OKAY i remember now thats what it was a drop in for! I think it had real good velocity and muzzle energy.THat would be a good thing to have for my XD 45 Tactical.
Oh EFK Firedragon DOES make a drop in 400 Corbon barrel! OMG!
i wonder if you could beat the 357 sig speeds by necking it down again to .355"
im not sure since the 357 sig is a really high pressure cartridge. it would be pretty cool to have a 45 acp gun that could shoot .355 .400 and .45 caliber bullets
