[QUOTE="justgoto, post: 503387, member: 17125"] I load develop with my Winchester 94 in 30-30 a lot so this is right up my ally. :) Exactly what I experience, when I ladder test I increase grains by .1 increments. That could be due to the powders used. I noticed an 8 inch difference in POI height at 300 yards with only a 10 degree F temperature change. In some loads that would also open the groups up considerably. I now use Varget to get around the velocity issue due to temperature changes. Varget burns a bit slower than the powders you have listed. H4895 is a bit slower than IMR 4895 but I bet it isn't by much. H4895 is an "Extreme Powder" which is temperature insensitive, give that a try. Ballistic inefficient bullets are very sensitive to wind; just a 5mph wind can account for 2 or so inches at 100 yards. I've used the Hornady FTX bullets to cut the wind better. [/QUOTE]
