Mine is built on a pre 64 M70 action, 24" pac-nor fwt barrel.
I load 62g of RL22 and 150 barnes TTSX's @ 3050 and nice, tight groups.

If I could have only 1 powder for the various 280 based wildcats (AI, Gibbs,JRS, PDK etc)it would be RL22

My latest 7mm is a WSM in a Kimber Montana. I am loading 140gr Berger VLD's over H4350 and the book velocity is 3100 fps.

On it's last range check it put 2 shots into one inch at 200 yds with a 5-10 mph breeze.

It weighs 7# 4oz with a 3-9 Conquest.

What chamber is your 280AI, the Ackley or Nosler?

A 24" Featherweight barrel! Now that's interesting.

My 280 AI is a Rifles INC. Titanium Strata with skip fluted Lilja barrel with removable break, blind magazine stock and jewel trigger @ 2 lbs weighs 6 lbs 12 oz w/ scope.

Loading a 160 gr Barnes TSX, 62 gr IMR 7828 ...... 3025 FPS

Lex sure knows how to build a rifle!!

This year I am shooting 59.0 grs. of H4831 under 160 gr. Nosler partitions popped by Wolf Magnum primers. 23 inch barrel and hopefully getting around 2850 fps.

About a month and a half ago I got my first 280 Ackley (SAAMI) in a H.S. Precision SPL. I'm experimenting with the limited bullets available. This gun shoots.

Using 54.8 gr Hybrid V 100 and 145 gr LRX bullets it shoots 5 shot groups into less than a half inch. Using 54.1 grains of IMR 7828 and LRX 168 gars, it shoots 5 shot groups into slightly larger than half inch groups. Naturally I can't find any more of those bullets but I have the recipes. I'm experimenting with berger VLD 168s now and I think they will be in the same ballpark when I get around to finishing my testing next spring after hunting season. Until then this darling of a rifle is going back into the safe. Hope by then bullets are plentiful again.

63.5 gr VV165, CCI BR2, and a 140 Nosler Accubond has shot well in a variety of 280 AI's, not sure why but it tends to shoot universally well in most 280 AI's

Mine is a Sako L61R that I made up in 1998 with a douglas barrel.

The best load is 160 gr Nosler accubond and 59.5 gr of VV N560 - a Nosler manual load. This gives me just short of 3000 fps in a 24" barrel and very accurate.

I developed various accurate & fast loads within spec using 150 gr Rem PSPCL, Speer 145 BT, 150 gr Barnes TSX etc.

I got great results with Re19 & VV N 160 for the 150 gr bullets.

I had poor results with Re22 & AR 2213 SC (H4831SC)

My favorite 280 AI load is 60.0 gr SuperFormance pushing a 140 gr TTSX chronographed at 3057 fps. Very accurate. 60.5 gr was also v. accurate.
