[QUOTE="remingtonman_25_06, post: 298920, member: 1403"] I'm about to start working up a load for a friends new 257 WM for antelope season which is only a short month away. Its a custon built stainless bdl rem 700, w/26 lilja, w/ rem mcmillan stock, built by Shawn Carlock of Defensive Edge. Very nice rifle. He gave me 100g NBT's and H4350 to start the work up. But, first I have to finish breaking in the barrel and mount his 3-9 leupold in leupold bases/rings. He only shot 5 rounds w/115g Berger VLD's to start the break in process but he works out of town and does not have a lot of time. He knows I love to work up loads for rifles and usually pretty good at it, so hes letting me have at it. He only has 20 brass for it and the 15 are still loaded with the 115g VLD's. I plan to shoot 3-5 shot groups and then scrub it down and it should be pretty much broke in then. He bought a Redding neck size die set so I'll neck size them and start figureing on a load w/100g NBT's and H4350. Anybody have any luck with this combo?? According to quickload, 64.4g is MAX for a velocity of 3563fps w/H4350. I was thinking of starting at 61, and go to 62, 63, and 64, 3 shots each, so that would be only 12 shots. Depending on how those shoot, I'll go in .5g increment to find the sweet spot if need be. So should find a load that will shoot 3/4" or better at 100 yards within the next 20 rounds. I'm not sure how it was throated so hopefully it dont have that long freebore to not reach the lands, I"ll find out later tonight by denting a fired case neck and chambering it with a 100g NBT. keep you all posted on load development.
