EDIT3: Primarily looking to see if anyone has first hand experience with 7 SAUM feeding reliably in a Sako 85 with factory double stack long action mag / action at this point. Everything else is pretty much figured out.
See post #8 for feeding experience with 7RM as well.
EDIT4: Missed the obvious answer... oops. Thread resolved. Will post results later if people want to know.
------------
Not building immediately, but trying to decide between a 7PRC and 7SAUM for a Sako 85 hunting rifle and would like feedback on 3 things:
Key question - 1. Will 7 SAUM run in a Sako 85 long action (with Sako long action mags, originally 7RM). Anyone with experience know if 7 SAUM runs / feeds reliably in these?
2. How much of a difference is there in velocity between the two (assume 24"/24.5" barrel for both)? Can't find a lot of mfg published 7 PRC data, but looking online it seems a 180gr bullet (180 just as an arbitrary example) will go about 2800-2900 in SAUM and 2900-3000 in PRC?
3. Is one significantly easier to reload for or run on vs the other (ex: accepts more powders, wider nodes, etc.) or easier to keep running in a rifle (ex: doesn't need to be cleaned every 50 rounds to prevent carbon ring, oddities with brass, etc.)
Edit: Forgot to mention, lack of factory ammo availability for both is not a concern (reloading). Already have 7SAUM brass / components / dies (i.e. intermittent 7 SAUM component availability will not be a problem). Do not have 7 PRC anything yet, so if it's all "close enough" and 7 SAUM will feed reliably in a Sako 85 LA, then I'm probably going to go SAUM just to save myself money on additional equipment.
Edit2:
Plan on using copper / solids in the 150 - 170 weight range.
