I helped my Dad reload growing up and have been reloading pistol myself for about 5 years, but I've just started dipping my toes into rifle reloading. I'm starting with .223, mainly loading hoser ammo for 3-gun. I had a chance to sneak out yesterday to test some initial loads, and I think I found a suitable one. This is Hornady 55gr FMJ, 24.5gr H335, CCI BR-4 primer, PMC brass (range pickups within spec but not trimmed), 2.230 COAL. My chrono's battery was dead, so that data will have to wait.
Anyways, I was pretty pumped to get under an inch at 100 yards with what was intended to be blaster ammo out of a chromed lined barrel (Daniel Defense M4v5).
I do have one question. I did not crimp, and neck tension seemed fine. However, in scrounging brass at the range I occasionally find rounds on the ground whose bullets were pushed inside the case. I definitely want to avoid that. I have a Lee FCD, but am hesitant to mess with the load. What do you think, should I lightly crimp or leave it be?
