Thread: .30 Cal T8 moderator or .270?

  1. #1

    Question .30 Cal T8 moderator or .270?

    Dear all, I am having a bit of a sort out with equipment, working out what moderator will go with which rifle etc. and I came across an anomoly.

    I have a T8 moderator which I have been using on my 6.5x55 and on the bushing thread end of the moderator there is some writing on it; BR T8 .30 1007

    Then on the side of the moderator are the proof marks and .270 WIN followed by the crossed swords device.

    Now being of an equiring mind, I can tell you that a 155gn A-Max .308 bullet will drop through the moderator. But is it a .30 cal mod or a .270?

    Regards, Simon

    when i had my .308/.270 about 5 years ago i got them both screw cut and fitted with t8s they were both .30 calls,i was told they made 3, one for .22.one up to 25 call..and one to 30 call..it looks like yours is a .30 call but been proofed for .270..i think the hole is 8.5mm.....i now have a .30 call t8 on my .243, its proofed..222/22.250
    • 7.5 mm hole takes 222, 223, 22-250, 6mm, 243, etc.
    • 8.5 mm hole takes 6.5mm 270, 7mm, 308 , 30-06 etc.
    • 10.5 mm hole takes 9.3mm, 338 etc.
    • 13 mm hole takes 45-70 etc.
    • The reinforced "magnum" model (stamped "M") for cartridges above 30-06 case capacity has 10.5 mm exit aperture as standard (other aperture sizes to special order).
    here you go!!

    I would imagine it's a .30cal mod that's been sent to proof on a .270? did you have it from new?

    I checked this with Jackson rifles a minute ago as I had to call about a stock, this is a .30 cal mod and can be used on a .308 without a problem.

    Moses, yes I had it from new. It came from Macleods with my Sako 75 Finnlight in 6.5x55. And thank you for checking for me, it is much appreciated.

    Steyr, Your post was most informative! The world of moderators and proofing is a veritable minefield, and common sense does not always seem to apply.

    It is as Moses has said, a 30cal Mod that has been proofed on a 270 rifle.

    My ASE Utra is a 30cal, but is stamped 260rem as that is the rifle it was proofed on.

    Irrelevant now as I use it on the 30/06. The 260 gets the Roedale which has no markings at all.

    Just because you are paranoid, doesn't mean they aren't out to get you......

    That's ok then, the T8 will come off the 6.5 and go on to the .308 (with a new rear bush). The 6.5 will then recieve the Roedale Happy days!!
