I bought a Savage Ultralight 280 Ackley and will be starting some test loads. What's your go to loads?

Got rid of mine quite a few years ago. From memory, though, I think 60.5 grains of 7828 with 160 grain accubonds. You should compare that to Nosler data, don't just trust my memory for safety.

RL 26 at 61.5-62.0 gn with any of three different 150's is a very pleasant spot in my Kimber.

H4831SC and RL22 have also been very good, just not quite as good as the RL26.

63.5 VV N165 with 140 AB’S runs right at 3200 in my 23” barreled Borden Timberline and cuts the same hole.

H1000 with a 160gr Sierra GameKing hollow point and H4831sc with the 150gr ELD-X have been the death of several WV whitetail the past few years..

I've also developed good loads with RL23, IMR7828, IMR 4831, and IMR 4350 with bullets ranging from 120 to 154gr

162Eld-X/IMR7977
143HH/H4831sc

Kimber Mountain Ascent, 60 gr. R-26, 150 gr. TTSX's for 3050 fps.

H4831sc and the 154 grain Interlock. If you are interested, I’ll share the charge, but I’m not in front of my notes. This combo is consistently sub MOA in my Kimber M84L.

63.5 RL22. 139 LRX

RL17 and 120's have been great killers, sub MOA.

H4831sc and 160 accubonds at 2930 fps

RL 26 & 160 Gr, Nosler AB, Peterson brass, 60.5 GR, CCI 200 24" LH Forbes 2923 FPS

Like the 2 above good results with the 160 AB and 162 ELDX using Rl26 and H4831sc. 2933 FPS with the 4831sc and 3023 with the RL26.

Rl 26 and 160 accubonds
H4831sc and 145 LRXs

Both are consistently sub .75moa in my kimber montana with a variety of charges.

What’s your opinion on your 7828 loads?

Mine is IMR 7828 and 140 NBT, right at 3100 FPS

55g of RL 16 and 145 LRX.

rl22 over 140 ab

H4350 and 150TTSX.

The 7828 is decent depending on my bullet chosen, but no matter what bullet I've tried, the 7828 is usually not the most accurate. H4831SC, RL23, and H1000 have outshot the 7828, but it's certainly useful and the speeds gained are great.

Yeah, it’s fast for sure.

55 grains of H4350 behind a 150eldx @3,046fps. Really tight groups and kills red deer well.

Thanks for the replies.

This is the load I settled on except that I used the 140gr VLD-H

I love my 280 AI! My rifle has a 1-10" twist rate and does better with lighter bullets. These two have been standouts for me:

140 gr AB - has been my go to load for pronghorn and mule deer.
59.0 gr RL-16
3200 ft/sec

150 gr TTSX - effective elk round.
56.0 gr RL-16
3070 ft/sec

IMR7828 has been my go-to powder paired with Noslers 160 grain Partition. In my rifle, 60 grains produced about 2950 FPS and great accuracy. I've taken elk, mule deer, and antelope with that load.

A 160 at or near 3000 is a do-all load.

Hicountry, what charge weight are you using with the rl26? With Petersen brass I am topping out at around 61.5gr.

stumbled on a 139gr interlock over 55gr of H100V as a fantastically accurate load in my Montana while looking for something easy shooting that happened to use a powder I had on the shelf with no use for.

Will also be working up a load with the 145LRX shortly. Anyone used IMR 4451 or 4955 with the 145 LRX?
