that 1-8" is a good one, it should shoot up to 77gr nicely... makes a good mid range deer gun... Black Hills turn out a 77gr OTM {open tip match} round that shoots extremely well in both my AR's, and they're 1-9" twist...if you roll your own you should be able to go up to 80gr without a problem...
a quick search and I came up with the Patriot having a 1-14" twist... that's unfortunate, as you're pretty much limited to 55gr and lighter bullets... if you do load you may be able to push a 60gr fast enough to get it to stabilize, but I've never had any luck with any of the 22-250's I've ever owned... but then again I have killed a bunch of deer with a 55gr bullet in the 22-250... you just need to pick your shots and hold'em tight... head shots and slip a good lead tipped bullet between the ribs, will take'm down quickly... stay away from the big bones, shoulder blades, spine, pelvis etc...
