RE: Recoil reduction for 300 WSM...
I just bought a Remington Model 700 Stainless SPS in 300 WSW, with a Ziess 4.5-12X44mm scope. I was nervous prior to shooting it the first time. To my surprise, the R3 recoil pad makes it very manageable. It kicks about as hard as my 12 gauge with slugs. I can group it as well as my .30-06.
I'm looking forward to hunting the clear cuts on our hunt club this year. You can really reach out with the 150 grain bullets. Fact is, I don't need anything more than the .30-06, but the .300 WSW is a great round.
