Took the rifle to the range yesterday with a ladder test of loads for the 129gr Hornday SSt (great bc). I set up with H4831SC, CCI primers, and Rem brass. I found a node at 45.0 that gave me .48 in 5 shot group at 100. Not too bad for a skinny barrel.
The 260 Remington Mountain Rifle will stablilize the 129 SST and will produce a 5 shot sub 1/2 minute group at a hundred. I did it yesterday. It will be my light carry gun this fall.
You just gotta love it....
