Not bad for a rimfire aye!

Nice mate, what scope are you running on this?
Excellent at that range, I am yet to validate on paper at over 100 but have already tipped over a rabbit with one shot at 179m using a slight holdover (guess).

Yea it's a great wee calibre, I think there would be quite a few factory rifles out there that would be able to do this but as you can see on the target it is effected by wind a lot more than heavier rounds. Only downside to mine is it doesn't like the VMAX as much as it likes the TNT's.

It's just got a vortex diamondback 4-12 bdc on it so nothing flash however it does seem to dial alright although I've never dialed up more than 5.5 MOA with it.

I suck

Yeah but at least your shooting isn't to bad

Good day aye Gibo Ha Ha

Prick of a day, i really do need to stay away from any sort of attempted accuracy shooting with a hang over, idiot

What shall i call this kind of shooting? does "break the line" count as a hit or miss???



NOTE!!! The first shot at the 1/2 MOA icon i was aiming at the 3/4 MOA, so nothing more fair than keep shooting the 1/2…

Had a go at this with my .223 today. Called every shot as good but my cross hair covered the the 1/2 MOA marks even on 15x
My bad eyes probably don't help.

I shot it on 10x. Would have been a nice group and would appear my zero was out a fraction but I checked velocity on a 6 rnd group a bit before and all 6 went bang on but around the same height off center.
Dumb game this one

@R93, it is a "dumb" game but it is fun! It is how we "catch ourselves" doing thing for a "good cause"… I am 100% sure i had 2 big flukes on my shooting… Sometimes "just" a bit of "canting" can change "that" much the POI…
Keep the good work!

I was pretty keen to give the dumb game a go today until a certain ^^^ smart ass made me look silly , its so much easier shooting deer you no the shot could be a few inches off but hey dead deer , on paper it looks so much worse as if that wasn't bad enough the said smart ass had to start shooting things 728M away

Good thinking. Most likely a canting issue. I was playing around with some .38 sp loads in my. 357 while the barrel cooled on the .223 after the first group I fired while velocity testing.

I think I remember lining up with the straight lines on the target which were not level without a second thought. Rookie error.
I was also shooting off a bench which I rarely do so I was thinking I may have changed my position slightly after the first shot.

Good, you'll need them

Offset aside, very nice grouping if you put the shots all together.

Unlikely to to be canting though isn't it at 100yds when the bullet fall is only 70-80mm. 10-15mm to the left would require the rifle to be rotated by 10 degrees. There must be some other reason for a change in zero, and as you say shooting position is always enough when you're operating down at sub-MOA.
