How heavy is it?I may need an oil change after shooting this thing tomorrow.
I really do not know what to expect.
I fireformed with just 80 grains of H1000, then fired them a second time before starting load work up.
I treated it just like a 6BRA.
The cases are fully formed and sharp after the second firing.
One thing that I noticed was even at 2950 fps, which I assume from research is a good velocity for this chambering, the primers were still round on the corners with no other signs of any “high” pressure. The bolt opened with no resistance what so ever.
From what I have read, pushing the 300 Berger over 3000 fps leads to problems. So I avoided it, working with seating depth and velocities between 2900 and 2975 fps. Nothing seemed to tighten it up.
And as I said, at an average 2950, the velocity spreads were 10fps or less.
This all points to either I am way out of the tune window, or something mechanically is wrong that I cannot pin point at the moment.
If you can find some N570I am shooting with my standard Benchrest equipment. This is a Benchrest Rifle, abiat a very loud one
I guess you will just have to take my word that I know what I am doing as far as the handling of the rifle.
What I am not good at doing is tuning cartridges with 100 grains of powder and bullets that weigh more than the entire loaded round I usually shoot.
That’s why I ask questions.
What he said. Mine woke up with 570. Also had to increase neck tension. I did so by using smaller bushings. I am using sorted Berger 300's as wellIf you can find some N570
I concurMy guess is that it just does not like this powder. Seen this in several different calibers, as I am sure you have. Find the right one and all is good. It is still early. Good luck.

The Savage long range target rifles are levels above the budget lower tier guns that most people think of when they hear “ Savage “ . I have one, a Model 12 LRPV in .223 . An absolute tank of a gun, typical Savage accuracy, and functionally flawless through 2,000+ rounds.Just to scratch the itch I would get a factory savage long range 338LM and see if you're going to enjoy it before to much investment. Great factory ammo offerings and minimal up front cost to determine if you'd stick with it. Then if you like it built a purpose built ELR gun.
ThanksJackie, Whiddens has N570 again:
