    they are 5 shot groups at 100 yards, notice tehre are 6 holes next to the 12 thou target, one of them belongs to the 10 thou group but i aimed at the wrong target - oops.

    now its time to work on the velocity and up the powder

    Known as you are for upping the velocity Gary, what velocity are you pushing them out of there now? What FPS do want to achive?

    PS- Good shooting for the 16 thou
    Position and hold must be firm enough to support the firearm
    The firearm must point naturally at the target without any undue physical effort
    Sight alignment (aiming) must be correct
    The shot must be released and followed through without disturbing the position

    As discussed by the miracle of telephone earlier earlier today - your results are an object lesson for the armchair, never-tried-it, but know-it-all- 'reloaders' on here who claim that whacking in n grains of do-dah always does the biz. Fair play to you for worrying about the nth degree of accuracy, and the nth degree of humanity. You are the better man for it, in my view.

    didnt chrony them, 41 gns was giving 3850 fps. will chrony them next time i'm in the mood, and work up the powder until i feel its right and doesnt loose accuracy. i guess the acid test will be with the next batch to see if it really is the sweet spot or just luck that i put 5 in the same hole. looking forward to trying a 200 yard target.

    Kevin, as always your posts make my brain hurt and remind me that i should have read more when i was younger! yes the accuracy is what i was chasing, and touch wood - it looks like i've found it, but with regard to humanity, i am very much lookling forward to treating some of the wildlife in the local area to a lesson in humanity - tooley style. i still dont get why they make the cases so bloody big if youre not allowed to fill em to the top.

    Never mind the rifle porn. This confirms that you are a very bad man.

    great group you have there. i wouldnt be to worried about the speed if your up in the high end of the powder charge anyway. that will be more then fast enough.
    i ues to run my 222/250 pretty fast. but now have backed off abit. as the groups are better.

    i would much perfer the rifle to be accurate then flat out speed
