[QUOTE="Orange Dust, post: 2394492, member: 92702"] How much do you shoot THAT gun when it is hot? Temp stability is way overplayed on the internet. I don't care how stable a powder is, you have choices. Work up a summer load and a winter load for the rifle. Don't shoot it above 90deg. work up the load when it is above 90deg. Don't load to MAX. etc. Temp stability is a relatively new thing. Unless you are running fairly hot loads you will most likely not notice with a hunting rifle. As for the barrel length, you are correct. Shorten the barrel and you get more blast, fireball, and concussion. However, if you put a chrono on it, The powder with the highest velocity in a longer barrel will usually also be fastest is a shorter one, although is will certainly be slower. In general, the powders in the faster range for the cartridge will work better with lighter bullets and slower powders are better with heavier ones. When choosing a powder I usually start with whichever one shows the highest velocity with above a 95% fill rate, or (lately) whatever I have onhand closest to that in burn / fill rate. Choosing the powder is not as critical as choosing the bullet. Hope this helps. [/QUOTE]
