[QUOTE="morgaj1, post: 1939141, member: 114166"] I have a Tikka 30-06 that is the most accurate rifle I own. It is not picky at all and I have loaded 150-180gr bullets with several powders with success. My favorite load is 165 AccuBond over 56gr IMR4350. I use this for everything from whitetail to hogs to rams and would use it on elk if I can ever draw a tag. Now that I have a chronograph, I have noticed temperature sensitivity with IMR 4350. Problem is, I live in AL and do our load development and practicing during the off season where temperatures are frequently in the 90's. Our hunting season temperatures vary from the 50's down to the teens. I bought some H4350 in hopes of more temperature stability. I will obviously start low and work my way up. What has been your experience in the following: 1. Accuracy when switching between IMR 4350 and H4350? 2. Corresponding loads in IMR 4350 vs H4350? Consulting my reloading manuals, it appears that there is typically 0.5gr increase for H4350 over the same velocity for IMR 4350. For example, it appears that 46gr IMR 4350 with 165gr bullet would be roughly equivalent to 46.5gr H4350 for the same velocity. 3. Thoughts on temperature sensitivity for IMR 4350 vs H4350? [/QUOTE]
