You didn't say at what distance you are shooting, rams at 200 or 500 M ?
First, I would try some .310 sized bullets, and if you are shooting at rifle ranges [rams @ 500 M] then I would look at 311284.
As Charles B saidIf you are not going to cast why go this route? While I like Montana Bullets they are a bit high on price compared to Amax bullets, which shot well in my rifle.

Unless you are shooting at pistol Sli. ranges and the match Dir. requires loads that don't damage the targets , then look at reduced loads and look for supply houses that sell seconds /blems, Midway had some 30 cal seconds as well as did Powder Valley
