[QUOTE="backwoods83, post: 518533, member: 29890"] With the reamer blueprints I looked at a 7/300wsm is virtually a 7mm wsm they are the same length all you are doing is necking down a 300 wsm to 7mm. 300wsm blueprint shows 80.4grns capacity, 7mm wsm shows 80.3grns, 7/300 shows 80.1, the only advantages is good 270/300wsm brass verses winchester brand 7mm wsm brass, to work the brass less I'd get 270wsm norma brass and neck it up, your only expanding .007". But yet these with vlds will not fit in a remington sa. [/QUOTE]
