    Thanks [MENTION=199]Barefoot[/MENTION], just loading up some 87gr BTHP's, will go 43.5gr 2209.
    Going to see how these go, if not happy with the performance I'll switch to the 85gr Sierra

    I am literally doing the same thing! Couldn't find the Sierras when I was buying. Enjoy the Targex but just keen to try something else.

    Just put my hands on a "new" old R700 in 243, looking forward to try some of the recipes in between 43 and 44gr of 2209… So far i went up to just 42.8gr that gave me about 1" group… I also will seat a little longer for the next loads…
    Using Speer 85gr BTSP.

    Cheers.

    It depends on the rifle any two rifles exactly the same still may not like the same ammunition
    So we can not tell you what your rifle likes
    Only your rifle can

    Pick a projectile and powder from advice but the rest is up to you
    Do a ladder test or optimal charge waight test your rifle will soon tell you what it likes

    :D:D:D Good choice if you get both. The 243 is all you need out to 250m and the ""243 improved"" is good for twice that distance :thumbsup: but for the bush the 243 is a beast! SPs seems to work rather well for bush stalking distances.

    That's bullshit, they gotta be gd for at least 750m, that's what I read anyway

    I little report of "my case"!
    I decide i want to go with the 85gr Speer BTSP on my Remington 700 BDM with 1-9" twist (1-9.1/4" twist to be more exactly). As per photos i start low 42 and went to high 43grains with some random results.
    Component, Winchester brass, Federal 210 match primers, ADI2209 powder and projectile as above.

    First things first, my 100grains Winchester factory ammo shot 1" with easy at 100yd…

    Sorry i didn't take photos of the lower charges but they were not good anyway…

    Second go with the best charge from the start (43gr) and different seating depth. All seating depth measure from the ogive, i haven't work out the length to the "lens" yet…

    Very first shot with clean barrel is high(alone) the following 2 are together (43gr @2.270")… All the following shots was with a "dirt" barrel, all the strings had at least 20 minutes wait in between with barrel and suppressor on ambient temperature…

    I just preparing my brass for another round of "trying" to find the "thing"… By the way, the 43.5gr didn't work as do in many other rifles…

    Mate, looks like it will certainly kill things!!

    Might be worth giving the Sierra 85 a go too... I know Doubleshot waxes lyrical about them.....
