[QUOTE="SQ Stalker, post: 302284, member: 18663"] Thanks for the great replies. [B]Jamie6.5[/B]> The load is on the hot side. I'm eager to see the terminal ballistics of this load. In 8 years of shooting hogs in the boiler room w/ Hornady LT MAG 130gr @ 3200FPS . . I've NEVER dropped a hog. Even a .50 Cal Muzzle Loader at 7 yards (a double lung shot that blew lung and rib chunks on the ground) the hog still ran 60 yards. I'm not sure on the brass life but no failures yet. Some of the brass has 4 loads on it so far. As far as why to get a custom barrel I hope to improve in a couple areas. 1. More consistant groups, w/ less fliers. Today I had 3 shots in .321, 4th=.950, 5th=1.769. Max wind today was 6 MPH, a 10 MPH should only drift .6 in. @ 100yd. So its not the wind. Also barrel temp is kept consistant w/ a laser thermometer. Cleaned bore every 10 rounds or less. I just ordered a sinclair concentricity gauge and a Holland ball mic to try to cut down on fliers. 2. Also I'd like to get a thicker barrel with flutes to keep the barrel from getting hot so quick. 3. With the extra velocity gained from 2" (maybe 100fps?) I can back the powder off some to let the brass/rifle live a little longer and also help w/ the barrel getting so hot. 4. Another small benefit will be that with the extra weight (1LB, may go thicker to gain 2LB) the felt recoil will be less. 5. And I just love to tinker and enjoy precision equipment of any kind:D I've thought of going to a .270 AI but I'd rather not fool with having to fire-form brass. Also I've found better consistantcy with FL sizing (RCBS Gold Die) where the die sets the shoulder back .0015" (from chamber) and neck sizes .250" down the neck. Now I prep all my brass this way. I was getting worst consistantcy on head space from fire-formed brass than the die could deliver. This means I'd have to invest in a new die. I guess I'll give Bartlein a call and see what they recommend on barrel twist for my load and contour recommendations. Stalker [/QUOTE]
