Thread: 260 remington, 6.5X55 & 6.5x47

    260 remington, 6.5X55 & 6.5x47

    Am I correct in thinking that 260 remington, 6.5X55 & 6.5x47 all use the same bullet heads i.e. .264/6.5

    You are correct.

    They are all 6.5mm's (or .264" s)


    BUT, they are not equal

    6.5x47 is limited to max 130 grain bullet

    260 Rem - 140 grainers

    6.5x55 - 160 grain max.


    260 Rem is a great all rounder for deer.

    Even if it were correct to call bullets, heads, which it is not, to call them bullet heads is a tautology.

    Not only is the .260 a good all rounder so is the 6.5x55, arguably better than the .260, even if only because of its popularity over such a long period of time.

    Blindness to suffering is an inherent consequence of natural selection. Nature is neither kind nor cruel but fiercely indifferent.

    Acrually despite using a 0.264" bullet the actual calibre is 0.256" Which is why we have the .256 Gibbs magnum and the .256 Rigby as they measured the bore size.. Due to the claims of European arms in 6.5mm being oversize I used the tool lathe at work and made up a stepped gauge. The start is 0.255" and it goes up in 0.001" steps to about 0.262". On checking the Mannlichers both have a bore size of 0.256" as does the Swedish Mauser. Using a digital caliper to measure as best I can the groove size both Mannlichers have groove diameter of 0.268". Oversize according to our American cousins but they work on 0.004" groove depth whilst the Europeans have groove depths up to 0.008" deep. Shallow grooves of course are cheaper to make. The Enfield rifling has grooves that taper and are 0.0075" deep at the breech and 0.0055" at the muzzle. I cannot recall the Swedish groove diameter so will have to have another look. Oh an one of the Mannlichers has a brand new Steyr made barrel fitted. It has fired less than 50 rounds including the proofing ones.

    I doubt it's possible to button rifle much deeper than 0.004" .

    I like them all although I cannot see the need for a .260 rem as after all I already have a 6.5x55, a 6.5x54MS and 6.5x63R (.256 Rigby) which i think covers it rather nicely.

    All that is old is good / tasteful / etc etc.....
