[QUOTE="sun, post: 4980383, member: 8678"] I posted the information to provide a basis for comparison and some overall perspective about its burn rate. 4198 can be used in both the .45-70 Government and .50-70 which were originally black powder cartridges used in many antique guns that were loaded with 70 grains of black powder. Some of these antique guns were trap doors that were converted from civil war era .58 percussion muzzle loaders to .50-70, the parent cartridge of the ,45-70. "The predecessor to the .45-70 was the .50-70-450 cartridge, adopted in 1866 and used until 1873 in a variety of rifles, many of them were percussion rifled muskets converted to trapdoor action breechloaders...." [URL unfurl="true"]https://en.wikipedia.org/wiki/.45-70[/URL] You can see what these military conversion looked like here: [URL unfurl="true"]https://www.cartridgecollector.net/45-70-government[/URL] And it's interesting to note that IMR 4198 is also used in one of the only published loads for the .50-70. A lot of BPCR shooters load their .50-70 with 4198 as there are very few other smokeless powder loads for it. "The only published smokeless 50-70 loads I've found using the Lyman 515141 call for 30 grs 4198 or 26.5 grs SR 4759, both using a Dacron over powder wad" --->>> [URL]http://www.shilohrifle.com/forums/viewtopic.php?t=9485[/URL] My point is that these antique guns being used with 4198 loads are not made with the quality 4140 steel that is used to make some of the modern inline barrels. The quality of barrel construction needs to be considered as well as the pressure being produced by the specific load in order to determine whether a load is safe or unsafe. [/QUOTE]
