I have acquired a Remington 700 Varmint in a M24 stock. Having a hell of a time getting a load to shoot right in it. The same loads I would get sub-moa out 600 in my SPS tactical won't shoot worth a darn in this one. I have tried 168SMK 168AMAX Nosler168 with no luck. Using RL15, Varget, Benchmark. Any advise? Does the 26 inch barrel like 175's? or lighter.
