    Hello All. I have just had a Remington Model Seven rebarreled with a Douglas 24" 1X9 twist chambered in .243 WIN #3 contour. Just wondering if anyone has a similar build. Reason I am asking if anyone has a good load worked up for it. Just tring to here some other loads form other people. I haven't even broke it in yet that is coming this weekend. The gun looks great.

    While I do not own a rifle of those specs, I do have a load that shoots remarkably well in three 243's I have tried it in.......a Ruger Compact, a factory Remmy Model 7, and a T/C Encore. If conditions are ideal to shoot in I am talking 100 yard groups less than 1/4 MOA.

    It is 43 grains of IMR4831 (work up to) and 85 grain Sierra Gameking BTHP's. Give that combo a try and see how it does in yours.

    I have a 24" Douglas 8 twist... I got the 8 so I could shoot the 107 grain Matchkings... Hornady says the 9 twist will shoot their 105 AMAX's in most rifles... so with the 105's you might be able to use the Retumbo load I developed for my rifle...

    My rifle is a Remington 788, and the barrel is the 24" light target as I recall... it's not heavy heavy, but it's heavier than a sporter barrel... all else I did to this rifle was I bedded the action and floated the barrel... no receiver work was done at all.

    [​IMG] as the target says, 48.5 grains Retumbo with 105 AMAX's... use magnum primers, they do make an ES improvement.




    [​IMG]With the 107 SMK's, this is a 600 yard 3 shot group (don't wear your barrel out proving groups... if the first 3 land tight, try 3 more at another distance... it'll all prove out soon enough. The 25 shot aggregate mantra must be being propagated by barrel makers). :eek:

    The Douglas barrel is a good choice, and as good as anything out there if you ask me... better than most, actually. The glitterati sometimes put Douglas down, not "fi-fi the poodle" enough for them I guess. But they work, and work well... :)

    And with 4831, a slower but still accurate 105 AMAX recipe... see target for load info.

    I get 3000 (just over) fps with the Retumbo loads, and just under 2900 fps with the 4831 load.

    Good luck with the new build...

    I use 2.850 for the COAL... just at my rifle's mag length. Then I adjust in or out in .005" increments a couple stages both ways to find the best length.
