[QUOTE="Max Heat, post: 840689, member: 43153"] That's quite a few replies to respond to, so I'll try to generalize. In my quest for the ultimate get-there-in-no-time-"flat" MR-to-LR round, I have exceeded the charge levels necessary for good accuracy, in the stock 26" barrel. MY reasoning for getting the all-out 32 incher, was so that I could use lower charge weights that will get me my accuracy, WITHOUT having to pay the "penalty" of lowered velocities. I believe the lack of fluting will also help improve accuracy, by making it more stiff. And the way I see it, more weight = more stable = more accurate. Imagine standing in a field, trying to keep the crosshairs of a 36x scope centered on something hundreds of yards away (and possibly moving), without having anything to lean yourself or the rifle on. VERY tricky, to say the least! I was was only using 600yd as an example, as I'll be shooting between say 200 and 1200yd. It's very hilly territory where I live, so unless an oportunity for a hilltop-to-hilltop shot arises, most of my "game" shots will occur at the lower end of the distance scale. Since the RUM has a fixed-power LR scope on it (36X), I most surely WILL be using my standard RM (S110), if I decide hunt IN the woods, since the scope on that one IS adjustable - down to 6X. FYI - As far as weight goes; drop, drift, and TTT of the heavyweights ONLY wins out at 900+ yards (at max 7RUM loadings). It is the fpe alone of the heavyweights that undisputably reigns superior at virtually ALL distances, but increasing WITH distance. I"ve already gone 1 step up from the 120's that I used to shoot in the RM. With 2 steps to 180 (I HAVE shot some of them in the RM - my shoulder could DEFINITELY feel the difference though!), and 3 to 195, I will get there in good time. [/QUOTE]
