[QUOTE="J E Custom, post: 137489, member: 2736"] Mudstud Ok but don,t use this data with out starting low and working up. The rifle is a browing B-78 high wall with a 31.325" #6 tapered mcmillan hand laped fluted stainless barrel with a 4.5x14 tactical mill dot leupold. Loads were 82grs IMR 7828 140gr NOZ ballistic tip @ 3783fps. 93grs H 5010 140gr NOZ Partition @ 3769fps. 82.5grs Reloader 22 140gr Noz Partition @ 3804fps. 83grs IMR 7828 130 Sierra match king @ 3860fps. I tried 120gr bullets but lost accuracy (I may have over rotated them @ 3970 fps. All of these loads required a 3 foot drop tube to load the powder with out breaking powder grains. And rem 91/2 mag primers. to hold SD to under 10 Fed 215 primers avg,20 to 25 and were hard to extract. I am experimenting witk a 7 RUM because of the new powders and more case capacity. Still looking for the flatest long range combo. I,m also looking at forward ignition to reduce throat erosion in over bore cartridges.(the price you pay for speed).
