300 plus.

I have a 1:7.5 at my buddies right now. He said he'll have it done for me in a week or two. Has a couple other projects ahead of mine

131 @ 3300 would be a cool ride

Well my bullets arrived today. I checked weights and base to ogive on 30 bullets. 29 of the bullets were right at 131 grains and one at 130.9. Base to ogive was identical on all 30. I'd say these bullets are top notch when it comes to consistenty. They are also very long and sleek.
Pictured next to a .257 115 Berger and a 6.5mm 140 VLD Hunting Berger. The 131 is RIGHT of the 140 Berger. Also a pic of the 115 Berger and 131 ace seated to the same measurement to the ogive. My buddy should have my rifle done on the 13th. As soon as he's done I will be some testing.

Really looks like it would be on the right of the Berger 140.


What a missile
