After years of wanting one and finally got a chance to shoot one last year I finally pulled the trigger the other day. No ammo to to be found so I bought a Hornady custom die set. I have primers, powder, and j words on the way. Just down to finding some 10 mm brass. Well, maybe I didn’t do my homework after years of procrastinating but from the video I watched this morning from fortunecookie45LC I am not wondering if I have to buy a barrel right off the bat? Basically from the informative video he is showing that the chambering in glocks are so loose that brass gets “bulged and wrecked” on the very first firing and buying an aftermarket wolf barrel with a tighter chambering is needed for reloads and cast boolits. Sounds like this pertained to 40mm calibers mostly. I bought a hornady custom die set. Would think FL resizing the brass would put my brass back to specs? So can some you experienced glock 10mm owners please enlighten me on the matter?
