[QUOTE="backwoods83, post: 795326, member: 29890"] ANY SAAMI spec weatherby chamber has freebore, the remingtons have about a mile and a half of it. 76grns of RE25 under a 210 berger should be a mild starting point. 3000fps is obtainable with a 24" barrel and 4 reloads per case. It will run the same 3150fps from a 28" barrel that a rum will, yes pressure will be higher but ironically barrel life will be also. Have the gunsmith purchase or rent a reamer with .060-.100" freebore. Some other considerations if this will be your go to stick. HS precision stock instead of laminate. Sightron SIII 6-24x50, imo best scope in that price range period. As for a cheaper but good 20moa base, EGW is the way to go with Burris tactical rings. I have a Timney and a Rifle Basix trigger, I like both, but to me the Rifle Basix wins, it just feels better. As for a load with 210 bergers, start midways Hodgdons data for 200grn accubonds and H1000 with Fed215M primers with the oal about .010" shorter than the magazine. There data shows 84grns compressed as max with the 200 accubond at 3.560" and it still isn't showing 65k psi, since RE25 is slightly slower than H1000 76grns is just nudging it, you need to kick it in the ***! I'm not telling you to go out and try something stupid, just telling you that listed weatherby data is very conservative just incase someone has a rifle with extremely shallow freebore. [/QUOTE]
