Good to know it works in the t97. I use 25gr h335 under a hornady 55 fmjbt, way more accurate than the cases of norc yellow box I have...
The h335 meters very well in my lee discs. How is the d4198 for metering? Is it an extruded stick type?
What kind of loading do you use for 308 with 4198. I have not been able to find any data on that.

Some yars ago I used IMR4198 in the 308 with 150gr bullets to make reduced hunting loads for a young hunter.
35gr IMR4198 was about 80% load density and 2500 fps.
Thanks jethunter, where did you get this data btw? From my searches 4198 is not well suited for heavy 308 bullets, but i have seen mentions of its being used in sbrs and reduced loads. I will have to try it for myself, just need to verify for safety sakes.
There are powders much better suited than 4198 for wringing max velocity from a 308, which is why you don't see it listed in 308 load data. If you can live with a bit less velocity then 4198 works well.
I used Quickload and a chrony to develop this load. If you want some feel-good verification call Hodgdon - I've done that when I wanted to verify a starting point on a powder they didn't list for a cartridge. They use Quickload, too.![]()
QL says this load is 45K, basically a clean starting load. I tend to have confidence in this pressure estimate because the velocity was right on, and lighter loads had a few sooty necks. Sooty necks start to go away when you get over 40-45K psi range.
I did load some warmer loads as well for testing but the 35gr load was exactly what I wanted so that's where I settled.
. Thanks!Thanks for sharing. What I need is just some 100-200 yards bolt action target rounds. So would your loads work with the 147gr Campro bullets? I am pretty new to reloading, so anything would help
. Thanks!
