Greetings. First post, but I've gleaned lots of info over the years. Great forums.
Summary:
My 300 win mag brass is averaging well below the trim-to length. Should I trim it all to near the shortest and go for it, or should I waste a bunch and try and cull out the stuff that's well below 2.610"?
Details:
1) I'm already on my second barrel for this rifle (Savage LRH 300 Win), and burned up the first doing all sorts of experiments (and shooting for fun). The rifle averages about 1 MOA out to 1000 yds, but seems to do a bit better here and there.
2) I'm tired of dinking around, and want to put a pile of ammo on the shelf. There's only two things I want to address before I load up 300 rounds. Concentricity (gauges arrive tomorrow), and brass OAL. I doubt my groups will change much, but eliminating those variables is a "better safe than sorry" sort of thing I don't mind addressing.
3) Awhile back I bought new MAI (Lapua) brass, and it all arrived too short (≤2.610") from the get go. I think the average was down around 2.600". Other than that, it was phenomenally good for the price (~$0.75 each) and has worked well. I've now got almost all of it cycled through my gun at least once, but even the 2X fired stuff is barely reaching 2.610".
4) I don't want to waste more time/barrel/money shooting just to "grow" my brass till it all can be trimmed to match. I also don't want to cull out a bunch and waste the half that's too short.
What's your opinions on trimming everything a bit short (2.606" probably), so it's all the same at least? I know I could do the experiment myself, but putting another 100+ rounds down range, to get the statistics to find out, just isn't in the cards.
