[QUOTE="Broz, post: 987311, member: 7503"] CTD and others, my apologies. When I set up the profile for the 230's I used an existing profile from a 300 win and changed the bullet specs and velocity. This profile was from a rifle I had helped set up with a scope that didn't track true to .25 moa. So I had a turret correction factor entered in. My previous number were WRONG, my apologies. I just corrected the file and ran the numbers again using the 338/ 300 gr @ 2850 and the 30 cal / 230 gr at 3200. At 1000 yards in a 10 mph full value wind they both need 3.5 moa at 2000 yards the 338 needs 9 moa even, and the 30 cal needs .4 moa less ay 8.6. So the 30 cal with 230's will definitely run with the 338 LM if you can get it to 3200 fps. But get the 338 to 3200 fps and as stated there is no contest. I have never gotten a 30 cal with a 230 to 3200 fps. But know several have with RL 33. It will be interesting to hear how the barrels hold up there. I know the 338 LM from a 30" will run at 2850 for over 1500 rounds and still shoot .5 moa. I would doubt the 30 cal at 3200 would get close to that. Sorry for my faux Pas...:) Jeff [/QUOTE]
