A little more precise

Following from my last post in this section of the forums "Not So Precision"

I managed to head out to the range again today...
Rifle: CZ452 ZKM Lux model.
Optic: Nikko Sterling Mountmaster 3-9x40AO (Mil dot reticle)
Range: 100yd
Ammo: 22LR Winchester Powerpoint 40gr Copper-coated hollow points
MV: Listed as 1280fps
Wind: Swirling and gusting at approx 20km/h (storm rolling in)

These were the results:

First target


This was essentially my sighting in target. I had not changed the scope from the first time, I had intended too but local bushfires prevented me from getting to range on Saturday which was a little charred today. Thankfully no damage to infrastructure there thanks to the hard work of our volunteer fire fighters... None the less you can see the spread as I tried to find the range. The impacts start from the bottom and work their way up the page, except the very top shot. This was my first shot and didn't see it hit the page but saw the dirt fly behind the target and came down some.

Second target:


The lines are an inch apart and the centre bull is 2cm

This one is much better, I'm actually quite pleased with these results.

The impacts start on the right and come left. The very left bullet hole was one I knew I'd buggered up.

There are 6 bullet holes in the centre (2 through the same hole in centre bull) plus the 7th out left.

In the end the scope my aim point was 4 Mil high and 1 Mil left, at least that's how I was using the dots in the scope to hit the centre.

I know it's not great but I was not using the sling as it was too tight and was making me bunch up (I've since loosened it off and is much better). I was also using a scrunched up towel as a rear rest and a dodgy stand at the front. Plus it's 22LR at 100yds!

The group on the centre line is 1.35" or 3.4cm (not including the one on the left which takes it to 1.6" or 4cm)

Nonetheless I'm quite happy, I'm in the process of making some sand bags, just need the sand! And once that's sorted I'll dial the scope in better. I'm going to try and zero it in for 50.

Thanks to all for your help and support, and another big thanks to Nathan for all you've done mate.

Now I've just gotta work on improving and getting that group really tight

Re: A little more precise
Forgot to add that the shots on the right in the second photo were aimed at the centre line of the target.

Re: A little more precise
That's a really good bunch of holes for 100yds. I see the big bores at 100yds that can't group that nice. And then they say something like, oh that's good for a moose at 200. NOT!

Nice shootin'.

Hi!

Nice shooting! The .22 sure is a fun caliber! Especially considering the cost of ammunition, it really is a joy to shoot and learn technique. Too much fun!

Cheers

Re: A little more precise
remember you can use kitty litter instead of sand .....and I think Ricardo had some suggestions on scent vs. caliber

Re: A little more precise
I have used sand, lead shot, kitty litter and used up crushed walnuts from my brass tumbler. They all work - but don't pack the stuff too tight as the forestock will prefer some softness/give. The frond bag packed really tight can result in vertical stringing for example. See the article on this in Accurateshooter.com

Cheers guys! That reminds me I have a sack of pearlite in the shed. It's a hydroponic medium and much much much lighter than sand. I'll use that instead.
