[QUOTE="Broncoguy, post: 1726799, member: 58280"] Input need. Doing a 338 max in November, and intent is for a mid range (1k) compact setup. I’ll be in a folding chassis and thinking a 22” barrel so if I choose to shoot suppressed it won’t be unwieldy long - Tbac 338. I got a couple 7 max cases and necked up to 338 and set a 250 Berger with full neck bearing on bullet - OAL 3.1600. So here’s the Q’s - with the 250, how much more forward could I hold out bullet and still have good neck bearing/tension. - how much free-bore does the 250 like? Or what’s the optimum chamber length to lans for max powder/speed. - zero experience with the custom bullets out there, but will there be beneficial gains to goin that route - 240 Bulldozer for instance. - any ideas on this round for velocity loss per inch? Cheers [/QUOTE]
