"p.s. what is that little set screw, on the rear sight, for anyway?"

I believe it's to keep the rear sight from moving in the dovetail. That's what they do on my MK III and MK IV. :thumbup:
tightened it up this morning as it was backing out of the hole. thx for the reply.

I fired another group with the shim in place. group size is actually bigger.
Have you tried different ammo?

If you have some CCI Blazer 40 gr LRN, try it as it produced smaller groups than Federal Auto Match 40 gr LRN for me (25 yard 10 shot group with 10/22 Take Down) - https://www.thehighroad.org/index.p...-thickness-for-accuracy.850634/#post-11113638

index.php


And at 25/50 yards, Federal 38 gr CPHP Field Pack and Aguila 40 gr CPRN produced smaller 10 shot groups than Federal Auto Match with 10/22 Collector #3) - https://www.thehighroad.org/index.p...lector-3-break-in.859106/page-2#post-11310458

And while Armscor 36 gr CPHP did not produce smallest groups in my 10/22 (I am up to over 20 different 22LR ammo comparison), it did produce 2" groups with my GSG 1911 - https://www.thehighroad.org/index.p...22-collector-3-break-in.859106/#post-11307816

I think all of california is moving to phoenix and prescott/prescott valley. insight is all tactical. the old guy that had it before stocked a lot of great used firearms. I liked the old store much better.

Me too. I used to use their range ten years or so ago, and bought a few pieces there. That's where I took my CCW class-- I had no idea the instructor would wind up owning the place one day. It was a cool store before it got all modern. Bob the range guy was really interesting to talk to; he'd been an international photojournalist back when there used to be such a thing.

no, I won't try different ammo until I get this barrel shim thing sorted out. i'm sticking with the federal automatch. i'll get back to your post after this when I get serious about matching gun to ammo.

murf
 
I decided to replace the current shim with a thinner one. 1230192216.jpg 1230192216b.jpg i'm thinking the wider shim may be pressing on the sides of the frame and not the bottom. i'll find out tomorrow with another test.

murf
 
another ten shot test today: IMG_20200101_0001.jpg . looks like the group opened up on the second ten. the barrel is a bit loose on the frame again. not as bad as before, but I can still move it side-to-side. i'm going to try and smooth out the frame cut and add a shim.

I like tinkering,

murf
 
so I decided to shoot my mkI using the same ammo, at the same distance, with the same rested grip: IMG_20200103_0001.jpg .

that is what I get for assuming the problem is with the gun. and the barrel still wiggles a bit. maybe a floated barrel is a good thing.

time to see what ammo the mk II likes.

thx all,

murf
 
Nice. :thumbup:

Can I suggest CCI SV 40 gr LRN, CCI Blazer 40 gr LRN, Aguila 40 gr LRN/CPRN as they have produced smallest groups for me consistently.
thx for that. a good excuse to visit the gun shops!

I have found CCI Standard Velocity, Mini Mags, and Wolf Match Target to give consistently great groups in not just my Ruger Mk.II but in every other .22 I have.
 
I think I have the cci standard velocity. i'll look out for the wolf match target.

murf
 
Wont be cheap but I bet the Volquartsen guys could fix it up nicely
i'm going to take it out again and really try to bear down when shooting. from what swoter is saying, I may just shim it and leave it alone.
I don't think I will be spending much money on this one. i'm picky about accuracy, but this one isn't really that bad when compared to my mkI.

update: IMG_20200105_0001.jpg IMG_20200105_0002.jpg

I shoot better seated leaning against my truck tire. the mk I has a fantastic trigger compared to the mk II. I felt better today and the sights and target are a lot more clear than before. the mk II is not even close in the accuracy department here. golden bullets are not accurate in either gun.

i'm going to fix the problem with the mk II, hopefully, by glass-bedding the frame/barrel junction. i'll report back in a different thread.

thanks for all the help,

murf
 
In reference to the loose MKII I have a government model that became loose from disassembling it for cleaning. The lug itself became worn and Rugers fix is to squeeze the channel where the barrel sits. There is another way take a piece of stainless steel feeler blade of the appropriate thickness between the barrel lug and the frame. You will have to cut the feeler gauge to fit it in the lug take your time. I did this to mine over 30 years ago and it is still tight. Then never take it apart, just take the grips off of it and use whatever cleaning method you prefer I use brake clean and canned air to clean the trigger mechanism. Hopefully this helps someone rather than having shims sticking out between the frame and barrel. By the way Prescott Valley Guns gets a fair amount of my money.

Your shim ides is correct and the above poster hit it on the head. I have a Volquartsen frame and Ruger upper on a 22/45 and VQ supplied a couple of shims to take up any sloppiness in barrel fit. They looked like they could easily be cut from a Beer Can. My shims all fit inside the frame and do not protrude our of the frame. You may give Volquartsen a call and see if they have a suggestion other than one of their very nice but very expensive frames.

Otherwise, you may figure out a way to "bed" the barrel using JB Weld. If possible, set it up so the barrel will separate from the frame for cleaning.

I can tell you that stainless steel shim stock will not crush over time where I am not sure about beer cans, maybe use a stout beer can. LOL

so I decided to keep the fix here.

jan 7 - acraglassed the frame at the front and back frame/barrel joints: 0108202130.jpg 0108202130a.jpg . these two pics are the final result of three layers of acraglass; the first layer was applied to the frame and the barrel loosely fitted to the frame. the glass oozed out and almost locked up the joint but I broke it loose while the glass was relatively soft (whew!!). the layer was not thick enough to tighten the joint, so I applied a second layer to the front and back of the frame. this time, the layer was thick enough to tighten up the slide, but someone couldn't figure out how to put the gun back together and blamed the too-thick layer for the assembly problem and sanded down the layer again. well, dummy assembler finally figured out how to assemble the gun so a third layer was applied to the back of the frame. this time the layer came out thick enough and the assembled mk I gun has a nice tight lockup.

tools for the project: 0108202131.jpg 0108202131a.jpg . the fix is not that difficult, just time consuming due to the cure time on the acraglass. I made a sanding block out of a ratchet socket the same diameter as the receiver. the key is to get the back barrel/frame joint the correct height to allow the hammer strut and spring to work properly. the higher the joint, the closer the strut spring to the strut and, therefore, the more spring tension on the trigger sear. the trigger pull went up from 2lb. 8oz. to 4lb. 2oz. with this fix.

while looking over the gun, I noticed a few things: the lockwork was dry and dirty which bound up everything so I lubed and cleaned the internals. the back of the receiver had gouges inside the bolt channel 0108202303a.jpg so i used my trigger stones to smooth the gouges out as best as I could.

I finished the work up last night and reassembled the gun this morning. i'll be taking it out for a test run this afternoon.

shot a few rounds through the mk II: the barrel is still tight, the group is round and (for me) small, and I had no malfunctions of guns or ammo. the next step is to find ammo for this gun.

pics of this afternoon shooting: IMG_20200109_0001.jpg IMG_20200109_0002.jpg IMG_20200109_0003.jpg . the group size is not much smaller than the one shot with the loose barrel, but I don't trust a loose barrel. anyway, the test is over and the mk II is going to be my new 22lr accuracy gun.

more pics of my shooting range and how far 30 yards is: 0109201441a.jpg 0109201444a.jpg 0109201450.jpg

next step: IMG_20200120_0001.jpg IMG_20200120_0002.jpg IMG_20200120_0003.jpg

cci target ammo looks good and is my choice for best group. note: i'm shooting all these sitting against my truck tire resting the gun on my knees and two handed (except for the 380 auto target).

the cci stinger group is good, but I had a ftf which lead me to find out the magazine I was using was bad (the bullets and the case were being dented on loading).

the minimag group is also very good. i'm not having much luck in picking a "best" round for this gun.

IMG_20200120_0004.jpg IMG_20200120_0005.jpg IMG_20200120_0006.jpg

here's another group of the cci target ammo. this group is even better.

the win power point group is all over the place and is rejected.

the win superspeed group is alright and very round, but not as tight as the cci groups, so, it's a reject.

so, this gun gets the cci target, cci stinger and cci minimag rounds. the target is the cheapest, so I probably will run a lot of that.

I also need to test the federal automag again, as I have remedied the loose sights and bad mag.

and one last pic of another test i did today of rmr 95 grain fmj bullets out of my ruger lcp II: IMG_20200120_0007.jpg most of the bullets went high so the target will be lower next time.

the rmr load is not accurate enough, yet. my carry load is still the 100 grain lrn load. i'm still tweaking the fmj load, so who knows.

murf

p.s. I forgot to mention that I only had two cups of coffee this morning, in stead of my normal 12-cup pot of coffee. that may have something to do with the slight shrinking of the groups today.

I know I'm finally grown up, I left the gun shop two weeks ago and didn't even buy ammo (which I usually do to support them).
 
another test of the rmr 95 grain fmj bullets out of my ruger lcp II, this time at 3.5 grains of w231: 0131201510b.jpg this is shot left hand only and standing (no support) at 30 yards.

the elevation is ok, but the right/left is no good. i'll have to tweak my grip a bit. the load is a bit hot as i'm getting firing pin drag on the primers. i'll back the powder charge off a tenth of a grain and try again. this load has a lot of promise.

i'm also shooting the mk II, but at golfballs and fruit, no targets to post. the cci target ammo is the most accurate so far and I doubt I will try the expensive stuff as I'm not competing in bullseye competition.

thanks for watching,

murf
