Do any other reloaders use IMR4198 or H4198 in their .223 reloads,or have you tried it.
I have a good bit of that powder on hand and am using it with the Hornady 55 gr BTFMJ bullet.I also have H335 but have read that H335 is dirtier in the AR. |

This should probably have been posted in the reloading forum. But yes, 4198 will work fine - particularly with 45-55 gr heads. Burn rate is a bit faster than optimal, so It is not a powder with which you should try to maximize velocity. Port pressure will be less vs something like 4895 or H335. Even so, most guns will cycle such loads.
But there is nothing whatsoever wrong with H335 in the 5.56. It is easily my favorite powder for near maximum loads with 55 gr heads. Goes like 4895 in the garand, 231 in the 45ACP, butter on peas, and sprinkles on ice cream. Sam |

I would save 4198's with 55 grain bullets for times when I'm in a pinch and use it with bullets 50 grains and lighter.
I don't know where all the opinions about one gunpowder or another shooting dirtier than the rest - they're all dirty, and as near as I can tell, the differences are thin. |

I have used it in some .223. Overall I'm pleased with it in my so far limited experience. With a 55 grain FMJ and a starting load of 19.0 grains I am getting 2650-2700fps out of an 18" Mini-14. I haven't tried it in an AR yet. Its economical given its somewhat lower charge weights than a lot of .223 powders and since I'm not going for hyper velocity, just a reliable reasonably accurate load, it meets my needs nicely.

Quoted:
H4198 Works really great if you guys ever get a .45-70 or .450 Marlin.  Don't forget .444 Marlin. I use it to load for my .45-70 and .444, its an added bonus that it works for the poodleshooter as well. With a mid-range charge in my .444 I'm consistently hitting 2000fps with a 300 grain XTP. I load more sedate loads in .45-70, not wanting to push that 405 grain bullet nearly as fast. I'm happy with 1300fps or so there, though the cartridge, rifle, and powder is capable of a lot more, I'm not sure that my shoulder is interested in the experience. |
