The Original Lumpy Gritz Posted July 5, 2020 Share Posted July 5, 2020 Outstanding, thank you I don't see any data for .38 Special. Also, shows low end .44 magnum loads using Unique. See no data in the .44 Special section with Unique. OLG Link to comment Share on other sites More sharing options...
Cheatin Charlie Posted July 5, 2020 Share Posted July 5, 2020 John Boy do you distance group size was measured for all calibers? Or did I miss it? Link to comment Share on other sites More sharing options...
Sedalia Dave Posted July 5, 2020 Share Posted July 5, 2020 I strongly suggest reading this. "The Use of Pistol Powders in Rifle Cartridges" Written by the same people that developed that data. Link to comment Share on other sites More sharing options...
John Boy Posted July 5, 2020 Author Share Posted July 5, 2020 Grits, can’t win them all. In the FAQ there is plenty of reloading data for the 38 Spl and 44 Spl. All folks have to do is LOOK Link to comment Share on other sites More sharing options...
John Boy Posted July 5, 2020 Author Share Posted July 5, 2020 Charlie ... no trajectory distances in the reloading data. But you can put the reload data provided into a trajectory calculation table for any distance range you plan to shoot. I plan to do this with a new 300 Win Mag I have not shot yet There are several free trajectory tables on the Internet Link to comment Share on other sites More sharing options...

John Boy Posted July 5, 2020 Author Share Posted July 5, 2020 Dave, that is one hell of an excellent write up and should be read by CAS folks for specific do and don’t use before they make severe mistakes reloading their firearms. Phil Sharpes is mentioned extensively in the article. I reload for many pre 1900 calibers and Phil’s book is the first one I go too for the proper reload. Also in the article, burn rate is not the only information determining which powder to use Link to comment Share on other sites More sharing options...

John Boy Posted July 6, 2020 Author Share Posted July 6, 2020 Quote do you distance group size was measured for all calibers? Charlie - I looked again at the tables and GS I presume = Group Spread in inches for all the powder weights/bullet weight Link to comment Share on other sites More sharing options...

If you click on the cartridge instead of the bullet weight it gives more info about the test and other things. Fire Arm Barrel Twist Optics Distance Shots : Marlin 1895 : 22 inches : 1:20 inches (micro-groove) : 24 X : 50 yards : 10 Click on figure to access ANSI technical cartridge drawing In 1873 the U.S. military adopted for standard issue, the Springfield "Trap Door" single shot rifle, chambered in 45-70. The 45-70 remained the military's official cartridge until replaced by the 30-40 Krag in 1892. Although after that it was nolonger an official cartridge, for some time it remained popular. By the end 1930's most American firearm companies ceased chambering the round. Since then a solid, sustained following has developed. Today (as of this writing, 1998) Marlin chambers the 45-70 in their model 1895, Ruger offers it in their #1. With the advent of "cowboy" shooting, many companies have begun offering High Wall or Rolling Block era reproductions. Although the 45-70 is a viable short range deer to grizzly bear hunting cartridge, to most today, the 45-70 is a target cartridge. When adopted in 1873, the standard load was the "45/70/500" - a .458 calibre bullet, weighting 500 grains, sitting on 70 grains of Fg black powder, generating 1320 fps at the muzzle. Later the standard load was modified to "45/70/405", generating 1460 fps. As a target round, with a 405 grain bullet, the 45-70 is viable out to 1000 yards. Great care MUST be exercised with regards to 45-70 loads and the firearm in which they're to be shot. Trapdoor reproductions must be limited to 18000-20000 CUP or less, the Marlin model 1895 will handle the ANSI standard maximum pressure, 28000 CUP. Only the Ruger #1 can be loaded to 35000 CUP. Shooting a maximum Ruger or Marlin load in a Trap Door class firearm, will result in the DESTRUCTION of the firearm and SEVERE DAMAGE to the shooter. Care MUST be exercised in load selection Link to comment Share on other sites More sharing options...
