Xr-100 in 308
I bought 3 of the XR-100's in .308 from gander Mountain in Houston, 2 at one place and one at another.
I got them for $600 each, because Gander mountain was having trouble selling them. They wanted $900 for the XR-100 22-250 beside it.
I sighted in, and put scopes on all 3.
2 of them, I put Nikon Monarch 6.5-20's and one of them I put a VX3 6.5-20.
I tried several loads with several bullets. I found an accuracy node with 44 grains of Varget behind a 168 SMK, cci primed, Lapua brass.
All three rifles shoot identical groups of a single hole, that measures about 1/2" to 5/8" outside so, subracting bullet diameter, about .200" group.
The rifle also likes 168 Hornady A-max bullets.
My friend Nathan has a 22-250 XR-100 and it shoots very well also.
The short, single shot platform has no special bedding, yet still performs.
