Roy, I have taken the 338 ultra mag and reduced the case taper from something like .027" on the standard to .012" and made the reamer .547" wide in the web area to give about .002" clearance as the web on the brass measures .545. This should totally eliminate the "belly-out" look that drive me crazy. It doesn't really hurt anything, it is just unsightly. Then I gave the shoulder a 40 degree angle to put the hottest part of the expanding gases into the side of the opposing neck wall instead of into the throat. Brass is expendable, barrel steel not. /ubbthreads/images/graemlins/wink.gif THen I made the neck dimension .367 which gives me .013" neck wall thickness after turning the high side off the brass and it will run a good neck/chamber clearance. Then 7mmrhb and I squared the case heads and took that new measurement into account but it made insignificant difference. I then had the reamer throated so the 250 grain Lapua Scenar could be seated to fit the Rem box magazine and cycle well. I really lucked out here because as it turned out, the 225 grain Accubonds have nearly identical ogives and shapes so if the Scenars don't work on phone books like I hope, I can switch right over to the Accubonds without any trouble. I know they work! /ubbthreads/images/graemlins/wink.gif OK, then I ordered a drop in Mcmillan Lazzeroni sporter stock in marble finish and had them inlet for a larger size barrel. THen I got on the horn to Mike Degerness (very cool guy by the way, I highly recommend talking to him)at Advanced Barrel Systems and had him order a Rock 5r 338 1-10" 27" blank. He is then going to wrap it in his custom heat transfering carbon fiber blend and attach his titanium muzzle brake which weighs in at something like 3 ounces. He will start the wrap an extra inch ahead of normal in front of the recoil lug so I will be able to set the barrel back and rechamber several times if need be. Dies are being made by a machinist friend of mine who uses a single point boring method to make the necessary "squeeze" in the body for a hunting rifle. He will also counterbore the top half so Redding bushings can be utilized to size the neck. Very crafty this guy is I tell you! Then I have a Holland pinned recoil lug ordered so it can be switch-barreled for the .284 wildcat my uncle just had Kirby do. I also have a Sako extractor kit, a Holland bolt handle, and a Jewell trigger on it's way for it. Kirby is going to assemble it all to my Rem 700 action he has already been shipped. Riding atop this beast will of course be a Leupold long range 6.5-20x50 sitting in Burris signature rings with the 10 minute inserts installed for 1500 yard plus elk hunting. If my calculations are correct, a stiff dose of 95 grains of Rl25 should propel the 250 grain Lapua bullet at 3100-3200 and about 92-95 grains of RL22 should move the 225 accubonds at 3300-3400 hopefully. This beast should be capable of 5200 ft-lbs of muzzle energy and have enough umphh to break the shoulder blade of an elk at around 1 mile plus. Have to wait and see what accuracy will be. /ubbthreads/images/graemlins/wink.gif It might not shoot good enough to kill elk at 100 yards if my luck holds out. /ubbthreads/images/graemlins/shocked.gif Anyway, it should be interesting.
