Since the e reciever is designed to use up to the 22mag so will my Mark II BTV 22lr work fine with the 22 mag? Sorry for my ignorance but will I need a a diff mag or barrel? I did search but I've not found any info on this subject. I do know off Savages web site the BTVS in 22lr and BTVS in 22mag have diff sku's but everything else is the same spec wise
