Len, i have been a stranger to this forum but i lost my password and just had a new one sent to me,anyway. I'm building this gun on a remington 700 cdl having a douglas xx 27 inch barrel (after finished) screwed on then reemed do you have any input... 338edge or 338-300 what ever you want to call it. does this gun need a muzzle brake to shot without kicking the living daylights out of you? i need dies also do you use 300 ultra full length with a 338 or .364 neck sizer. what do you think about the douglas barrel? any good? Whapaho from washington thanks oh yah,i almost forgot is the barrel long enough or should i have went to a 30 inch i'm looking to get 2900+ at the muzzle with the 300 grain smk. Im needing brass,dies and a muzzle brake. what do you think of OPS, inc brakes?
