I need help, I’ve called or emailed a few bullet manufacturers, looked on the Hodgdon site and I’m not finding any reliable information as far as load data goes for the Berger 195s or any ~195gr bullets using IMR-8133. There’s no Retumbo, RL33, H1000 or N570 to be found and I’m surprised I found 3lbs of 8133. I just might have enough to work a load up and have some rounds to hunt with this year. If anyone has any data, (I’ll be careful), I just need somewhere to start with this stuff. I also have 3.715 of of mag length, I haven’t checked how long my throat is though, I just need to screw the barrel on and I’ll be ready to shoot.
Any help would be much appreciated.

I’ll need to look tomorrow at numbers but I ran 195’s with fed magnum primers, Bertram brass and 8133. Ran close to max length with a wyatts extended mag box bdl. 3160 out of a 27in barrel.

I have two ladder tests loaded up with IMR8133 in 28 Nosler ready to shoot this weekend. With the 184 F Open Hyb and 195 EOL. 26" 1:8" barrel, not SAAMI reamer though, throated for the 195s.
I could not find any info either, so started just below halfway per Hodgdon/IMR reloading data.
I will try and post up results this weekend.

Yeah, I was sort of thinking I’d just compare some of the other similar cartridges that have data for it and get close to what might be a starting load. I’m thinking I’d be safe starting around 76gr and could work up to possibly over 82gr-84gr somewhere. I’m thinking 84gr would give me more than 3k FPS.

Okay I don’t have the length as I sold the rifle but like I said they were seated long for the wyatts box. 83.3 with very slight pressure signs. 3160 w/27in barrel.

Contact Berger, they would give you the information you need to start if they have tested with 8133.

I never tested the 195's with 8133 in my 28, but did shoot it with the 180's, I would think, using a starting load point for the 180's would be okay. If you know someone with QL they may be able to run the numbers for you.

Yeah, I have a plan for it already. It’s funny Berger said because it’s not in QL yet they don’t have data for it.
