Hey Steve, do you know what load Nosler used to shoot those groups?
My friend, I have absolutely no idea.
Interestingly, it takes a lot of skill to shoot the rail guns well. You'd think that it would be a matter of BANG, BANG, BANG, but it is not. The barreled action recoils back along the two rails (or is it four rails?) and a consistent hand pressure must be applied as the unit recoils back.
I was told before that particular series of five-shot groups was fired that the 200-grain Partion in the 300WinMag was without a doubt the most consistently accurate combination that they shoot. Each lot of bullets is shot, so it was a test of a particular run of bullets.
When the results came back as they did, I was absolutely blown away. I'm not particularly a fan of heavy bullets, of Partitions, or of the .300WinMag ... but, there is was.
Yep, I still kept on shooting my boring .280 Ackley with 120Ballistics and .25-'06 with 100Ballistics. Some old farts never learn
Steve
