Need help IMR, 4198 which reloading data for 30-30?

[reo]

I have a can of IMR 4198, unopened, and guessing about 10 years old. I am reloading for the 30-30.
Lee's Modern Reloading reprinted in 2002 shows a range of 25.5 to 28gr's for a 150 grain jacketed.(37,300 CUP) My Lyman 46th edition, reprint 1984, shows a range of 20.6 to 23.5gr's for a 150 jacketed.(37,600 CUP) Would their be a problem using either load data? Anyone have any experince with 4198?

One of my older loading manuals, either NRA, or Lyman, mentioned that their results with IMR 4198 were somewhat erratic, and that they didnt recomend loads in 30-30 with it. Maybe that has changed in later years.

Most use a somewhat slower powder in 30-30.

I checked IMR's website they show a range of 21.5 to 23, with 23 gr's at 35,500 CUP. I'll stick with their load data. Anyone tried the Lee loadings. Seems like the pressure would be way beyond the range they are showing.

Reo,
Good decision! Over the years, there have been various lots of IMR4198 and H4198 that have had different burning rates. In my .30-30's, using 150 gr bullets, the max. load variance has been from 24 grs. with some lots, up to 28 grs with others to achieve the same velocity.

I am assembling 100 130gr and 100 150gr loads for my daughters to get used to their Marlins before we go hunting. I wanted to start low and work them up. My oldest was kissed by the scope on her girlfirends 270 and I wanted something light to get her over any scope anxiety.

I was having some velocity problem with 23 grs of H4198 pushing a light 110 grain rn bullet. I switched to Mag primers and this made a big difference. This load is listed as a starting load in the Lee manual.
