Equal the H4198

I use the Hodgdon data to reload all my different rounds. I recently bought reloading equipment for my son-in-law and grandsons to reload the .45-70 for Ohio deer hunting. The IMR 4198 with a minimum charge of 53.7 grs under a 300 gr. CT Nosler RN generates around 3400 ft.lbs. of muzzle energy and really puts the Hornady Leverevoltion to shame.

This powder is one of the best that I have used I have been reloading for about 13 years now and I have relied on this powder for most of my rifle bullets needs. I highly recommend this powder and fully recommend this company.

Have not got a chance to shoot this powder yet but I do have a bunch of charges weighed up and I must say while weighting it out the consistency of the powder looks great.

Good stuff

This powder works great for my 45/70 gov, loads. It's a very versatile powder with many applications. I only wish it was more ready available. I always grab what I can when I see it for sale. Keep up the good work IMR.

shooting my 38-55 with lead bullets, 255 gr. , I found that after trying 3 powder choices that 4198 was very accurate and very very clean shooting. I was down to the bottom of the can of my old supply and was very happy to be able to get a new supply from you. THANKS FOR THE GREAT PRODUCT AND SERVICE.

I used it to reload 223 in a ar-15 pistol with a 7.5 in barrel this product did exactly what I wanted it to do it was accurate and velocities were right where I wanted them to be 2200 FPS with a 55 gr bullet this may not be rifle velocity you want but it is good in short barrel ar pistols

IMR 4198 for Marlin 1895 Trapper

I tried AA 5744 and Hodgdon 322 under Hornady 300gr JHP and just couldn't get decent groupings consistently, despite hand weighing every charge. I tried some 4198 and can shoot clover leafs at 50 yards (with XS sights even !) All this guy needs for brush hunting deer in Maine !

I found the IMR 4198 powder is the most accurate powder for my 7.62 x 39 loads. This powder works well in both semi-auto and bolt action rifles. I like these loads for shooting hogs out to 200 yards, these are head shots. The hogs are dead before they hit the ground. A very fun round to shot and easy for my daughter to handle. I'm waiting for it to come back into stock.

I purchased this powder to reload 45-70 for my sharps rifle, I don’t load them to hot as I want something enjoyable to shoot all afternoon target shooting. I keep my muzzle velocity down around 1282 FPS. I found this powder to burn clean an not much residue left in the barrel, I really like it. Will buy more when it’s available.

I use this powder in my Grendel load development with great success. I would certainly recommend it to others for its consistency. Does not meter well from my XL650, but I check every charge by hand anyway.
