25sst finally breaking it in

[crystalgayleguy]

I went with a 25-284 for shooting the 131 BJ bullets. Couldn't be happier but, one of my first initial choices was the SST. Maybe next time. LOL.

what velocities are you getting with 25 284

What are your COAL's with the 25-284 and the Blackjack bullets?

Barrel is inbound. Sounds like Axisworks will be doing mine and Lance's around the same time.

5 shots today at 61.4 of 565
3247 velocity with es 5.3 and sd of 2.7
hopefully get a chance to shoot groups @ 400 this weekend

For those of you with more experience, is that node size standard? A spot that flat for almost a grain difference seems rare, from the data I've seen.

 

[rockwallraider]

i've never seen it before
went back today with 61.4 and it was in that same space again. i shot the 6.5ss with a really good node spot and it shot 15 ft/sec faster today. who knows. hot as heck here in dallas

What kind of chronograph you using?

What are your COAL's with the 25-284 and the Blackjack bullets?

This is the honest truth...The base of the bullet sits halfway down the shoulder of the case and it cycles perfectly out of a REM 700LA. In other words, I have never measured the COAL. Honestly!
