I know, I’ve read about your experiments. It’s also quite dangerous for you to publish them imo.
One of these days a rifle may blow up on you.
You pretend that you can judge the real pressures without any pressure test barrel, that’s all I need to know.
Do your thing, I have nothing against it but what is the point of promoting it?
Ever thought about that there maybe a reason the components, especially the cases you use have been disassembled again?
Again, completely your freedom to do this. But your posts create copycats despite your warnings….
It's not for the novice, that's why I said it's dangerous, with brass.
But correctly sized and neck turned brass hybrid cases it works and is an option for many who care to go there...and quite a few do.
I have several thousand hybrid cases, and from them into 6 5 CM, 308 Win, 8.6 Blackout bolt gun, 358 Win.
Besides the US military who uses them in machinguns, at full 80,000 psi, for several years, but rumor has it bumped back to 70,000 psi to 75,000 psi preserve barrel life, on full auto.
There is Bruce Thorm at Bat Machine and the maker of Alpha brass running super high pressures on Ultimate Reloader "308 W to 300 WM velocities do not try this at home," on video look it up for entertainment purposes.
They were pushing over 100,000 psi in the Bat action.
I don't do that,.. but they are with this new Alpha brass and Bat actions.
The hybrid cases are rated for operating at 80,000 psi, but mine are limited to 70,000 75, 000 psi max, according to QL the gestimate software.
The majority are held at 65,000 psi in 8.6 blkout 6.5 twist...not the 3 twist ...it builds pressure for a 3 grains lower max on those roughly rifled 3 twist barrels. I do not recommend the 3 twist barrel.
There are alot of new developments and cartridges, some can be greatly improved upon without going to magnum cases...although that's the easy button for most.
I run AR 10s at 62,000 to 65,000 psi max.
A standard load is 2853 to 2865 for 150 SMK 24" AR 10 6.5 CM with Lapua brass
There are alot of options, for those who want less performance or those who want more performance. Never go where you are uncomfortable, and always work up to loads printed anywhere.
I work on a fair of wildcat cases where little or no data is available. Like the 510 whisper...how much powder are you going to put behind that 750 gr bullet for a sub or super load? I now have lots of data on it from just shooting it, and working with QL.
Same with the 8.6 Blackout 6.5 twist, making the 8.6 versitle, as well as accurate, and not dangerous to shoot at supersonic velocities showing a better way to go, than those with the poor quality 3 twist Faxon barrels.
