|Uncle Paul||Clawman saw a show once where the armorers were building bolt guns from parts they started with the Remington receivers and machined almost every part of the gun to their specs and after it was done they developed a load that was for that specific gun only, I remember them showing the loaded boxes of ammo that had the guns serial # on it.With the newer guns and the semi autos Iím sure it just a ammo loaded just for the military to meet there specs.YATYAS I Googled your Question and lots of info on what youíre looking for but look up a formula developed by W.W.Greener it will get you in the ballpark I think|

I am intrigued with what the military uses for snipers. We all think you have to work up your load for a specific rifle. The snipers are not sitting in a tent in the desert reloading custom loads. If the military can create a load for all of their sniper rifles why aren't there recipes for civilians to use in our rifles?

|YATYAS||I have established that the two are in fact different. The burn rates are very close but they are different. IMR lineup has its own temperature resistant powders that I may have try because the H4350 is impossible to find.|

I was walking with the owner of Bullbery Barrels out of Hurricane UT and he told me a story about an experience he had while testing loads. He had a good load worked up for a particular cartridge and laid a box of shells in the windshield. When he shot the first round the barrel blew up due to too much pressure. The shells were extra warm from laying in the windshield and created a pressure spike.
I have called Chris Hodgdon at Hodgdons powder and he has been very helpful with loading characteristics of their powders, if you want to debunk the myth that the two powders are the same.

I think elevation changes have more affect than temperature and besides todays rifles are a lot more accurate than most shooters abilities. Another powder I've had good luck with is RL-19 & RL-22, you'll have to experiment and see which one your rifle likes best, that's what I base it on.|

This could also be a safety issue if a bullet is loaded to the max and sits in the sun for a while then shot in 100 degree heat. Could generate a pressure spike. There are a lot of things to consider which is why I find this interesting and I am looking forward to diving into it. If I didn't worry about getting the most out of a hand load then I would just by factory ammo.

|Uncle Paul||Yatyas you never said what your goal is reloading or what cartridge you will reload but unless you measure your groups with a quarter inch ruler or your closest target is 1000 yards or more you might be wasting time worrying about temp effect on a powder. When I started to reload metallic shells and would hear things like temp effect on shells I would try to track down the source of the info and most of the time I never could even with the internet. I trust the manufactures of the powders and they have a lot to lose by selling a powder with issues. Like it was said go to their website and look it up and if you have a question you can always ask them a specific question. One more thing never listen to anybody that says this and this powder are the same just a different label this thinking gets people hurt. Unless I see load data printed by bullet or powder maker I donít load it.|
