New 280 Ackley Christensen Ridgeline load data

[jnm300ultra]

Hi all, looking for some load data for the 280 Ackley. I have 100 pieces of Nosler brass and 50 Nosler 150 grain Etips. Also maybe some info for the Barnes 145 grain LRX, and the Berger 168 grain hybrid. I live in California and it’s the only reason I’m trying the lead free bullets. The Berger is what I want to see what you he rifle is capable of. Any info on the seating depth would help. I heard about the seating depth for lead free ammo is always a long jump. I tried some ETIPS in 6.5 120 grain in the my Nosler 6.5-284 they sucked 1 1/2 -2” groups at 100.
Thanks
Jason

You ever find anything on this?
I just bought one..

I tried Rx22 with 160 and 162 grain bullets, but did not get great results on the groups...I finally settled for H4831 and 140 grain Accubonds...the H4831 grouped well with the heavier bullets, but the velocity was down about 100fps from Rx22 and IMR7828.

Thx for the note. I picked up some 145 LRX, I’ve got some Ramshot hunter I was gonna try:

 

[Cloudchaser]

I did shoot some 168 gr.Bergers, but did not get great groups...around 2 inches with Rx22, IMR7828....If speed is not an issue I would shoot the H4831. I wanted to try Rx26, but cannot find any starting loads for it.

I’m shooting the 145LRX with Reloader 23 .
60.3grns was charge weight …. Went up to 60.9 ( compressed ) in RWS brass .
I also have Peterson but haven’t tested yet .

Good to know.. What were your results speed and accuracy?

 

[Ackley Kid]

Accuracy was very good . Only tested at 100yards . Node went from 60.1 -60.7 .
@ 60.3 grns was getting 3200FPS from 26” barrel 1-8.5 twist

Very nice. What kinda rifle?

 

[Ackley Kid]

Rifle is on defiance tenacity action , IBI barrel , greyboe terrain stock , trigger tech special. Worked out well for a hunting rifle .
Componets are pretty scarce in Canada right now so never got to test heavier weights .

I shoot IMR 7828 with fed 210's, 175g Nosler LRAB, get small groups, bullets opening up a hole, 27" X caliber 9T, #5 taper with Gentry muzzle break, Rem 700.

Use the IMR 7828 with amazing results with 160g also in std 280 Rem, 2930 fps with 160g Partitions, Fed 210, 24" Rem 700 RS. The load is listed in the Nosler manual #4. 160g Sierra BTSP is an amazing deer killer.

I’m using 58 gr IMR 4350 with 162 AMax out of a 28” 8.5 twist pushing to about 2830 fps- depending on temps, I can get .4 to .5“ groups at 100 yds if I’m doing my part.

 

[AthlonOpticsGuy]

Mine likes about 58 grains of RL23.. Got .588 groups in the wind at 100. Velocity is 3086 pushing the 145 grain LRX bullet. Shoots flat and straight!

 

[LeeMiller24]

I’d like to do a 175gr ELD-X or same size and push it in the neighborhood of 2900 fps. I’ve got 4831SSC - anyone have any suggestions on this?

280 AI, Hart 26" #3 I used H4831SC with OK results. But someone on here suggested i give IMR 7828SSC a try once and the groups shrunk almost by 1/4 at 600 yards. Went from just under 6" gun for three shots ( its a light weight hunting rifle) down to just a tiny over 3" in fact I shot one group that will never be reproduced as it was pure luck of 1 1/2" at 600 yards.. Thanks for the advice on IMR 7828SSC. Seems like my rifle really likes it with the 162gr Hornady and 180 Berger.
