Tried sometime ago to shoot 8mm steel ball bearing to steel plate and got similar resault, ball embedded itself into the plate and did not penetrate (6mm thick plate if remember correctly). Then switched to .223 barrel and shot 55 grain fmj with same mix number and it went straight trough and left c...

This is just a guess but I would say roughly 1100J of energy at muzzle. Few years ago I experimented quite a bit with high mix hybrids and figured out some formulas that can be used to estimate muzzle energy. What is the formula? Can they exceed the accuracy of hgdt? Formulas that I used are quite ...

Hi everyone! I've been reading this forum long time now and I have built few hybrids aswell. Recently I have cranked up my mixes and I started to think about that if I have chamber, lets say 30ml and I go for X20 mix with MAPP gas with 4,66% mixture. So equation is then 0,0466 X (30ml + 1,5ml) = 1,4...
