Imr 4198

WisconsinDave · May 1, 2005, 05:25 PM

Does anybody use IMR 4198 in a .22-250, 6.5 x 55 Swede Mauser or 7 x 57 Mauser loads ? I have about two pounds of IMR 4198 that I got when I purchased all my reloading equipment in a package deal. I'm trying to find a use for it, in a caliber that I reload currently. None of the books I have mention the IMR 4198 powder in any of the above noted calibers. From what I read about the powder, it is used for light to medium sized rifle cartridges, I would think that the calibers I have listed would be fine for this powder. Since I have only been reloading for just under a year I don't want to start experimenting on my own yet.

Thanks for any Info in advance

Intrestin' question, Dave! Made me go to the books and caused my memory to function accutely. Goodnews/Badnews: My 2 most trusted sources, Lyman 46 and Speer 11, Don't show much and I expected to find 6.5 x 55 data because they disagree on burn rate selection in it vs. SPEER. What SPEER does show is reduced data for the 7 x 57 with 4198. In 22-250 and the Swede they use SR-4759 and it made me remember a few years back that IMR put out an awareness campaign regarding proper powders for reduced loads and started furnishing this type of data with each can of powder and can no doubt help you because I don't think they limited 4198 to just the 7 x 57 for this purpose, but used it for just about everything. It is a very fast Rifle powder with only a few ahead of it in burn rate. Probably not exactly what you wanted to hear and maybe someone can help with actual use. Looks to me like you could burn it for reduced loads and lower velocity hard cast loads like the Oregon Trail Bullets.

Best suited to smaller cartridges like the 222REM, the 223REM plus the bigger straight walled cartridges like the 444MARLIN and the 45/70GOVT. You have found no data for the cartridges you mentioned because IMR4198 is NOT well suited to any of them. So, you got two pounds of it, huh...sounds like a great excuse to buy a new 45/70 rifle to me.

Good answer Terry.....never thought of that. I'm always looking for a good excuse to buy a firearm.

IMR 4198 and IMR 4895 are my best powders for .45-70 and cast bullets in .243 and .303 Savage, a lot of velocity with not much powder.

An ancient Dupont gimme booklet shows max charges of IMR 4198 in the 7x57 as follows:

130 grain 29.0 2365 fps
145 29.0 2260
160 28.5 2135

Same booklet shows 27.5 grains under a 120 in a .257 Roberts. That's enough info so I would be willing to use 26.0 grains of IMR 4198 under a 120 grain bullet in the 6.5x55 as a starting load.
