Unfortunately I haven’t even had a chance to shoot mine.... bullets,brass, barrel and action all just sitting. Hopefully my stock will be in at the end of this month
Thanks for those replies. I figured you had people who already want to size the brass to sell. Thus, in a pinch, the SAUM is the preferred brass to work with, then how hard would it be to size down and fireform WSM?
JLK used to make some great 108 gr. bullets. That was as much as a 1-10" twist could handle.
The PRC is a magnum boltface. It's just slightly smaller than the WSM's. And a smidge longer than the SAUM.
What I’d like is a .257 Roberts thread with Blackjack bullets! Of course, the Ackley fans would have to be allowed in as they are one of the most popular wildcats of all time.
The 131’s are still mia from late 2020. Many have transitioned to the 135 berger. Ive got plenty of both but have been shooting the 135. The 133 berger hit the shelves recently as well. Graf’s has large and small primer 25 cm brass in stock. Last I checked Blackjack was pretty slim on reamers. You can download the prints there to see the specs.
Yeah, I’ve had 2 boxes in order since Jan 2021…. But the Berger 135’s can still be found, and I’ve shot Berger almost exclusively for 10 years. I still have a few loads that use Noslers, but the rest are Berger.
Because Berger wouldn't have done shit if Blackjack hadn't opened the door.
To add to a Coldbore said, the 131 technically is a higher performance bullet. It’s got a higher BC and can be pushed faster. I found that the 135s pressure up more than the extra four grains of weight suggests it should. They’re about 75 ft./s slower in my gun on the 131’s Additionally, a lot of people are heavily invested in the blackjack bullet. Blackjack is a nice company to deal with and it’s really unfortunate that Sierra has them over a barrel right now. sierra would rather sell ammo and bullets at pandemic pricing, then honor standing orders from before all this bullshit started.
Same could be said for a lot of things.
I’ve found the contrary. 135s, at least with the proper chamber, can be pushed to pretty much the same speeds as the 131s without pressure, and I sure as shit don’t see any appreciable BC difference between the two. Maybe I’m just one of the lucky ones.
I made a very similar comment on a different discussion when the 135s were first announced. Don't get me wrong, I'm very happy Berger produced the 135s and the 133s, but Blackjack was the first that had high BC quarter bore bullets brought to the market for mass consumption and made others realize there's a profitable market for 25 caliber bullets that aren't just hunting bullets.
I've got a 7 twist, 25" 25Creed barrel on the way for my M7 Mausingfield, and when my 6x284 is toast...That's going to become a 25-284
Nobody knows what's going on at blackjack currently......they've gone pretty quiet. One the founding partners publicly split from company due to unknowns, but i feel its the ethics of taking peoples money and not giving a delivered product for over a year. Sierra has put this company in a huge bind. Dtac too, but Tubb likely has money in the bank due to many more years of operation.
Tubb just put out an email saying dtacs are inbound. Perhaps thats a sign that sierra is getting their shit together.
Which one split? Was it Myles or Logan?
I've noticed some 107 and 142s in stock as of late, so they are actually making bullets. Seemed as if they went under too. Perhaps they made a few hundred million rounds for the gov to fight the imminent civil war thats coming.
correct
Im using the BJ Rev 2 reamer, which has .115 freebore and a .290 neck. Loaded neck dia in lapua 6.5 brass measures .2845, and annealed/fired cases measure .2885. I think they designed this for “thick” necks, but its ideal imo.
*131 Blackjack I believe
