[QUOTE="AD5GB, post: 1242357, member: 98380"] Greetings, I'm having a challenge. I've got a Win model 70 push feed that I had rebarreled - 27" Brux stainless in a heavy sporter taper. It's epoxy bedded in a Boyds laminate stock and fully floated - at least an index card thickness anyway. I've put in a 375 H&H magazine box and bolt stop and a 7MM STW follower to increase the magazine length as well but working up loads for this thing is becoming problematic. I'm afraid I'll burn the barrel out before I find a shooter. My 270 spoiled me I guess - found it within 60 rounds. Anyway, it'll shoot "OK" groups with a little care - meaning about 3/4" @ 100 using 165 or 180gr SSTs (3202 and 2978 fps respectively) seated .020" off the lands. I've been trying to find groups with 190 SMKs and 200 and 212 ELD-Xs and it's maddening. 3/4" -1" ( or greater ) seems to be about all it'll do. The maddening thing is during the course of inching up the powder charges I find loads where 2 want to share the same hole and one is a "flyer". By flyer I mean it's 1/2" - 1" from the pair. Also I find loads that actually decrease in MV where the powder charge increased only to find that the next incremental increase sort of made up for the 2 if that makes sense. (this could possibly be chrony issues) For example: Today I went out with 190 SMKs seated .040" back ahead of IMR-7977 in 1/2 grain increments from 71 - 75 grains. Group averages were: 2747, 2765, 2790, 2775, 2815, 2777, 2793, 2871, 2948 None of these were stellar groups but the 72 and 73.5 gr charges had 2 sharing the hole and one 1/2-3/4" off. I've used IMR4831, IMR7828, H-1000, and just tried Retumbo with the 212s (promising) with various seating depths but that I can't find anything to tell me where to start focusing is maddening. Cases are sorted, weighed etc with basic prep (not neck turned) and neck sized; Either Rem, Win, Hornady or PPU. CCI-250, Fed-215, Rem-9 1/2M. Maybe 3/4 MOA is the best it'll do? Thoughts? [/QUOTE]
