[QUOTE="tim_w, post: 1022338, member: 11132"] Geargrinder, THANK YOU!! You are a wealth of the exact info I was needing. No, CRF is not a deal breaker; more than anything else it was just a nice addition IF it had the other features. [B]So to confirm all the current centerfeed long actions have the same [U]inlet port [/U]opening OAL (different mag box sizes but inlet port is the same) and its more than I will ever need @ around 4"? Sounds like its almost or the same size as the ejection port. [/B] Your info on the variation between the center and staggered feeds inlet ports explains all the various numbers I was getting for specs searching thru the various forums. [B]So I can pick up just about any post accutrigger centerfeed long action and have no issues? [/B] Aside from a bolt head change if needed. Thank you also for the info on the RUM case and AISC mags. I was aware of this and the need for milling the "support bar" if full size RUM cases were used. This one will have the shoulder pushed way back so I think its a moot issue for me. But below is some of the details Currently the 300 rum has its shoulder body junction at 2.38"-2.39" range. Mine will be closer to that of of the 300 Win Mag around 2.1" so almost 0.3" of setback. This puts it just a tad shorter than the lapua for shoulder and with a diameter 0.38 smaller at the base 0.550 vs 0.589.

Was actually thinking of having Kirby put one together for me on one his actions. With the ability to quickly change barrels and adjust headspacing swap out bolt heads, the savage, IMHO, makes just about the perfect test platform action Anyways that's the plan. I will also take a look at the Accurate-Mag DBM as if I find a donor one with a accustock that would save me some coin. [/QUOTE]
