    I have a .243AI, 1 in 8 twist, 26" barrel, that I plan on shooting 95 - 107 gr. bullets. I would like to get your recommendation on which powder to start with so I dont use up the life of the barrel in finding a good powder. I understand that what works in one gun may not work in another, but at least I would have an idea where to start. I am guessing this config would take advantage of slower powders like H4831, H1000, MagPro, etc. but would like to hear your recommendations.

    TORCHRIDER, I'm using H4350 for both 95gr. VLDs and 105gr A-Max in a std. 243.

    I had a straight .243 win 8 twist and it loved 39.8 gr of reloader 17 cci br2 primer and nosler brass. I was getting a little over 2900 fps in a 26" barrel.

    Thanks for the feedback guys.

    I have seen a couple posts where 4350 seems to be working for folks. I thought that would be too fast for bullets in the 95-107 range, but I guess I was wrong. Please keep the reco's coming.

    Thanks rmk800. I have kinda become a Hodgdon guy over the years, but would not mind trying some Alliant powders. I have used R19 and R22 in other calibers in the past.

    Torchrider I did a ton of load testing for the 243AI over the last year. If you want more load info let know.

    RL22 will most likely be your speed king...followed by H1000. I generally burn up at least 1 243AI barrel a year and pretty run RL22 and H1000 exclusively.
