[QUOTE="ELR Researcher, post: 895885, member: 19541"] The spec (for my gunsmith) reads, "NOTE: Throat both barrels for zero jump/jam at COAL = 3.650 with Berger #33106 (Hybrid OTM Tactical 300 gr)." That is what I expect to end up with. [The COAL is to fit my AI 338 LM CIP mags. I provided him one mag and cartridge brass and the Bergers. He is also building me custom dies to match.] My barrels will be nitrided and I will test from there. I want the barrels nitrided before doing any testing. One of the barrels is a "salvage" rechamber job and will be used only for fire forming. Depending on how the testing goes I will purchase additional barrels - possibly changing the throating at that time. I am trying to keep the initial overall rifle weight down to just under 17# to allow 1000 yard NBRSA competition - the "good" barrel is only 26" and fluted. Going forward I will swap barrels to shoot ELR - longer barrels, possibly gain twist, etc. I may well attempt to engage Defensive Edge to go Shawn's +P. [I say "attempt" because I don't know if he'll be willing to spend the time to +P a 338 NM.] Probably too much info. Its been typed so... [/QUOTE]
