I've got a rifle in 250 Ackley and plan on using the data to work up loads for it. The rifle was built for 120gn bullets and won't feed the 100 grain ones.

You have a 250 Ackley or 257 Ackley?
I shot IMR4831 in the only Roberts I had (700 short action) with the 120gr Partition. It made around 2,850fps from a 22" barrel and was a fine killer on deer.

Because they hit the magazine before the point rises for the push feed.

I have a 250AI, I plan to use the 257Rob loads as a minimum load to start on 250AI.

Hodgen H4895 Actually I've regularly used all the powders that you have listed.. wouldn't question any of them, except H 4895, and that is only because of my prejudice for it, while I know others feel they have good luck with it... maybe what they consider accurate, doesn't meet my standards, or just me and H 4895 don't get along... I'd say with the above list, you COULDN'T make a bad choice....

… The rifle was built for 120gn bullets and won't feed the 100 grain ones… Bullet weight has little to do with feeding, bullet shape and seating depth do. Is the OP looking for highest velocities, best accuracy, or what? Reloder 7 and IMR4198 are pretty fast for decent velocities with 120s in a .250AI. Sierra doesn’t list anything faster than H4895. .

The lighter bullets are shorter. In order to get the 109 grain bullets to feed, the were barely in the neck. 120 grain feeds good and suits the rifling rate.

My 257 Roberts model 70 24 inch with 115gr Nosler partitions, likes RL17, RL23, Norma MRP and RL26. The last 3 give over 3100 FPS.
I do think my barrel is fast. Mostly I shoot RL23 as it is temperature stable and very accurate. RL26 will give 75 to 100 fps more but a little less accurate.
MRP is in-between a little faster than RL23 and a little more accurate. But not temperature stable.

IN my Roberts I'm shooting 43.5 grains of RL 19 with the 115g Nosler BT or the 117g Hornady interlock.

75 gr. using H4895 100 gr., 110 gr., 115 gr., & 120 gr. using H4350
It's you and the bullet, and all the rest is secondary.
