In a 300 rum rem 700 factory barrel..... will they make it or make the old "blue fog" coming out of the barrel..
berger accuracy no problems however they claim the j4's hold up to around 3500 fps, just wondering if anyone has pushed um that high "without blowing up" [img]/ubbthreads/images/graemlins/blush.gif[/img]

I don't know where the 3500 FPS came from, however I don't believe you can break it down into something that black and white. I wish it were this simple. You have to take into account the twist rate and the cartridge, the overall RPM's the bullet will be spinning at, and any rough spots in the bore, things like this that can make any bullet blow up.
We have spent a lot of time and money digging into the reason bullets blow up and have found that there is not one single thing that all the sudden makes your bullet blow up, it could be from a combination of things at once, or just one thing.
Hope this helps.
I want to thank all the long-range hunters for trying our NEW Hunting Bullets.
