Bullet construction and material composition. For example: with regular cup/core bullets Speer's give higher pressure than Sierra's and Hornady in the same caliber and weight. Not every manufacturer uses the same jacket alloy/lead core alloy.
My .375 shoots 4"-5" groups using RL15 or IMR 4064 no matter what jacketed bullet I use. IMR 4350 or H4350 will clover leaf to the point of holes touching at 100 yards with any bullet brand I've tried. Also IMR 4350 has proven very temp stable in the .375 varying less than 20 fps from 20* to 90*...
The .50 Alaskan can drive a 525gr. bullet at 1850 fps from a 22" barrel at less than 35,000 CUP. I have a Browning 1886 converted to 50-110 WCF with a 26" barrel that using .50 Alaskan load data will easily break 2000 fps with that load.
The post office closest to me WON'T cash a USPS money order. I've always found that odd. I quit using USPS money orders years ago. If someone won't take my personal check, I move on.
I don't know the exact reason but I do know that whenever there is a component shortage Alliant powders are always the most difficult to come by. I moved away from them for that exact reason.
Looking for a box or two of Speer #1629 (145gr. SP) and Hornady #2830 (154 gr. SP) flat base spitzers. Prefer to get either one of each or 2 of one from same person so shipping is worth while. Thanks, Patrick
I have an old keg of DuPont IMR 4064 from the 1970's that I use to load practice ammo for the .458 WM. With 71.0gr, a Win LRM primer, and a 500gr cast bullet it clocks 2078 fps. Switching to a CCI 200 primer the velocity drops to 2053 fps.
You have a great press to use those file trim dies on. The angle allows the filings to fall away from the ram and not down into the press body/ram interface.
I doubt it is even remotely viable. They can't make 9mm Luger or .223 dies fast enough. Just think of the backlog of the thousands (tens of thousands?) that each maker need to produce in those calibers alone. There's no reason to make 2 dozen .404 Jeffrey die sets from a business standpoint as...
I respectfully disagree with the Professor. Euro cartridges don't even remotely come close to holding their own in the the USA as far as market share or volume of guns and ammo made. The 3 exceptions are the 9mm Luger and 7.62x39mm, and the .375 H&H. Every other Euro cartridge is a...
