    Recently picked up this. Rem M700 Mountain .280 1:9.25 twist, 22" light barrel. Unknown round count, the barrel was fairly fouled though.

    Then picked up a green Bell and Carlson Mountain rifle stock to put it in. One of my .257s on the bottom.

    I wanted to test run it with some factory ammo to see what I had as a starting point. 140gr Remington Corelokt PSP. Judging by the chrono numbers it could be more consistent. But hey, whaddaya expect for what it was. Seriously though, it's plenty accurate enough for a hunting rifle. When I begin load development I'll use some 140gr Accubonds.

    I shot one fouler into the berm before shooting onto the paper. First round was low left. Next three was a group at .32", not too shabby. Then I adjusted the scope and shot 10 rounds. The highest one I pulled- no big deal, still had a 1.47" group.

    I think this is prob the 5th or 6th rifle in a 7mm caliber I've had, guess cause they work pretty well. :thumb:

    Thanks Joe. I wasn't sure if I'd like it or not. I think it looks pretty good though.

    Yes sir the 280 is a great round. Nice looking stock you put on that rifle. I could never get into it as I'm a 270 FREAK.

    Rocketman, yep, right at 100. I generally shoot 120 to 130. I'm waiting on some drying to bring a load of dirt in for a backstop. It'll be a 160 ish plinking range when I'm through.

    Limbkiller, man, you know those 270s are weak..... just kidding. I've had one 270 and one 270 WSM, the WSM was pretty bad as.

    Very nice,.........I'm sure you could get the group to sub moa with good ammo!
    Corelokt is decent, but there are better choices.

    The w stock looks flippin outstanding!

    Thanks.

    Been doing some load development with Nosler 140 Accubonds. Takes a long time due to the thin pencil barrel heating up. I have one worked out at 51.5 gr of IMR 4350, avg 2618 FPS. I've shot 3 3 shot groups at 160 yds of 1.87" 1.56" and 1.31" for an average of 1.58".

    I've upped the charge weight a bit more to see if I get any improvement. If not, I'll go with this one ^^ as I feel the rifle can shoot a hair better than I have so far. 2 of the three rounds in each group are 1/2".....

    I like this rifle, I think it'll be the deer rifle for this season. :thumb:

    The 280 is a great cartridge. Killed my first elk with it. Handloading really brings out the best in this cartridge. Glad to see another 280 fan on here.

    Thanks JUNKIE.

    Took it for another spin with the upped charges yesterday eve. 53 gr performed pretty solid- 1.23" @ 160 yds. I'll load it again to check repeatability and chrono it.

    That's a grain over max in the Nosler book, but not in my old Hornady book. Stout load though, I can feel the difference over 51.5.... 'course it is a mountain rifle.

    5-22-12

    Finally got something I can work with. Tweaked the charge, then started tweaking the seating depth.
