Home Forums Reloading Big Game Rifles 280 Rem. Loads

Send the recipe. Thanks...

Kinda curious about the recipe also.

It seems to me that JB has recommended 58.5 of H4831 under a 150 Partition in Gack. That load has worked for me, too.

I got one of these in Sep 2018. QC seems to be good. It is accurate with 150 NBT over RL23 and 210M. I would post a pic of my latest target but I have lost that capability somehow.

I have a Ruger 77 tang safety that's been in the safe unused since the late 1990s. Then I always used IMR 4350 and 160 Partitions for around 2800 FPS. This thread and a couple of others got me to wondering as to how it would perform with different powders so I started working up a load with IMR 7828 and was really surprised as to how good it worked. I had about half a box of 162 SST bullets so started with those and topped out at 57.6 grains of powder and 2920 FPS. I was working up to a Quick Load max of 58.6 grains but at that level the case head expanded .0001 inch so the load was backed off 1 grain and that was max. Also 3 shots went into a 11/16 inch group. Anyway that experiment with the different powder was a big surprise. Regards

I’ve heard good things as of late. Seems QC is improving and the Mountain Rifle gets more attention than the Wal-Mart spec 700. I’m going to order one when I get a little ahead of things.

I had best luck with IMR4831 and R17.

That's the exact same combo I'm loading at the moment. It's doing 2929 fps.

RinB, what's the best recipe using RL17? Thanks Daniel

I've only worked with the Speer 160 gr. Grand Slam bullet in my .280. Started out with IMR7828 but while I got the speed accuracy sucked big time. I have some of Winchester's long discontinued WMR and in Winchester nickel brass, WLR primer. 57.8 gr. of WMR gave 2908 FPS and .75" groups on average. I'm lucky enough to have a good supply of WMR as I use it in my .270 Win. and .300 Win. Mag. as well with excellent results. The only cartridge it doesn't work worth spit in so far is the 30-06. Even Winchester's data booklet #15 only shows data for 200 and 220 gr. bullets and the specs shown are miserable. No matter I have other powders that work in the 06.

My Browning A-Bolt 280 is partial to 58 grs of IMR 7828 and 154 gr SST's. It also shoot's the 150 NBT really well with this same load! I use the 140 class bullets in my 7-08 for the most part...

IMR 4831 and 160 partitions.

Ran some factory Remington corelokt 140’s over the chrono yesterday. They were the most consistent out of the others I tried which was Hornady 150 ELDX and Nosler 140 Ballistic tips. I have some 120 gr Barnes TTSX to work up just have to get time.
