45 colt blowback. H10 big boy octagonal barrel
Shooting to different makes of ammo with different loads. The HSM 200gr loads have a bunch of blowback.
The Magtech 250gr is quite a bit less. I've read blowback is not uncommon for 45 colt.
Seems like a lot especially in the lighter, faster load. Pictures included. Opinions?
