100M/YD 22LR 10 rnd groups

I dig it horesman2. I've got nothing to do at 50 yards this season, this 100y challenge will see me digging my CZ custom back out of the safe which I hardly shot last year :)
 
Each rifle will have ammo that it likes and does not like. Testing will soon expose those facts.

I test with one or two the expensive match ammos, to get a fee for what the rifle is capable of, and then test the $8 to $10 ammo to find a cheap ammo that is almost as good.

Each box of ammo will show a lot number. The ammo can be quite different, lot to lot, so if you find a cheap ammo that works very well, go buy as much of the same lot # you can find.
 
The size of the target might not make any difference. Using a larger target makes little difference other than to keep your shots inside the 7-ring.
Pick you own aiming point. The x may work until you shoot it out but the aiming point is your choice.
The target is essentially standardized. Your printer can be used to make something that better meets your needs by adjusting the percentage.
A new thread will be started when finalized. When the rules are published as #1, #2 will be and example of what a properly configured addition should look like and #3 will be the shooter's score page.
Time will tell and I appreciate the comments and suggestions.

Sincerely,

Mel

The 50yd thread is interesting and informative, but I’m trying to reach out to 300+ and I shoot 10rnd groups. I envision a less formal thread here. Please shoot at 100M/YDS 10 round groups. I have lots of pictures but have never been through the process of posting here. I expect my groups are pretty pedestrian anyway. Through dozens of 10rnd groups at 89M (that’s as far as my home range goes), with CCISV and a T1X, mine average about 1 3/4”. Some flirt with 1 1/4”, but I can’t depend on that. The Ruger Competition 10/22 has done a single 10rnd CCISV at 7/8”, but a 1 off really isn’t useful. The Tenex and Eley match from the T1X look pretty good, but a sample pack gets used sparingly. I always wonder what 10 rnds at 100 looks like for other folks. Let me know.

I was testing a new batch of ammo I picked up and here is what I got at 100 yards. It was breezy with some gusty winds so this is real world results. Hope this helps you and anyone else out.

When shooting groups i like to have a small dot as my aiming point then put 5 clicks or so of elevation in so im not hitting my aimining point.
 
I've seen diff shooters use anything from .21xx to this .225. What barrel has .225 grooved rifling ? The hole in the paper might be larger than the bullet due to tearing ? Granted a couple thous might not matter, unless it's 0.501 like for the 1/2" challenge.

The hole might be smaller depending on the paper and backer used . I measured a .22lr bullet hole at .198 on a target the other day.
 
The bullet diameter of these Eley/Remington Match measured 0.225" with my mitutoyo calipers. Even my lot of CCI SV in the old dark blue box measured 0.225" as well.

The size of the bullet isnt the whole story. Measure the hole it makes in the target. The paper can shrink back. The type of paper as well as the type of backer on the target stand can influence the size if the whole made.
 
This seems to come up frequently.

Bullet diameter is specified by and SAAMI and CIP. Both have the bullet at 0.225" in diameter (CIP's H2 = 5.72 = 0.225).

Bore diameter will vary between different rifles in general, but it's worth noting that bores made to SAAMI specs (for example mass produced North American rifles) will have slightly larger dimensions than bores made to CIP specs (for example, rifles made in Europe such as Anschutz, CZ)

SAAMI bores are .217" and grooves are .222" (5.51mm and 5.64mm, respectively).
CIP bores are .212" and grooves are .220" (5.38mm and 5.58mm, respectively).

The problem with deducting .225 from any paper target is that a .22LR round never makes a hole that size. Hole size will depend on the type of paper used. Usually a .22LR bullet makes a hole in a paper target that is .196 to .210".



 
Manitou your first targets on page 3 were rw50 and these latest one are midas+ is that correct.gotta see eagleye and one of them accurate 22lr,and grain and 22forever and rabid.those are the one I remember in the 1/2" challenge that itsybitsy groups.im probably forgetting 1 or 12 but hey.you guys set the standars im comein for ya all.but to be honest cand see me getting 3 shot groups like that Manitou. Was going out today to try but darn chores got in the way(which should never happen)

Yes, I understand the paper material subject. However my material is cardboard and informal. I just measure from the outside edge to outside edge of the lead marking. My test result is just is for my logs and not for score. When I compete in a shooting sport it will be PRS and what counts is "IMPACT" especially at 300 yards and beyond. :rockOn:
