257 AI -powder suggestions & Brass

All, I have a 257AI that loves AA3100, sadly I am down to my last 1.5 lbs ! Has anyone found a replacement for 3100? I am using 110 gr ABs?
Also anyone use Nosler +P brass to blow out for the 257AI and have comments? I have been using R-P 257 brass with good results, the prep work is tedious !!

I'd really give a look at RL26 if you can find it, I bet it is a SCREAMER in your Ackley.

Nosler brass should be excellent for what you wanna do.

I used Remington brass/ IMR 4350/Hornady 120HP in my one and only 257AI. It was a long time ago, but both the brand of the brass and the IMR 4350 work great together. I'm sure one of the newer powders would be worth playing with.

I second the RL26. :grin:

If you can't find RL26 I would look at Norma MRP. I use it in my 257 Bob with stellar results. 2yrs ago I was looking for RL26 an I couldn't find any, found a 8lber of MRP on clearance at Sportsmans Whse and have been very happy with it. works awesome in my 270 Win also
Take care

Where are you "257 Ackley"? He would know....Haven't seen or heard from him in a long time. CL
