First trip to the range today with the new .300 setup on the Mod 70.
The bedding screws are torqued at 40 inch lbs.
Loads were: virgin Rem brass, 73gr IMR4831, WLR primer, 180 gr Sierra MK
Groups were 1" at 212 yrds. Shot prone W/ bi-pod.
New barrel, I ran a wet patch and two dry ones after each three shot string.
Some 10yr old stuff I had with well fired brass ran about 1 3/4"
Same components with IMR 4350 were almost 3"
Should I try a 168gr MK with the 4350?
Should I bother playing with the torque on the bedding screws. Stock is a McMillan A4, very nice, BTW. The heavy 26" barrel and that stock tame the .300 pretty well, still wouldn't want to do 100rnds at a sitting though
Any tips would be appreciated, I've been out of bolt guns for 10 yrs.
