Title: CZ Rimfire Accuracy
Post by: 357MAGNOLE on March 02, 2018, 06:34:56 PM
What have you been able to squeeze out of your rimfire setup? I've never been a great shooter, but I have always been decent. I did a little work with my trigger, torqued action to 25 inch pounds and playing with ammo options and got sub MOA @ 100 yards this past week. First time I've ever done it with .22 LR. There was a slight breeze but still pulled it off. At 50 yards same setup gets me ragged holes if I do my part.

Excellent shooting, I haven't tried Eley yet but it is on my list.

I'm definitely impressed with and happy for your skill and success but, please, tell me this was NOT offhand with iron sights  :o

Lol of course not. I had a rest, a cheap one but It somewhat does the job and I use a Vortex 4-12

Gun seems to really like the Eley Sport, Wolf Super Match and the Lapua Rifle Match.

I’ve not used eley but my 455 American seems to like Federal Gold Metal Target.  It’s the best I’ve tried so far. (https://uploads.tapatalk-cdn.com/20180305/f0cd2c9b8626fac6a3d2bc4afc9c2376.jpg).  6 shots 25 yards one hole.  I shot 50 yards today an the group was just a little bigger but not a hole lot.  I will shoot 100 yards  next week , weather permitting

Nice! I look forward to those 100 yard groupings. Before I got the match grade ammo I struggled to make a 4" group with bulk ammo at 100 yards. The ammo makes a big difference.

nice holes 357......ammo (is definitely) a factor, the three your using are rated good....have you ever tried Aguila Super Maximum HV 30 gr another I read does well

I went out today for first time in a while. Had the chance to stretch it at 200 yards. Steady winds all day but for a gun thats not considered a premier target gun I think it did pretty dang well.  Cant really say I had a "flyer" but if you remove the worst one it was a 3 1/4" group. Add it in and just under 4"

Good shooting. I won't say it's typical, but certainly not uncommon for me to get better groups at 50 yds than at 35 or 40. I know it's partially the ammo. But nearly every one of my seven .22s have demonstrated this anomaly with one brand/weight/velocity ammo or another every now and then, and they always have. Conditions (temperature, humidity, and wind) may also play a part in it.

That is some laser shots with the .17 HMR. I have always wanted to try one out, but the cost and availability of .22 has so far prevented me from getting one.  I feel that if I was to pick up another longer range rimfire it will likely be in .22 mag.

Depending on your use, I would look very hard at the .17HMR.

I had a .22WMR concurrently with my .17HMR's....the .22 never got used.  With the .22WMR I struggled to get MOA; the .17's struggle to get over MOA; the trajectory to subsonic is flatter.  The .22WMR has more energy; so if you have pest eradicating, having a slightly bigger bullet that punches in a little deeper might do something for you.  For me, I've found the .17 HMR has plenty of energy, and capability; I've taken several badgers and several coyotes while gopher shooting.

I am fairly studious in my attention to ammo prices and availability; I shoot high volume gophers in the spring, so price per round and availability is a major concern for me.  The .17HMR was almost unaffected during the last couple scares; .22WMR got scarce.  I prefer the 17 gr Vmax load from Hornady; I generally pay .16 a round for it.  This means buying in bulk when things go on sale; usually it happens this time of year.  Murdochs (an agricultural chain store here in MT and surrounding states) currently has the Hornady 200 rd pack for $32.00 - 16 cents a round on the shelf.  The .22WMR in the 30 Gr Vmax (the preferred load for my rifle) was usually around 22 cents a round under similar circumstance.

The .17HMR has enough different bullet choices to compete and for the most part equal the
.22WMR but with superior accuracy.

Small Light skinned animals I’ll use the typical.17 plastic tipped and for bigger or thick skinned animals “like wood chucks or coyotes .17 hollow point 17gr or 20gr depending.

I have had the 17gr hollow almost exit opposite shoulder of a coyote.
My Marlin .22 mag has been in the safe since I got my Marlin 17v. and haven’t felt the need to buy more .17s yet.

All my cz455’s have been tax drivers with little tweaking out of the box.

My experience with newer CZ’s and 22 wmr has been lackluster at best. 

I have a Brno zkm 611 and hk300 that are capable of moa with most quality ammo and will hold 3/4” at 100 yards with their preferred ammo. But I too have struggled to get moa with the CZ-USA 22 mags. 

The variances in the bores just do not work well with the 22 wmr rounds I use.  With a chrono you can see differences.  The CZ’s will have higher average velocities, but much, much higher deviation/spread.  I ran patches with polishing compound down the bore of one of my 455’s, and that helped some, but still not grouping as tight  as my Hk or Brno. 

When I need more distance & punch for rimfire, I reach for the Hk with VMax or tnt green.

Nice shooting. Is this .22LR?

22 lr as are all the Ultra Lux 452 rifles.
Here it is mounted in a Boyds stock.

Nice shooting!  I'm going to have to get my 455 Trainer out of the safe and start enjoying it and trying some different ammo types.
