For those who have rsaum, wsm or similar cartridges what mags do you use? Is it better to use a 20 round with limiter or just load less and not use the limiter? With the 6.5prc it loses 20% capacity on 308 mags. Not a big deal on that! I tried loading a 25 round pmag as much as possible, but after 12 rounds it would not position correctly. Probably not a correct curve or a best follower for yhe cartridge? Insite and/or imput would/could be appreciated!
