    I'm going to start working up some loads for my new benchmark barrel. It's a heavy 30", 1:9.5, 5r twist on a sako action. I'm looking for some suggestions.
    Starting point
    Rem brass
    Fed215m
    RL26 (working up from 85grs)
    225gr Eld-Match
    If RL26 doesn't perform moving to Retumbo or RL33. Also going to try Berger 230's. I'm hoping to achieve 3100 fps with this set up. Any thoughts?

    I shot the 225 out of my rum using Norma brass fed 215gm primers and retumbo. 26 inch tube. At 87 gr which is 2 grains less than Hornady manual shows max load I got pressure and velocity was only about 2850. I gave up on these and shoot the 210 Berger's at 3100 with no issues.

    I'd go to 95 gr rl33 or 102 gr rl50 myself with a 225 hdy in the 300 rum... rl25 and rl26 are a bit fast burning to get the heavy pill to 3K easily... Both of my 300rum rifles are doing very well with both powders using the 225 hdy hpbt, rem brass, and 215's....

    Thanks guys for the imput, I'm hoping to start testing next month. It's a brand new barrel so I got to go through there break in process. I'm hoping those eld-match shoot as well as they do in my other rifles

    I hope y'all don't mind me bumping this thread up.
    I've got a factory remington long range in 300 Rum that should be here tomorrow.
    I'm looking for as much as I can get.
    Would like to take advantage of the bc if the 225 eld match. I have nothing but nosler brass do far.
    Wanting to push it to a mile if I can (on steel).
    Thanks for any help.

    I've been using these bullets recently and having very good luck with H-1000. Running them in a factory Sendero and shot a 3" group at 500 yards a week before hunting camp. Have not been back to range since returning and have not run across chronograph at this time. Ballistics would indicate around 2960 fps.

    I got a 700 Long Range in 300 rum last year. It took about 100 rounds to get the barrel to speed up. I shoot the 225 eldm with a max charge of Retumbo in Norma brass; it shoots at 2970. I've held under an moa out to 1450 but haven't shot it any further.
