    To chop or not to chop

    Ive been thinking about chopping back the barrel on my Kimber 7mm WSM ever since I received my new replaced HRE can & after reading Tui's & lazys post I thought I'd see what you fullas think, my original gen 1 & 2 HRE cans butted right up to the for end but the new gen 3 model is over 3.5" shorter

    This is now being used as an alrounder 10-600yard rifle


    As it is at the moment, 22.5" barrel with 162 A-maxes doing 3000fps

    With new can fitted, a little long for in the scrub & quite front heavy

    What it would look like if I cut the barrel back to 19" plus 4" forward with the suppressor

    Not really, the difference between SAUM & WSM is only 2 or 3 grains, In the Kimber 72g of 2225 seems to shoot OK.
    If I chop it how much will I lose ? 120-160 fps maybe

    Chop it Phil, I don't think you would lose that much speed....... change to 2217 to see how it goes

    If it loses more speed than you would like, you will still have a more useable rifle.

    You can always rebarrel it, probably hasn't had enough rounds through it yet though, seeing as how you have never shot it hot...........much .....


    Opps nearly forgot, the pressure at the muzzle will go up with the shorter barrel...................better ask the suppressor how it feels about that......

    I reckon give it the snip - realistically, at worst you would lost about 150fps max maybe? Still more than enough ooomph for 0-600 yards.

    Dont run powder thats to slow, you will end up with unburnt powder sitting in the can and after x amount of shots you will end up with a bigger boom than you will like.
    If its guns, tits or tyres it's going to cost you lots of money

    Just got my rifle back from Mr Hardy. I asked too take off as much as possible without butting up against the stock - I didn't know the new suppressors were so short - but it looks and balance's very nice - A T3 270 with 4" gone - Hope it still works ;-) It's basically the same length as it was before it left with the suppressor on = perfect bush/paddock rifle capable out to 400-500 .. maybe.

    This is a weird trend.Buy a 7MM magnum and then turn it into a .280 thats still eats 70gr of powder.It will cost money to chop and recrown, wont help resale and will leave you with a rifle thats not particularly good at anything. Going by your sig you already have a .308 .

    But I suppose someone on the internet has done it so.......

    haha or that

    not much point chopping a magunm down to 19" get a 7mm08 an chop it down to that the speeds wont be bugger all difference an still do the job to 600m like you want, with cheeper brass, less powder, easyer on supperssors an quiter from the 7mm08

    but if you did chop it, id go to a faster powder not a slower powder for the suppressor an secondard burn in the suppressor from the unburnt powder..............my 18" 243 is harder on suppressors that a 26" 300rum with the same suppressor

    Just cut the fricken thing.
    You will only loose about 125.015f/sec +/- and you can always (should) ram some faster powder down it. And using the A-max up close it will prob work better a bit slower anyway, the A-max only needs a min 1400-1500 f/sec to open up so that few feet you loose is not really critical. Plus they still sell rifles, next time you might not make such a terible choice as a Kimber
    Just up date your life insurance policy first, and don't tell any of the forum sooks that you are loading it hot.....they all start crying and ring the police saying there is a man attempting suicide with a firearm......
