Settled on 63 gr of IMR 7828. remington 9 1/2M primers (only large mag primers I could get my hands on) TSX 130 gr
Partial full length sized brass trimmed to 2.490"
Seated to COAL 3.180"
3 shot groups on cool barrel have ranged from 3/4" to 1"
I tend to think if I do my part correctly it's 3/4"
I'm very happy with the handloads especially considering this is the result of testing just one powder with one bullet and one primer.
I look forward to trying lighter bullets in the TSX as well as other bullets such as partitions or what ever I find in 6.5
I'll be trying some winchester, federal and CCI primers as well and likely another powder too.
The handloading and the trigger are what I credit the most to the accuracy improvements on a cold barrel. The floating and the bedding I credit for consistency, repeatability in varying weather conditions and as the barrel warms up.
For the most part I can say It will shoot this way spring summer fall, winter, wet, dry etc.
