    Reloading For short barrels

    Since joining the forum, I have begun to notice the shortie version of a normal hunting rifle.

    It occurs to me that this might be a fun thing to have, one day.

    Reading Ryan's account of his new 270, it occurred to me that I really know nothing about the specifics of reloading for short barrels.

    What kind of powder do you use as a general rule, and are there any other things to take into account?

    If I got a shortie, It would likely be 308/7mm08/243.

    In general you want to use something faster burning than what you would use in a long barrel but there are restrictions to this as you will find pressure earlier with a faster powder, there seem to be some exceptions to this rule such as reloader 17 which seems an excellent powder for most calibers in a short barrel, despite being designed as a powder for large capacity magnum cases

    As an example I know a few guys who run 308s and were using the likes of 2208 to run 130gr projectiles in a full length barrel but then went to the slightly faster 2206h with a short barrel and didn't lose a lot of performance

    You are trying to balance good burn efficiency and maximize velocity.

    As for loads it depends what you want. If you are a sub 300m point and shoot guy then going to a lighter projy (and usually faster powder) to maximise PBR is the way to go.
    If you like to turn turrets then you can still load long heavy-ish bullets and just turn a few more clicks

    I was assuming that I needed something to shoot effectively to 200m. anything beyond that is a bonus with a short barrel.

    Dont waste your time chasing every last fps, it doesnt matter in the real world, it wont make a difference, all it will do is cause head aches and frustrations. And dont listen to silly old cunts

    The best powder for velocity is the best powder for velocity.
    Maximum pressure is obtained in the first few inches of barrel.
    If you are getting more by going from say 2208 to 2206h you are loading to higher pressures and may as well just up the 2208

    Happy to be proved wrong by anyone who can back it up with hard data.

    Most velocity is achieved in the first 10 inches / 25 cm of barrel. Your barrel looks quite adequate.

    I run 2206h like Ryan and gibo, pushes a 150 grain SST at 2750fps from a 16inch barrel .308
    Will group well out to 500m subject to wind

    I find bm2 works well in my .375, 16 inch barrel sends them out at 2650fps for 250 ttsxm Just got a few 250 sierras to try
    good deer medicine, have decided to use the 375 for a bit as its handier being short compared to my other rifles
