Home Forums Reloading Big Game Rifles Reduced loads using 4198

Is there a place on the web where such loads are published by Sierra or similar company?

Curious how far up or down I can go.

For instance I am working on a 260 Remington deer load and I see a 140 with 30 grains would get me 2300 ish fps.

I would like to use a 123 grain sst, wondering if 32 or 35 ish is where I need to be?

Can’t really give an answer for your .260 Rem …..but, I’ve used 4198 (with a filler) for cast bullet loads in 375 AI and .338 Win. But, are loaded pretty lightly….less than 1600 fps. I used the filler to help with burn consistency! memtb

I know it's used in some reduced recoil factory loads too. Somewhere in the 30 to 35 grain range if I recall correctly.

I haven't seen them published but I believe Seafire has provided some loads for 4198. Hopefully he will chime in since I'm interested too.

Some of the IMR data includes 4198 but not for 260 Rem.

Well the 308 and 7mm08 and etc...you'd think if it worked for one it would be fine in all of them...same case

You should consider the ratio of the size of the bottle to the hole in the end. Note how the optimum powders for the 243 are quite different than those for the 358 Winchester.

True. I wasn't engaging my brain.

I don't know much about Gordon's Reloading Tool but I have been playing a little with it. It shows 31 grains giving 2600 fps. More than 31 grains has warnings about pressure.

Hm. Ok

I was at 32 grains. Guess I better back off.

The old Speer Manuals have just what you are looking for...like #6,#7,#8,#9. Every cartridge has a reduced load with a suitable charge, real world powder (frequently 4198) and real world hunting bullets. When in doubt you can google "The Load" by CE Harris.

hodgdon publishes reduced loads for H4895 which i have used for kids many times. However, if you only have 4198 I don't suppose that will help you any.

Was shooting my 45-70 a bunch and the recoil was starting to make me flinch, i had some 4198, in my powder safe, , i would load a couple of rnds and shoot them of my man cave porch, and i kept reducing powder, until i had a manageable load, very little recoil, then chrno-ed it, it's doing 1380fps, and kills the hell out of pigs. 50 grs. H-4198 is the cat's ass in my 45-70 Rio7

I use H 4895 for reduced loads, didn’t know about 4198.

I want to say I went up as high as 31gr with 110/120gr 7mm-08 loads, but I don't have my data in front of me. It came from Hodgdon's old silhouette handgun data.

I just ordered speer number 8 from Amazon. Hopefully there will be some new info for me in there. They seem to recommend different powders than Hornady and nosler and hodgdon, which I already have

Years ago, in one of the Hodgdon Annual Reloading manuals. There was an article called "The Right Start". It used the IMR 4198 in several cartridges. "Hodgdon's 2009 Annual RELOADING "

I's suggest looking at this:

Watch out. I'm not saying No.8 is for sure the one with the problem, but one of the older Speer manuals had data developed with incorrect calibration of the copper slugs for the pressure gun. As a result some rather hot loads were published.

I wouldn't use any fillers. The small gain in accuracy with light loads is offset by the increased potential for ringing a chamber.
