My old but stock Remington 700, provided I do my job groups about 1-1.5moa with factory S&B loads.
Handloads I use in the same gun are as follows:
- 50gr VMAX, 20gr Alliant Re10x, S&B primer - groups about 1 moa in three shot group: The first two shots often touch, but with the light barrel, it heats fast and group opens.
- 50gr VMAX, 25gr IMR 4320, S&B primer - groups 5/8 moa; same shooting conditions.
- 50gr Hornady SP, 20gr Alliant Re10x, S&B primer - groups the same as the immediately preceeding load.
These groups were shot on the same afternoon at 100yards, so environmental conditions didn't change. I was trying numerous loads to find one that works well for this rifle. I seated the bullets shallow in the case, to reduce the length of travel before rifling was engaged: This isn't good for in the field, because of the possibility of leaving the bullet in the chamber during an unload. But an earlier handload I had with the VMAX and max load (check tables, but 26.0gr is max with IMR 4320)of IMR 4320 produced sub MOA accuracy even with bullet seated to handle the rigors of being handled in a hunting situation.
I cannot explain why, but the VMAX and IMR 4320 load, although the first two bullets making their own distinct hole, the third was also closer to the first two despite barrel heating: The same cannot be said for the Alliant 10x loads as the first two rounds were making their respective holes form into ovals, where the third shot is what widened the group. Of course, I may be mistaken in that I spot my shots with the scope sight(an old weaver fixed, so the glass has some waves) So I may have marked the order of holes incorrectly. Regardless, my rifle likes these loads and it took very little in terms of effort to find the load, one of which was by chance meeting another range member who graciously gave me some of his loads to try. Of course, the old 222rem, is not noted for being a "minute of broad side of barn" cartridge, having an accomplished history in matches.
VMAX is very common, and works well, which is good for me because it is usually available in 50gr. I think conventional twist with 222rem in 1 in 12", so the longer bullets will not likely stabilize.
Enjoy that rifle: Sako makes a fine rifle, and in 222rem, shooting will be pleasant.
