After reading the thread on BOSS shells losing velocity in cold temps I am wondering. What shotgun powders offer temperature stable performance? I would like to try my hand at some low recoil 1 ounce steel or bismuth loads. Hunting temps very from 70's in Aug to below zero in Jan.
https://www.ballisticproducts.com/b.../curmudgeon_articles/060329_hotcoldpowder.htm. if you are shooting 1 ounce loads, I’d look into the Faster burning powders for colder weather. universal make a nice one ounce steel load.
depends on the payload but with a little research with the powder companies websites , it would give you a better understanding of what you need ! There are several powders that are good for what you want to load , just , some are better than others !
I had understood they tweaked the formula for blue dot to make it less temp sensitive. Even so, I'd think a hot primer in a high pressure load would go a long way to mitigating any temp issues. But I don't use a lot of blue dot, so I don't know that to be the case.
Check out Ballistic Products Inc. They have many steel 1 oz and 1 1/8 oz loads in their Advantages book you have to pay for. For steel shot reloading Alliant's STEEL powder is THE BEST!!!! and you get free load info from them. Many 1 oz loads are zipping over 1600 fps of which you don't really need unless you are reloading the smaller shot sizes.
Usually I will not argue but this time I will. By very cold I meant sub zero Fahrenheit. Blue dot starts to burn differently and it sounds different. Gun still goes boom but I had concerns so I asked around and the old timers said that blue dot isn't the best all around powder and it shows when it gets where the snow screams when you walk on it. Its the only powder I've ever used and I've shot it a lot. It dont like cold.
