H4350 in a 280AI.

H4350 is indeed a great all around powder. I use it with 140 class bullets in my 280ai. Depending on your chamber throat it may be the best for case fill. Slower powders such as RL23 with longer bullets can cause compressed loads if you are dealing with a SAAMI chamber. My rifle didn't like the 162ELDM with RL23.

Mine loves the 162eldx at around 2900fps using R17, R22 or IMR 7977. Under half inch groups, but there are a lot of bad reviews on this bullet at usual whitetail ranges. I have only range shot it at this stage, having other proven game loads to use up first.
Strangely, I haven't tried H4350 with 160's yet even though it is my favourite powder overall. I will rectify that. It sure does very well with 150's though.

As others have said, the H4831 is the magic pixie dust for 280 ai, in the 160 class bullets. But the H4350 isn't far away. I developed loads with both, with the 4350 being my second choice. If I had that much H4350 powder, and I didn't have another cartridge using the 4350, I'd sure give it a try in my 280 ai.
160g Sierra btsp is magic pixie dust in the 280 and AI at 2900 + fps. The std 280 gets there with IMR 7828 Long cut with a federal 210 in multiple rifles with 24" barrels.

I do like me some 7828. I've had really good results with it in a 300winmag. Haven't seen it for sale in a while though.
R#22 and IMR 7828 are kissing cousins with the 22 liking cci 250s vs the IMR 7828 loving the fed 210s in the 280 and AI
RL16 has done great for me. I shoot the 140 accubond at 3250. Flat out hammers deer. I've yet to recover a bullet, killed a couple at 50 yards or so.
Accubonds are expensive but I get them from the nosler second store. Normally about half price.

Going back thru my records, Reloder 22 also did very well
Beaware that IMR 7828 old long cut version and the new Short cut versions have different pressure curves, the shot cut version seems to develop pressure a little sooner.

Yeah I found that out. Picked up a can locally after not having seen the regular 7828 in a long time. It said on the can that it was the same as regular 7828 but I found out real quick that wasn't the case.

7828 is magic in my 280AI with 160s. It really like H4350 with lighter bullets 140 - 150s. If I do my part it was cut 1 ragged hole with 150ABs at 100 yds.
