Thread: Ream to... 7SAUM or 284

284 would be easier to do, cos the jump to SAUM means also having to open up bolt face for the magnum case.
Not sure if u can do this on XBolt ? The other issue is mag length - from memory the XBolt is not overly generous? That's going to limit you especially with the 284. You need full 3 inch or a tad more for 284. In terms of fps there's not a lot in it, 50-100 fps in favour of SAUM from my experience. Both a decent step up over 7-08.
