over 34.5 in a 30 br.

It's there...provided you can get the powder in the case. But there's ways to accomplish that. What gets in the way is the practicality of doing that in a tournament setting when you're loading between relays. Of course, where the base of the bullet ends up in the neck matters more than a little. The 'long neck' 30BRs (1.540-ish) give a little extra volume over the 1.500-ish versions.
In the past, my solution for more 4198 in a 30BR case was the 30BRX.
Honestly, there are several powders out there that are worth exploring when we look at load density relative to charge weight. Work in that area could prove worthwhile

35.0+++ load density:

I have an insert in the bottom of my drop tube with a small diameter opening. This slows the powder enough so it really packs in the case nicely. It's like using a long drop tube but a lot less cumbersome.
You can also stretch out a spring and put it in the drop tube...the powder swirls around the spring and slows down before it drops into the case. -Al

Sneaky. I like it.

Is 31.2 H4198 a error? At 34.5 i'm setting 1/2 way up the neck. I have been up to 34.8 with no hard bolt lift. But the accuracy didn't get any better.
ty Guys.
Something doesn't sound kosher. Your 34.5 half up the neck is pretty spot on. In all my 30BR stuff through the years (Lapua cases), 32.5 is right at the bottom of the neck.
4198 being on the edge of too slow in the 30BR, one big advantage of the 34.5+ loads is how the powder cleans up at higher charge weight. If you look, the inner case necks with the stiffer charges look a bit 'grayer' (dirt clod ballistic-speak) than the low end charges. -Al

I've been up to 35.4 gr. of H-4198 in my 30BR without a drop tube but accuracy was no better than 34.7 gr.
You can't compare case fill between H4198 and IMR4198. The IMR 'sticks' are considerably longer than Hodgden H4198. -Al

I can see that from your picture.
I've also been told that the IMR version will not work in the 30br, but dang 5 in a ragged hole, using a brand new Hart barrel sure looks pretty good to me at 100 yards.
With a little over 6 lbs. of it I'll keep using until I run out then switch over to the Vivatori powder.
I'll be starting over this coming week with a 40x Leupold because the 45 went back for factory repair yesterday.

Yes....IMR4198 can shoot very well in a 30BR. The velocity is a bit lower, is all. Sounds like it's working great for you.
