This is a Mosin Nagant I converted to 300WinMag with a Krieger barrel.
I was using a 125 gr Nos Bal Tip

1.2" 5 shot group at 100 yards.
I built 3 or 4 rifles a year in September and shoot 3 or 4 animals in October.
With scope, sling, bipod, cheek rest, ammo, and rear bag...... I am lucky to keep them under 10 pounds.
Here is a Rem700 250 Sav I built in 2020 with a Lilja barrel and Gold coin in the bolt handle..... at 8.25...
I have built BAR pressure regulators from scratch and I have modified regulators.
Much easier to modify a $12 part.
With an FAL one can tune the gas bypass with a turn of a knob. This adjusts the rifle to the ammo. Enough gas to operate without jamming[small enough bypass hole], not so much...
I built 4 rifles in September:
Deviant Defiance 7mmSTW
Mosin 25 Krag Ackley
Rem700 250 Sav
I drove 900 miles
I sighted the rifles in with bipods shooting prone at 50 yards, 100 yards, and 200 yards.
I sighted them in until they hit the 1/2" red dot at 200 yards on a...
I cut major diameter at 1.062", and the crests were not even pointy. Fits better than any rebarrelling I have done. No side to side play with just a few threads engaged. Rotates very smoothly. I am impressed with this action!
I have pushed a Sav 219 in 30-30 to 92,000 psi in an overload work up 10 years ago.
I have also done a stress analysis on a similar break action and find them to be stronger than the basic bolt action; 98 Mauser, Win 70, Rem700, Sav 110, etc.
I thought I got QL when it hit the streets in 2000, 20 years ago.
I think I got a free trial.
Ladder tests are useless to me. I found no repeatability in 2002 when I experimented. I have new rifles each year and only a couple days to sight them in. I have only shot a couple animals beyond 600...
I build 3 or 4 guns a year for my hunting. I have only shot a couple animals at 630 yards.
Usually I stalk to 500 yards.
I have sighted in a number of rifles to 600 yards and never plan to go over 8 moa away from a 200 yard zero. Short actions can't do that, so I limit them to 500 yards.
