I have been looking at an Accuracy International AICS Stage 2.0 Long Action stock for my remington 700 chambered in 7mm. I don't see one specifically for that cartridge. The 338 and the 7mm cartridge are close in in size. So my question is will my 7mm action fit the 2.0 long action stock specified for 338? If so, will their be any issues using the 338 magazine with a 7mm cartridge? Thanks.
