Thread: The next flop?

The case design could be an innovation in the market if applied to cartridges more useful than a 7mm magnum style. Lots of questions to be answered about practical use. Could be interesting in concept.

Yep imagine if we could fill a 7.62x39 base (6.5 Grendel,6 arc) case up with fast pistol powder to sky rocket the pressures and get a 130-140gn doing 6.5 creedmoor velocities or better

Could make for some mighty compact rifles (howa mini size action for example )that will match much bigger rigs that use the older technology
The case technology is certainly very interesting
Watch this space

You can do that with a 22" barrel now. So not a huge gain. My 74 Targex are 2970 fps from a 20". Or are you thinking 3k from a 16" barrel?

Your 74s might be doing 3k from 13 or 14 at 80000psi!

Yuck keep your extra inchs to yourself!

I do 2850 in an 18" now its plenty but a little more is always nice or the same but shorter.

GRT suggests 80kpsi would give 2950ish in a 16" with my same powder and bullet. Thats what I mean as well as higher pressure helps a more complete burn with slower powders in short barrels (according to GRT and QL) if you think it matters.

It also suggests that 2970 in a 20 is already in the 65-70kpsi realm. In most bolt actions pressure signs are often not seen until 70-80kpsi often higher
