A tale of two 338's - 10/05/18
I bought a M-70 classic stainless boss equipped 338 WM in the classifieds here last week, got it yesterday evening, brought it home and to the rifle cradle it went, coated the bore with carb out, while in the rifle rest, I mounted, loctited, and lapped a set of tallet lw's in, mounted an old spare matte 4.5-14x40 AO, [ I know, chitty eye box, but hey, it was there] after the carb out treatment I foamed it up good with wipeout, let set for three hrs, coated it again last night before bed, and let sit upside down all night.
Got up this morning pushed a patch through it, and mounted a painted, bedded and pillar bedded factory Tupperware stock I had Darren75 here at the fire paint plus add a spacer to give me a lop of 13-7/8ths inches, went to see my old buddy at his machine shop, he cut the threads for the boss, filed the muzzle flat, that will do for now till I have time to take it to my 'smith for an 11 degree recess, came home and went to the load shop, 70 grs of RL-17 sent the 250 gr A-Frames to 2743 fps in the Winchester, went in and grabbed my 26" barreled Kimber SA, it registered 2796 fps, not such a bad loss with the Winchester having only 22"s of barrel left.
I fired a couple with the Winchester to get close to center at 100, moved the target out to 200 yards, while it was cooling I fired 5 rounds from the Kimber, they went about 1.5" for 5 at 200 yards, not surprised, that old rifle has been accurate with any bullet I've ever fired in it, I miscounted my ammo, had only four rounds left loaded with the new brass, the Winchester, chitty crown and all put 4 rounds into roughly the same 1.5"s at 200 yards, shocked the hell out of me, boss hell, who needs em.
Both rifles weigh right at 8.5lbs all up, I am a happy bastard today.
