Home Forums Hunting & Shooting Rimfires 100 yd .22 lr group size?

I know the number of variables are vast, but what would you consider an acceptable 100 yd group size for an older bolt action .22 with nondescript ammo? Bought a Mauser MS420B last fall - late 30's vintage - scabbed together a scope mounting system that allowed the bolt handle to remain as manufactured. Used a base designed for a Winchester 94-22, then put tall see through rings on that. Mounted a Weaver 2-7 rimfire & finally found an hour to sight it in today. Ammo was literally a ziplock bag full of mix and match loose rounds. At 25 yds off the bench, 15 rounds made one jagged hole roughly 3/8" of an inch. As I was wrapping up I thought what the heck, lets try it at 100 yds. Shot 5 rounds, 4 were in less than an inch, the fifth was out two inches from the group, that could have been me or different ammo. Dropped about 6" from the 25 yard sight in. Back to my question, this seems to be much better than I would have expected at that distance, what experience have other rimfire shooters had at that distance?

It sounds like you lucked out if you paid a fair price.

Without further testing, and considering the mxed ammo, I’d call it a lucky accident. Enjoy the glow.

Sounds like an interesting rifle. We want pictures.

Was a good buy for once, I knew what the rifle was & the guy that had it needed money. The bore is mint, just wish my old eyes could shoot the iron sights respectably. Will try to get some photos tomorrow.

Those old Mausers are great rifles and I'm a big fan.

Not sure I'd count on that kind of 100 yard accuracy on a consistent basis tho.....

Those old mausers are very nice rifles

Photo of the target - had to save it, fluke or not!

Have a 10/22 that shot .4” group at 100 last time I tried it. Also shot 1/4” at 50.

Six inche drop is about right for SV. Perhaps the flyer was a HS round?

No way I could do that with irons now. Have a couple guns that will put 10 CCI SV in around 1" at 100 yds. Rest are between 1-2" for 5.

Olympic match grade rifles using match ammo are capable of shooting 10 shots into one ragged hole barley larger than 22 caliber at 100. I don't even want a sporter that can't shoot .5" at 50 yards. I don't shoot 22 at 100 anymore.

I'd hold onto that one.

I had a heavy kidd barrel on one that would put 10 shots of eley tenex in a 1in @100. I sold the barrel to get a kidd ultralight barrel, stupid move, doesn't shoot near as good.

I will, with tight hands.

Funny path to success. It is a Deluxe version, early '70s vintage, purchased for a song circa 1995. Shot ho-hum, so I went to work on it. Changed the trigger, full length bedded barrel and receiver and picked up a few different ammo brands. WW Power Points were the schizzle..... Weaver El Paso K2.5 with parallax adjusted to 50 yards.







It is also quite fond of SK Standard +

So Dan, how well does it group with the selector switch all the way forward?

Haven't tried that yet, give me a little time....

My two 37 Remington from my small bore prone days were 3/4 inch rifles at a 100 yards

My 10/22 is the CSC, but I think I need a retro one like that.

Mauser rifles can be exceptionally accurate rifles - I have a few MS350bs and an Mm410b all are amongst my most accurate .22 rifles that I have currently and would likely be capable of excellent accuracy at 100 yards - if I shot them that far (they are all iron sighted or low power scope (Mm410b)). Rifles I have shot at that distance - several Anschutz, Remington 37 and 40X, T/C Benchmark, Coopers, Kimbers and the likes are certainly capable of more than I am - wind, wind and wind along and ammo will be the primary limiting factors.

The current 10 shot NBRSA world record single group at 100 yards is .598" and the 5-10 shot group agg. record is .865",both in unlimited class....

I’ll run my mouth like there was no tomorrow when it comes to casual 50 yard shoots, and I can probably hold my own for a bit

But when things get pushed to 100 all hell breaks loose and the talkers get real quiet real quick and pics get scarce

My Annie's never miss at 50 yards. Never shot much at 100 yards. The sporter weight is more forgiving with various ammo. The heavy barrel is more picky. But I'm talking 10ths.
