Does anyone have a favorite powder to load under 100gr. Partitions in the .243? I'm leaning toward 7828, but have H4831, IMR4350, RL22, and 780.
Thanks

H4831 is what I use for 100grainers.

IMR 4350 seems to group best in my 700 Rem with 9+ twist.

Dunno how many .243's I've loaded for, but so far either IMR4350 or H4350 has shot well with 100-grain bullets in every one, whether it has an 8, 9, or 10 twist. Generally around 41 grains does the job.

I've had my best results with one of the 4350's.

I currently load 100gr partitions in a couple of my 243's and have used IMR 4350 for several years with excellent accuracy. Although I think if I had to do over again, I might try some Reloader 15 or 22.

Thanks guys. Since I have 2 unopened cans of 4350, I guess I'll start with that, saving the other stuff for the .270s. Besides the NPs, I've got a bunch of Sierra PHs that I can use for practice. They have a very similar form to the NPs and a a load that's okay with the Noslers should be okay with the softer Sierras.
One good thing is that these powders can be found just about anywhere, unlike a lot of the medium burners.

The most accurate rifle I ever shot was a 243 loaded with 105gr Speers and a discontinued Winchester powder called 785. IMR4831 was the second choice when 785 was discontinued. I haven't worked with ball powders much since then (30 years ago), but if there is any "magic" in the 243/ball powder combination, I gotta believe there is one out there with characteristics similar to the old 785. Maybe 760 is close? Is MRP still around? Hopefully someone with more ball powder experience will chime in here.

Any of the 4350s. Personally, I use H4350SC and I find it to be superb.

I have some 780, which I got for loading 160 NPs in my .270 because it gives top velocities and even the starting load is plenty fast enough for almost anything. The 780 data for the .243 also looks impressive, but the stuff is pretty much impossible to find, so I'm saving it for the .270 loads. You never know when a moose or griz will pop up in WV using one of those trans- continental Bigfoot tunnels that Art Bell used to talk about!

H4350 has worked very well for me for the 95-100gr bullets. H4831 worked as well. It's hard to beat 4350 as an all around 243 powder.

Many loads do not completely fill the 243 case. With 100 grain bullets, the maximum load of old fashioned H4831 just nicely fills the case. IIRC, I get 2950 FPS with a 100 grain bullet.
Be not weary in well doing.

As long as the case is pretty full, I've not found load density to be a big deal.
I have some capable rifles that shoot little groups with charges that shake quite audibly.

I use Varget for all my .243 loads. My favorite bullet is a 95 gr. nosler and I consistently get 3/4" groups with that combination

I have a 243 that shoots best with 45.5 gr. 7828 with the 100 gr partition.

I've used powders with burn rates from 4198 to 7828 and every thing in between... ALL of my 243s have been accurate beyond what is needed for deer hunting...only real decision is what sort of velocity ya think ya need...
2600 to 3100 fps or a little more has been quite possible...with no velocity more accurate than the other...
mine are Ruger, Winchester, after market barrels and A Remington ADL...
