I am doing load development with my 280AI. Using IMR 7828ssc with a Berger 150 gr Classic Hunter bullet. I also have 168gr Classic Hunter bullets to. But kind looking for data with the 150gr. I have several boxes to play around with. Is seating depth as picky on them like the VLD bullets are? Like to know how they preform on game to. Wanting to use on a spring black bear hunt. In Montana or Idaho hopefully. Hoping to get the 7828ssc to work in my rifle. Shooting a Xbolt Speed Long Range 280AI 1@8 26-inch barrel. I just picked up several more cans of IMR 7828ssc. The velocity is little high than some of the other powders. But the accuracy has to be there to. Going to keep the shots under 500 yds. That's why I was wondering about the Classic Hunter bullets.

I shoot 7828 long cut in both the std and AI. Accuracy with both is best with Federal 210 primers with loads at max for the rifle in the std and darn near that with the AI. I am shooting 160-162g in the std., and the 175s of various types in the AI.

I am using new nosler brass.(Cant find any Peterson brass.) Federal 210 match primers. Never shot any of the Classic Hunter bullets before. Later on i'm going to play around with some ELD bullets. In X 175gr and M 180gr weight. And some Berger 175 gr Elite Hunter bullets.

Peterson just did a run. They can tell you where it's available.

IMR 7828ssc is a very good powder choice for the .280AI and you're fortunate to have plenty to develop a load. It is scarce these days. Velocity should not be a problem. Keep us posted on your load development.
I went and bought the last 2 cans locally. It was 51.99 a can. They had 2 cans of Ramshot Grand powder. I thought i would grab them to try out. Until I seen the price 75.99 a can. I put them back. If I cant get the 7828ssc to work with 150 or 168gr Classic Hunter bullets. I always have ELD in 175 and 180 bullets. Also want to try Berger EH 175 gr bullets sometime. But I think I can get the 150 gr bullets to work.

Most all bullets are picky on seating depth. Thats just the way it is. With the lighter bullets 7828 might be a little slow. Id look more at the 4831 burn rate. I had a lot of luck with RL23 and 168vlds. Very accurate.
7828 sc is the most accurate powder for my 280 Rems and 280 ai rifles. The ONLY reason I switched is for temp stability.
With bullets ranging from 160g to 175g it has been superb.
I hunt anywhere from 80 degrees to near zero.

I hunt in Arkansas so the weather is crazy. By Nosler reloading data. With a 150 gr with IMR 7828ssc .
63 gr max 3107 fps
H4831SC
60.5 gr max 2995 fps
First one is Nosler.
Second one is Berger.

I've been using IMR 7828 for years in my 280 AI with 160 accubond with great results.
Work up to pressure when it's warm out and drop it off a grain and you'll be fine.

I sure wish they would produce more of 7828 along with IMR4831!
