    Over a year ago I started this project and promised
    to report back with the results.Due to long delivery
    of the barrel and the holidays I lost about 4 months,
    but have finished the rifle and started testing loads.

    With a water capacity in grains of 126.5 (24 grs more
    than the 416 REM and 8.4 less than the 416 WEATHERBY)
    loading is straight forward and shows promise.

    Dave Manson cut me a great chamber reamer and Hornady
    made a fine set of dies that sized 200 rounds of brass
    with no losses (may be a first for me).

    Below are some pictures .

    I will post load data,velocity,energy,and other info when
    testing is complete .

    I know that this is not considered a long range rifle but
    with over 6000ftlbs at the muzzle and a trajectory as flat
    as a 270 win it does have possibilities.

    Recoil is in the mid 50s and very manageable.

    Should be a real Stopper. /ubbthreads/images/graemlins/cool.gif /ubbthreads/images/graemlins/cool.gif

    Love the barrel finished. Did you do that or you farmed it out? Beautiful rifle.

    Thanks Desert Fox

    All work is done in my shop from start to finish.

    I love to make accurate rifles and like to make them
    look good as well.

    Again thanks, glad you like it.

    very sweet looking rig. is that a break on there or are you shooting this without one? i'm guessing this thing might have a bit of recoil.

    Why such a large contour barrel with gun that wasn't built for LR or why such a low power scope on a LR rig? It looks great though and the caliber is interesting.

    Nice looking package! I like the idea of the round too.

    Its based on a 375 RUM.The 300 had to much neck thinning
    and the 338 RUM did not have the case capacity needed.

    As far as recoil the 350 gr load produces 58.6 ftlbs of
    recoil. About the same as a 30/378 accumark (59.5 ftlbs
    of recoil. but 17.7 recoil velocity compared to 22.6
    recoil velocity of the 30/378 in a 7.5lb rifle. (the BUFF
    weighs 12lbs)

    But it is exciting with no muzzle brake. /ubbthreads/images/graemlins/laugh.gif

    Very very nice work on a nice creation!! (thou shalt not covet thy neighbors lathe /ubbthreads/images/graemlins/blush.gif /ubbthreads/images/graemlins/blush.gif or abilities /ubbthreads/images/graemlins/wink.gif)

    I noticed the bedding of the rear of the recoil lug. If I may ask, what's the thinking there, ?

    When I started this project the 375 RUM had just came
    out and Remingtion had no intensions of making the very
    popular 416 REM MAG obsolete by coming up with another
    416.

    But if they do "GREAT" factory brass and ammo would be
    nice.

    To answer Supermags question, The #8 taper and the laminated
    stock adds weight and with no muzzle brake (required by some
    professional hunters)this helps reduce recoil and recoil
    velocity.

    Also on the long range issue the "BUFF" has over 2000ftlbs
    of energy at 500 yards and unlike zumbo I feel long range
    is determined by the weapon and skill of the hunter.

    The scope was selected in place of iron sites and had to
    have lots of eye relief and field of view for dangerous
    game and be able to acquire the game FAST.This one will
    focus under 5 feet.

    Thanks for the interest.

    What a beautiful rig!!! I love the finish on the barrel and how everything (stock/barrel/action/scope) go together. YOu did a great job. Now I have some new ideas for my future .416 project.

    Roy Thanks

    This stock does not require any beding but sometimes
    I skim bed to improve the odds of having an accurate
    rifle in the beginning.On this one I decided to try
    it without beding.

    The boss you see is just to position the action so the
    beding screws are centered in the pillars and do not
    act as recoil lugs.

    The beding block/insert is full length from the sling
    swivel to the rear action screw and has recoil lugs
    bedded into the stock also it has a titanium rod
    bedded down in the pistol grip making the hole stock
    very strong and ridged.

    And on the subject of lathes I used to use a small
    home type lathe and every thing precision was very
    difficult so I bit the bullet and bought a heavy
    14 x 42 gap bed lathe and love it.Money well spent.
    Its like the difference between a custom rifle and
    a factory one "NOT EVEN CLOSE"

    That is a beast, nice gun. I bet that thing will knock you on your ass when you pull the trigger. Hopefully one shot is all that will be needed!
