for examples...........243win, 260rem, 6dash, 308win, 338fed and so on using small rifle primers is there a preference on using small standard vs small mag for best ignition, performance and reliability with case capacity between 30 and 50 grains? these hard to find and at reasonable prices has me wondering if needing to buy srp's in these type cartridges? while i do have a fair amount on large rifle primers i don't want to rely on the future of what might be available 1, 2 or 3 years from now. i don't shoot in below 50* temps much, so that's not an issue to be withstanding. reloading for 11 cartridges that use large rp's can dwindle stock at a good speed, especially when shooting more than 1 or 2 different bullet weights per cartridge and more than 1 (and up to 6) rifles in that same cartridge. 'd rather hold off on shooting as much than buying factory ammo at ridiculous prices. for that i can buy 500-1,000 cases per cartridge for 1/3 or more the price of factory ammo of the same amount. not sure on what too expect with small pockets in cases with afore mentioned capacities? any and all info would be appreciated!
