Thanks NYrifle. Will give it a whirl.
Thinking that this powder might work well with the new 300 WM that is on the way too.

I'd try it with the 200 grain heavies in the .300 Win. I wonder how it would perform with the 200 Partition.

No signs of pressure.

I'm satisfied.



Yep, you're done.

Congrats on the nice combo.

RL-26 61.5 grains
3,050 average


Barnes 145 LRX
RL-26 63.5

Sadly, I'm not getting anywhere near that velocity out of my 7 SAUM with RL26 with 160 grain Accubonds.

Now you've got me thinking.

I've been working with an .300 Win M-70 Classic Stainless, 24" barrel.

And I have a pile of 200 grain Partitions on the shelf. wink

From SnipersHide

"I have used 70 gr r-26 in my 300 wm and am able to get 3035 with the 215 hybrids. I got up to 3080ish with heavier bolt lift and an ejector swipe. I am seated out to 3.710 oal length roughly or 2.95 to the ogive. Same powder charge of h1000 got me 2950ish. I was able to get it down to an es of 18 with a ad of 8 which I think is good enough for the sendero sf ii for me.I have shot a .4 group at best but usually am around .6ish. With about a 3.25 in group at 560. Haven't been able to take it farther yet.The speeds were taken with a magneto speed. I don't use quick load to know what pressure I'm running but I have 3 reloads in nosler brass and all primer pockets are still tight with no bulge above the belt."

He's using a longer mag box. Partitions have a shorter bearing surface I'd assume? Start around 68.0 and work up from there?

I would bet on Partitions having a longer bearing surface than a Hybrid and would probably start lower than that.

Sounds like a nice combo in your 280 AI Montana. That rifle makes a lot of sense.

The 280 is an outstanding round. I had a Model 700 re-barrel with a match grade stainless 24" # 4, Fluted Pac-Nor, 1-10 twist- 3 years ago...
The Action lug and first inch of barrel shank is glass bedded into a Aluminum action based Bell and Carson Stock...

To date I have fired an estimated 980 rounds...

6 deer 7 hogs- one shot DRT Kills- 87 to 328 yard shot's... Scope is a Luepode 2x12x42 VI ..

The Rifle shoot's sub .5", 5 round groups all day at 150 yards with Sierra's, Nosler's or Hornady's with H4831SC...

I once shot a 35 round string into 1.1 inch at 150 yards- opened vertically a bit, due to a very gusty tail wind...

140's average is 3180 fps
150's average is 2990 fps
160's average is 2905 fps

Could load these hotter- but why?

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...

Awesome!


I think the totality of the awesomeness is lost on most here.

Best rifle round period!!
