[QUOTE="highdrum, post: 1822880, member: 13732"] I just ordered a brux 1:8 270 barrel #5 contour. Have an old rem 700 that has a 32" truck axle 300 rum tube one it. I'll add a wyatt's mbe3 box and build a 27 nosler on it. My worries: saami spec chamber has no freebore and has a neck Dia of 0.316, I usually like 5 thou for expansion so loaded case should measure 311, bullet is 277 so brass would need 0.017 thick necks. I don't believe they'll be that thick and the chamber will have a sloppy neck. I will order some Bertram brass, as their nosler case line of brass has actually been pretty consistent and strong case heads. I bet that'll be around 0.0145" thick as their 28/30/33 nosler brass is right in that area. I have to custom order a reamer with a 311 neck and probably freebore of 0.120 and 1.5° lead, unlike the 1° of saami, that gets burned out too fast. [/QUOTE]
