[QUOTE="Varmint, post: 186730, member: 10361"] I have build a .338 RUM on a 700 rem ation and I used a 30" Pac-Nor barrel with three groves and I have a brake on it.I get with a 180 AB 3600 FPS using 4831SC 97grs. a 225 SST 3300FPS using H-1000 98grs. a 300 SMK 2975 FPS using Retumbo 93grs. I shoot 5/8" groups at 200 yds.The barrel is where you will give the vel. with a case this big, to burn all the powder.I also use a V-block to hold the long barrel in the stock ,so not to stress the action to much.With the V-block the barrel and the action are both free floated in the stock ... much better groups.
