    Clyde doesn't live in Eastern Oregon where we hunters have to sometimes take longer shots at big game in the wide open areas of the region.

    Gents,

    Just thought you might find it intresting that Mr. Allen hangs his hat at the handloaders bench. Both he and his brother are active in the rifle area of our forum. Quig, you will love his guns. I haven't got one but there are a couple of posters on the HB that do and they say that the rifles are true works of art. Now this also begets that you will be handloading for this gun and as such you should put back a certain amount of powder, primers and bullets in you BOB.
    Hope that qualifies it so I don't hear the crys of it doesn't fit.

    Take care Be safe Poacher.

    How in the world do they get a .820 BC ?!?!

    The highest I've seen prior to that is about .6 or .7 bc for a 6.5mm bullet.
