I will be buying a Remington 700 long range 7mm rem mag with the bell and Carlson m40 stock in the next couple weeks. when I get my taxes back. I have a Remington 700 sps 308 and I hate not having mags. the one from midway I am looking at is Wyatt's Outdoors Trigger Guard and Detachable Magazine Assembly Remington 700 Long Action Belted Magnum 10-Round Aluminum Matte (midwayusa product #483368) I want to know if anyone has used this with a 7mm rem mag or has any others that have worked well with the 7mm rem mag. not looking to spend more then $300. thanks for any input.
