[QUOTE="Grumulkin, post: 1184673, member: 29281"] 1. For accuracy in my 30/06 rifles I've had the best success with 165/168 grain bullets. The powder used does make a great deal of difference with different bullet weights. If I wanted to shoot 180 grain bullets I'd probably start by trying H414/Winchester 760 or IMR 4064. 2. Who knows if the bullet will expand at 500 to 800 yards; I'd say probably not much out of a 30/06. A 30 caliber hole through the chest will still be deadly. Solid round nonexpanding lead balls have taken many animals and for hunting the most dangerous animals solids are many times mandated. 3. Quite some time ago I abandoned the plan to have a deer load, a varmint load, etc. for each gun. I now usually work up one load per chambering and use it for everything. A 180 grain bullet would be good for anything from squirrels to bear. 4. I disagree with the current preocupation with chronographs to judge pressure. In my opinion you CAN use pressure signs to judge pressure in a strong bolt action rifle. If there are no pressure signs I don't really care if the pressure is 70,000 psi though I highly doubt there would be no signs at that pressure. A test was once done on several "identical" rifles shooting the same load which resulted in velocity differences in up to 200 fps between the rifles. That indicates how erroneous velocity can be in judging pressure. Also consider the fact that as a load is increased the velocity may decrease as the higher pressures are reached. The only way you are really going to know what the pressure is would be with a pressure transducer. 5. I agree that accuracy is more important than velocity. [/QUOTE]
