I thought I would bring this old thread back up after reading a post from Bill Alexander on Sniper’s hide forum. I copied the following post which I found interesting concerning Wolf Steel cased 6.5 Grendel ammo.
“Barnaul cartridge who produces the steel case ammunition for Wolf has recently changed the gauge rings for the projectile production to increase the projectile diameter. Previously they had manufactured it per Russian military so excessive production die wear and variations in a fleet of barrels would not create problems other than a distribution of accuracy.
The heavy jackets used in military ammunition tend to find best accuracy in a traditional rifling form that engraves aggressively. Target barrels with canted transition between land and groove do less well and fouling becomes a problem.
This said, I am intrigued by the findings seen when shooting ELR with solid machined projectiles. Gas blow by seems more of a potential problem and a rifling form that seals the projectile well is counter to that which works with jacketed projectiles.”
