I have a Vangard 270WSM with Timney trigger. It routinely shoots SUB MOA @ 1000yds for three rounds from a cold bore. If wind conditions are good, it is usually a 7 inch group with only a 2-4 inch vertical dispersion. This is a hunting rifle and three consistent shots is all I am after. If I can't get it done in three, I need to kick myself in the *** for taking the shot in the first place, and get back on the practice range.
150 Berger
Norma brass
RL22
Fed 215M
3150 FPS
I am in the process of testing Retumbo and H1000 for better temp stability and using Federal 210M for even lower ES. Both are performing very well in my 270WSM and I am getting an easy 3200FPS with both powders.
The Vangards magazine is very generous and I can load the big Bergers into the lands and still fit the mag. However, both my 270WSM and 300WSM have performed best with some jump to the lands using the Bergers. My 7Mag likes the 180 Berger into the lands. Other bullets shot great in my rifle and produced great groups right out of the chute with no fuss.
The big Bergers are the last bullet I would choose to shoot small groups at the 100yd line using an off the shelf sporter weight hunting rifle. My 100yd groups with the big Bergers are most times unimpressive. But with some tuning and testing, the Bergers can really connect at long range.
