My 03a4 replica

i was thinking that also, when base put on, it was recommended to put a shim under front. been thinking that for 600 that might be a issue

Shim the front. You will do just fine.

[pelago]

what i know for sure now

there are two shims under front base between base and receiver, combined thickness is .020, each one is .010..........

about 85 total clicks from zero up, might be a couple more, but not going to force the issue to find out

with shims in place i need 21 clicks to hit at 100 yards

but what is the adj, 1/4 moa or 1 moa, called parsons scope repair and (lyman recommended) and he was just not sure....

took shims out and will reshoot on monday

my normal come up for 308 and 223 is
4 1/2 moa for 200
9 moa for 300
20 moa for 600

use this for three rifles and they put it in black for silghters

Is that an Alaskan you have mounted? If so the clicks are supposed to be 1" @ 100 yards. A4's bases seem to have been routinely shimmed during manufature and targeting. Then again virtually all of them were equipped with M73B1's (or one of the variants). The goal was to have the A4 w/m73B1 usable up to 1000 yards with the internal adjustments.

it is a 40's vintage alaskan, and i called lyman and was directed to parsons scope repair and i talked to them and they are just not sure if it is in fact 1 moa or 1/4 moa

if it is 1 moa then 85 minutes available would not be too far off for 1000 yards, but not with .020 shim in front. i doubt if i will ever shoot it at 1000 yards, i do have a place to shoot 1000 yards, but do i want to shoot a A4 at 1000, but probably will shoot it at 600 at the cmp games

The Lyman Alaskan is a 1 moa adjustment scope, when I adjusted it from 300 to 600 at Butner in the spring I went up 12 clicks (Minutes) and was in the black.

[pelago]

what was your 300 setting??

ya know i wondered about that, not sure if 1944 shooting with hunting type scopes worried about 1`/4 moa adjustments..

l am not sure what .020 shim thickness did to overall group, but they are now removed and we shall see

have a 48" high target backing, going to put a 1 MOA cross about 2/3 up from bottem, then a magic marker line from top to bottom, then go to mech zero at 25 yards and let fly, then work it back to 100 yards

be interesting

[Match223]

I went to Butner all I had was a 100 yd zero, I went up 6 (6 min) clicks to start my sighters @ 300, added some elevation and wind after the first shot but was in the ten / X before the 6 sighters were finished. Then it was 12 up (12 min) from 300 to 600 with adjustments to get it to the 10 ring. It will definately get you close.

cool!!

i shot a russian nagant and it was not mine, i shot with a young man named robert. i had mine, but it had serious trigger issues (took two men and a boy to pull trigger, probably ten lb) was quite surprised at how i did, 142/10 for the 600, took some getting used to it cold at the three hundred

okay, now for the ammo, what were you using, i am using lake city case, winch primer, 168gr hpbt smk
48 gr 3064

i wonder how they will modify the 'match', i did not like the 'group' sighters, and that did not really allow for two shooters?? liked the team aspect of it though, but i enjoyed myself

[Match223]

My team member and I had enough of the Hornady Garand ammo left over from Perry last year to get us thru the match, the original Rem barrel liked it. I liked the format, I had shot ot at 100 yards to get the zero so my teammate shot the sighters (there is no way both shooters can shoot sighters at either stage) and I gave him corrections with the spotting scope.
I was on the little end, I was shooting next to a USMC Sniper 1903 and a 1903A4, the guys we scored for shot a Mosin on our point.
The only part that I didn't like was the 600 yard walk.
I don't have a clue what they might change, as long as they keep it fun I'm in.
