    Hi guys.
    Last night I picked up a set of RCBS .243 dies from a guy and he gave me some bullets. They are Barnes 6mm, 90 gr. X hollowpoints and Hornady 6mm 100 gr spire point. What data should I be referencing? When I check out some powder sites I can't find these exact bullets to get data for.
    Thanks

    They are on the high end of the 6mm used for deer and other big game.

    Varmint bullets start at 55 grams and go to 85 grams in 6mm.

    What are you wanting to hunt?

    I don't deer hunt anymore but may again someday. Mainly just looking for varmint loads.

    I alway like 4320 power and a 70 gram SP bullet starting 10 per cent below max and work from there.
    Reload 7 is also a good powder for the 243.

    My 243 likes 65 grain V-Max & IMR 4064.

    You bought deer bullets and they will kill anything but your trajectory will be more arched. Idealy you may want to consider a lighter, more fragile bullet for varmints which are offered by both companies. 55-65 grains is more ideal but the 90 to 100's will offer you the one load does it all combination.

    Measure your magazine and seat a couple of bullets so that the cartridge just clears. This will set your OAL length and seating depth. If you ever change this your accuracy will change. (lessons learned)

    Reduce a load below top book by at least 10% and build back up from there. You need to use the scientific method from this point to develop what works in your gun.

    Both powders mentioned 4320 and 4064 are great 243 powders. I use the
    4320 A LOT! Really like that powder. If your shooting varmints, I'd go to
    65-75 gr bullets. Good speed and accuracy. And you'll really like that gun. Limited recoil and fun to shoot.
