i handload all of my guns. my 7-08 with jacketed bullets is on the third case trimming, each case gets around 4 or 5 shots. my other guns that shoot cast boolits haven't seen a case trimmer yet. i really like this!!! i am a newbie when it comes to cast boolits. no one told me about trimming cases!!! i've shot them going around 9 or 10 times and i have yet to trim them. this is great!!!

my 45-70 has a max. case length of 2.105" and the trim to length of 2.095". my cases, ready to reload, are an avg. 2.096". the cases already shot, but need a full length sizing die, are 2.090". my boolit is 405gr fbfn and a charge of h4198(35.0gr).

my 444 marlin has a max. case length of 2.225" and the trim to length of 2.215". my cases, ready to reload, are an avg 2.216". the cases already shot, but need a full length sizing die, are 2.217". my boolit is 275gr ranch dog and goes with either h4198(41.5gr) or rel7(39.0-42.0gr).

my 30-40 krag has a max. case length of 2.314" and the trim to length of 2.304". my cases, ready to reload, are an avg 2.306". all of my cases are ready to reload, sorry:). my boolit is a 165gr ranch dog and a charge of h4198(25.5gr).

i might have to have all of my guns shooting cast boolits! well, two of them are long range deer shooters(270win and 6.5 creedmoor).

i must be doin' sumthin' right. what about your cases? do they need trimmed or don't they?

Well, it pretty much depends on the case's taper or lack of.

My 22 Hornet gets regular trimming while my revolver cases and 45/70 cases only see a carbide cutter early in their lives for a uniform crimp. The military 30 and 31 calibre cases reserved just for cast boolits get trimmed once and then they, like your cases, spend most of their lives sans trimming.

I still "square" them off every now and then.

if you measure your chamber in that area you might find you actually need longer cases not shorter ones.
