[QUOTE="Jud96, post: 1262364, member: 69478"] From my experience the books seems a little slow most of the time. For instance, my .243 load with an 87gr V-MAX. According to the book I should get 3200-3250 fps with IMR 4350, I am making a chrono and drop data confirmed 3370fps. I have a 26" barrel and the books have 24" but 2" can't be giving me an additional 120-170 fps I wouldn't think. My go to load now uses IMR 4451 and gets the 87 going 3430fps with only .5gr more powder than 4350. My only pressure signs are slightly flattened primers, this is where I call it max. The odd thing is though, with 70gr bullets in the same rifle, I am running 3600fps a grain under max according to the books but the same speed as them or slightly faster. Odd that one load at max is way faster and the next one is the same as the book. My Dad has the identical rifle to mine and we literally shoot the same loads with the 70s and 87s and even use the same dope card! Pretty wild that worked out like that. [/QUOTE]
