Brad,

I tend toward the conservative side as well, but hate to leave free velocity on the table if accuracy doesn't degrade.

I'll be shooting her out to 200 and beyond over the next few months.

I definitely think you did. I had a Montana in .280AI and could not get it even close to MOA. The best it ever did was with 160 grain partitions and 7828 ... and it wasn't very good.

It pissed me off. It went away.

Funny thing....with this rifle most groups with that load are single digits for ES and SD. When the numbers jump to double digits the groups tighten to well sub .5 MOA.

That's pretty darn good, for sure. Only time I ever got single digit ES numbers was with Fed Match Grade primers. It was very interesting seeing how the ES and SD shrunk significantly when going from a 210 or 215 to the Match version of the same primers with no other change in the load.

I've been getting an itch for an 84L in 280ai. This isn't helping!

Last update.

Shot today at 57 degrees.

61.5gr with new brass .936 at 200 yards. Average velocity 3076.


61.5gr with 1x brass (used brass from previous 61.5 load, primer pockets as tight as new) 1.21 at 200 yards. Average velocity 3059.

No signs of pressure.

I'm satisfied.

It's too bad those 84s don't shoot, eh!?

H4831sc...
140 160 Accubonds
cci 200

20 rounds into A INCH at 150... All day long

Stick some Remington 140 grain- 280's in the rifle and make your own brass..

neck size only- case's will not stretch, use a redding competition die seat off the lands 10 or 15 thousand...

The best brass is Norma 280- fire form with 120 grain hornady's and a fast powder min charge weight load. imr 4198 is best- jam the bullet into the lands..

Best rifle round period..

You will never trim brass again- after 15 shots per case I retire them just to be safe- I have never had a case fail in this rifle...

I have a 1:10 twist PAC-nor SS competition, 24 inch, fluted #4 on a Remington 700 action which started life as a 30-06..

2 lb trigger, glass bedded Bell and Carlson stock..

Enjoy your 280 ackley and welcome to the club...

IMR 7977 is working very well also but H4831sc is the holy grail for my rifle... It will drop anything you shoot with it- one round is all it takes and the 160 grain is a hammer of Thor on elk...

I believe the 280 Ackley is the most performance that works in a 6-6.5# rifle. The bestest mostest for that weight. I want one.

Last week I ordered a Ti 700 clone. Add a Proof 22" barrel. Hummm!

Will second that and add that I am sure I wouldn't want anymore performance in a 6# rifle...

Appreciate the RL26 info, Gents. Looks interesting--like a candidate for the 280 case as well...

NYrifleman,
How did you come up with your starting load? I found a pound of RL26 that I would like to try with 160s ABs and 162 ELD. Accurate with IMR4831 but could always do better. If RL26 burns about like R22 and is temp stable this might do it.

I think I might need to purchase quickload.

The Nosler Manual lists a max load of 61.5 with the 160 Accubond and IMR7828.

There were also threads on LRH which worked up to 61.0 RL26 and the 160 Accubond.

After reading the thread on the 270 and the 150 Partition I decided to begin with 59.0 RL26 and work up from there.

The 59.0 and 59.5 loads were anemic. The rest are published above.

The 61.5 load is a shooting SOB in my rifle.
