for those who reload and don't know why not just certain ammo, but certain bullets designs don't work in their firearm. for the factory ammo buyers this doesn't apply to you. if you have a favorite factory ammo choice go ahead and post away, just give info on what you use it for and firearm info. i don't shoot any matches only shoot for fun and riddance of varmints. bullet weights range from 55 to 350 grains in 22cal to 458cal. fmj is what i use most of, but do have gummy tips, match and bthp also for reloading. barrel lengths from 8.5 to 32" and so far no favorite weights of bullets. bullets from many manufacturers, but no favorite brand either like most do (reference from other gun forums). nosler and barnes are the most expensive per bullet which is my reasoning to not buy any more when price per is over $1. i do have a decent collection from both before covid pricing got involved. with the different barrel lengths and cartridges that are for them dictates weights i choose (in most cases) and types.
well, on another gun website, i cruise the reloading threads.
one reloader of many years (i cannot recall how many) said he seats his 9mm at 1.135 OAL. no matter the maker of the bullets and this applies to RN....
i was setting the OAL to what the Lyman book said, and in fact, the other books i have, were very much alike.
so the seating/OAL was much shorter that the 1.135 the guy said he does.
as a result the 2 CZ 75 B's that i have, will not load up at the book OAL
once i started setting the OAL at the 1.135 depth..??
perfect loading, chambering, and shooting in those CZ's.
i'll stick with the 1.135 OAL on my 9mm reloads...although in future reloading of the 9 mm, i can try increasing the OAL a tad more, maybe closer to the factory OAL?
now, a lead cast bullet measures at .566 and a Berrys copper coated measures at .554.....
but, i get the lead cast being shorter OAL, due to the wax ring. Berry's there is no wax ring.
this explains too why when i used to buy my reloaded ammo, they would not shoot out of my CZ's, the OAL was much shorter.
i checked my Federal 9mm FMJ, and Blazer and OAL is at or about, 1.152......
the Lyman book calls for an OAL for lead cast at 1.045
even for a 147 TMJ Lyman calls for an OAL of....1.115.......way too short for my CZ's to load, chamber and shoot.
