May i recommend the hornady lock n load bullet compararater you need to buy a 338 bushing, a 338 lapua modified case, the attachment that goes on your caliper, and i would advise you to get the rod that measures how far off of the lands you are. hope this helps (i also have the savage fcp in 338 lapua)
Just orderd the Comparator w/338 bushing from Midway, I already have the Lock n Load OAL Gauge, and moded case, Thanks for the input though.
It is not uncommon, I would almost say the norm, for the factory supplied brass w/Hornady, their gauge to be off a fair amount. I have 1/2 doz. and the closest is .005 short of my fired case, the worst is .019 short, on my 340 wby. I use the Sinclair tool, for which you use your own fired brass. When you get your comparator, measure your '' case gauge'' and compare it to your ''FIRED'' actual chamber size, you want this number for shoulder bump. Then you will know if you have any difference, for which you would want to account for.
Got My Comparator today, measured My chamber to be 2.990" to the lands. I'm going to load up a half dozen or so rounds from .020", .025", and .030" off the lands and see whaere that gets Me. Has anyone ever had much luck using IMR4831 with this round? Just curious, I have a lb that My buddy picked up for Me and wondered if it would be worthwhile to even try this powder with a 300gr pill. I've got some H1000 and RL25 on the way, might have enough US869 left for 8-10 rounds as well.
