I would like to find a load with the powders I have. They are close to other powders with the same burn rate. I know I can't use the exact data from one to another and will have to do my normal work ups. I have a really short barrel at 22 inches. 24 with the brake. Should I lean more towards a slower burning powder or go the other way for a little fast burning one since my barrel is so short. I used h-1000 before and was accurate, but I was only getting 3100 fps with a 168gr bullet out of a 30-8mm. I have a small amount of h-1000, but I have more Retumbo, H-4350, H-4831, H-414 and would like to find a strong load with those. Retunbo a slower burn then H-1000 and the rest are a little faster.My barrel length is not helping with FPS and that may be my high. I would like to get 3200 fps with a very accurate load. I have found some data with Rl22 and 25 and one with IMR 4350. The only one with 3100 fps was pushing a 200 gr pill.
From everything that I have read in all the reloading manuals that I have and all the magazines that I used to take is that you are asking for problems if you try to substitute powders even if they have the same burn rate. I believe that all the manufactures use pressure barrels for their initial work ups for the loads that they give, and those barrels will sustain a lot more pressure than a regular rifle barrel ever would.
Now if you can find a load for powder X that you have then you can start to work up a load. That is the sad thing about having to buy powders in a 1 lb can minimum. I have however seen some in 1/2 lb cans but no dealer likes to stock them. This is one sad thing that us reloaders need to bear. I know that I have given away more powder than I should after I read about how great it was and then tried it and found out that I couldn't get what I wanted out of it.
In the mean time I have settled on just a few powders for all of my rifles. They give great accuracy and are near the max for velocity. One load is with RL22. I had been using IMR4831 but I started to see pressure signs on the brass so I backed the powder charge off a little. Then I tried some RL22 and found that I could surpass the velocity that I was getting with the IMR4831 with no pressure signs and this was in my .340 Weatherby with a 22" barrel.
I also found out one thing about powders and that is that they make good fertlizer for the flower beds around my home. A little bit expensive but if you can't even give them away you need to do something with them.
I am always amazed at the amount of scent control products that exist on the market today. But they are there for a reason. Game animals have incredible noses and if you go out into the field smelling like body odor, summer sausage, gasoline and last night's Miller High Life fiasco you will probably not be punching a tag. Scent control sprays aren't cheap though. On a college student budget I had a serious need to alleviate at least some of my hunting costs. This is why I decided to...
