Well, back from the range, again shooting the old marlin 81. First thing I figured out is that the range I was on last weekend it actually 100yard, somehow I got pretty confused about it, looks longer than the one I knew for sure to be 100 so maybe its an optical illusion between the one that is grass and one that is shale that looked longer. Still ended up with wind, anywhere from 0 to gusts of 30ish at least. Ended up playing with 7 types of ammo, and got some very interesting results. Never managed to keep them in a decent horizontal line.
I should have taken the cleaning kit with me as I did a few other targets after what's below and it was starting to spread. I was playing with the scope a fair bit between each ammo types though to get myself a decent chart of scope settings for each.
Interestingly, the lapua zero at 50yard remains zero at 100yard with the CCI stingers. With the lapua between 50-100 yards I cranked it up exactly 6moa, or 24 clicks? (still learning to used scopes, never had one until this one)
Sighted at 50yards with Lapua match, zeroed the turrets. Bit of an issue is the 10x40 doesn't have a good focus at 50yrd, I think its focused at 100, so I shot that distance seeing 2 horizontal lines much of the time, pita.
So at 50yards, doing 10shot groups, this is measuring the 2 furthest shots apart, in varying winds. I got:
Lapua match, .800".
CCI mini-mag, 1-3/8"
CCI Velocitor, 1-3/16"
CCI Stinger, 1-1/4"
Federal bulk ammo, 1.75" (I got 2 boxes of it mixed, one is new, one is 10yrs old, got 2 that shot an inch lower than the rest and messed up a half decent group)
Winchester 555 bulk, 1-1/8" one 1 went a little off, otherwise it was within 3/4" (I didn't expect that good from this ammo)
Winchester Target 22, worse one of the bunch, 2-1/8".
Then went back to the other 100yard range, groups varied from 5 to 10rounds and in between, and was surprised a bit about some results.
Lapua Match, 6shots in 7/8", one went up 1" above the others.
CCI Mini-mag, 4shots in 3/4", one off again by 1"or so.
CCI Velocitor, 7 shots in 1-1/8, one shot 1.5" off.
CCI Stinger, 7 of them spread out over 2.5".
T22, 555, federal all did around 2.5 to 3" being the worse one(fed)
Did manage 2 other groups at 100yard with the lapua that were right around 1", figured out that I'm throwing some of the random shots sideways(well... 4th time shooting in 9yrs...), and I gotta make a proper set up instead of a couple rocks and towels to rest it on.
Anyhow, sorry about having thought it was a 150yrd range and some of that confusion, definitely gonna be trying it out to 200yrd eventually though.
