I saved up to buy a once in a life-time rifle. Got the SBGM in .300 win. mag and have had nothing but problems. The stock cracked by the mag well and the rifle shot 3 inch groups with every load but Hornady. It shoots 1.5 with hornady, but the heavy mags do kick pretty hard on a sub 7 lbs rifle. 1.5 may sound ok, but for $1,300, I would expect 1/2 inch groups. Really pisses me off. Thinking about selling it and getting a sako. My $300 and $600 rifles do it. I can take my remington 700 and put all ten rounds in under 1 inch.
It does carry great in the mountains and I have killed 3 elk with it so it's not totally useless, but it brings me to tears and great wailing when I zero and it has flyers all over the place. I might try an accumark in the future when I start making some money.
