    Can some one explain why the Wby manual that comes with the rifle dose not
    explain how to break in a new barrel??? As i see most aftermarket barrel suppliers do explain how to do the breaking.

    They may be taking the neutral route to break in. (Its up to you).

    I would do a shoot one and clean then repeat until you feel that it is ok(normally8 to 12 times)
    then shoot 3 and clean and after 3 to 5 times then shoot as much as you want but dont let the
    barrel get hot.

    This will aid the barrel in less fouling, and normally it will speed up the load develoupment.

    You are welcome!!!

    I used Sweets for many years and found it very useful under certain circumstances.

    It is very good for cleaning a severely fouled barrel without wearing out several brushes
    but I never leave it in the barrel more than a half hour before removing it.

    When I use Sweets I always follow it with a mild solvent to remove all of it and after the
    barrel is clean apply some Hoppe's # 9 or a light coat of gun oil if it is going to be laid up
    for a long time.

    For normal cleaning I like the Butches Bore shine because it is much more mild, even so
    I follow it with the hoppe's or oil for storage. Lilja recommends the Butches for his barrels
    and if it is good enough for him it is certainly good enough for me.

    Before I fire the rifle I always dry patch several times.

    Sweets will work to remove copper in your barrel, but just don't leave it in there for much more than ten minutes. I have three bottles of 28% amonia, and I never leave it in the barrel longer than three or four minutes. Still if the stainless steel is fairly good you should be able to get by with as long as 15 minutes (I don't really recommend it). I like Shooter's Choice and Butch's Bore Shine for normal cleaning, and I still don't leave it in the barrel for a long time (I have plugged a barrel more than once to let it soak over night with no problems)

    My Accumark liked 200 gr partitions,Fed 215 primers and 114grs of H 50BMG to 117 grains.

    My new 30/378 (with a 30'' Lilja SS barrel) likes 118to 126 grains (A Max Load).

    The best accuracy is with 118 grains @ 3312 ft/sec the Max load tested was 126grains @
    3492 ft/sec and was still under 1/2 MOA but my rifle is set up for heavy loads and has lots
    of freebore, so dont try it without working up slowley and watching for pressure signs.

    The one thing I have noticed with the heavest loads is a huge fireball (I dont think the rifle is
    using all of the powder) and with no increase in pressure signs I have backed off to 117 grains
    and been very happy with SDs and Velocity.
