I was going to start a topic on this and on bullets also. One quarter pound of powder and 25 bullets will tell you whether you like that particular one. Set it back with all of the data that one can think of when doing the reload. The whole 9.05 yards of it. Temp, humidity when loaded. Same when shot. Cartridge length then OAL, looking good on that one. Get same powder or bullet weight check it out. Then finish it on out for that particular gun. Then see if it works in the bolt action as it did in the slide/semi-auto etc.
I quit reloading several years ago and I cannot find but very little of my data on the .38, .357, .22 Hornet, .223, 22-250 .243, .270, 30-06, 7.62x39 and then this year I acquired a 7.65 Belgium Mauser (don't understand why but this caliber only has recommendations for 3 bullets, 150, 174 and 180 & the Net is short on it also because that is where I found the loads for that rifle. Wonder if the One Book - One Caliber to see if there are any lighter heavier loads recommended for it) and the 7.65 Russian. Found 2 of them for $80. One is 100%bluing 95% bore, 75% wood other a 90% bore, no bluing, 50-60% wood. Just couldnt turn 'em down. Got more guns than I can shoot of an afternoon at the range anyways.
Take care
God bless
When I was doing my reloading, I had some charts showing density of powders and I had worked my loads up by using density of powder so I could get about 70%+/- of case being full. Anyone out there know where to find this on the internet. I had got this list from a gun sales/repairs store that eventually went out of business when KMart started handling the basic RemWinSav in their lineup. D&D Guns had the repairs and sales of the other calibers of guns. Bad to see them go.
As for as the topic goes, I will buy powder by the 1/4lb. And would buy bullets in the 25 ct box. I dont' see where that will increase the amount that they would sell the 50 or 100 bullet/box. One will certainly have some extra money spent ahead of getting into the reloading of that "favorite, honey" round.
I bought 500 Remington bulk, 30cal for one of my guns and because that gun likes that particular bullet, remember this one from a long time ago but currently working up a powder for the solution for the "favorite" round. I am pretty certain it was an IMR because I used mainly that brand because of workups I did.
