- RIA / DERYA TM22 - SK semi auto rifle - 50 yards
I Have made small FREE modifications to this rifle and those mods have greatly improved the accuracy of this rifle. Besides the free floating barrel mods the rifle is stock as you would receive it from the dealer. Its a nice little plinker that has potential to be a real competitor amongst its peers like the Ruger 10/22 and its variants. I like to do things differently and try new things and this time its the Derya / Rock Island Armory TM22. I will be conducting ammunition tests with this rifle at 50, 100, 200 and possibly further. there 50 yard test will consist of 20 fouling shots to have the barrel seasoned for the ammo being tested. from there 4 5 shot groups will be fired to test the compatibility of rifle and ammunition.

I was "Snow Blind" through 1987 growing up in Florida.
It’s not the rifle, it’s the inconsistent rim thickness of the ammo. I rim sort most of my ammo for my 10/22 and it shoots very well with lower quality ammo and it shoots lights out with higher end match ammo. If you care to dive deeper into the world of rim thickness sorting and maybe weight sorting your ammo you will see most if not all the fliers disappear and tighter grouping from your testing and a more consistent group average for the ammo sorted. If the chamber end of the barrel is visible looking up through the mag well with the bolt closed you can measure the gap between the bolt face and face of the barrel to get that measurement then add to that the depth of the bolt face for your total headspace measurement. The best performing ammo will be close to if not the same measurement as your headspace measurement.
Interesting issues in this shooting video. Thanks for sharing.
I've had ZERO issues so far with Federal Auto Match ammo and with the OLD 711b standard velocity target ammo. I ran a few old Winchester copper plated bullets through it, but not enough to make any judgements (but zero malfunctions there either)
And my group of 10 rounds at 25 yards with the Auto Match were easily covered by a dime.
When I got my TM22 few weeks ago from Tenda, they recommended the CCI mini mag 22LR 40 gram! So I got 200 rounds of CCI. But I still don’t have time to the rang for the ammo test.😅
That doesn't seem to be a "ammo test" type rifle. I think if I had one and found one it liked I'd just stick with that. As always Ryan another great video. Waiting now for July and one with mo snow on the deck 😅
yes I agree
Hi Ryan, how does the semi auto rifle round differ from other sorts? Does it have a hotter charge or a different shaped nose or is it just marketing and there is no difference whatsoever?
Greetings from a very sunny Germany.
I am not sure to be totally honest but I would imagine that it would have a slightly hotter charge to cycle the semi automatic action. but that's a great question. thanks
What scope you using? Gun looks great!
It’s a Bushnell elite tactical 4.5-18 but now I switched to a discovery ED AR1-6 ffp which suits the rifle a bit better. I have a couple recent videos with it and one coming in the beginning of March. Cheers and have a great day
Hi great vid as usual see the snow is still there and may I pick your brains do you no of any mag speed loaders for the cz457 mags as I don’t have cast iron thumbs
I don't know if there are any and I have never used one to date. but that's the bonus of bolt actions you make every shot count unlike these things where its hard not to follow up faster
I never shoot lead bullets in my autoloaders. They foul up the barrel and cause feed problems like you experienced.
I didn’t know that
Stick with the copper jacketed ones.
Thanks Dan
Where did u get the 25rd magazine from ?
My local shop has them in stock
@@BROTUNED like online do you think advanced tactical is a good site
I have never been on it before but I’ll check it out. Look up accuracy plus Peterborough Ontario talk to them
From what I'm seeing on YT from you and others, the velocity of this ammo is right around transonic at the muzzle. Bad news if you're looking for any kind of consistency relative to MOA. I don't think sorting this stuff would make any difference.
I honestly don’t have the time to sort ammo so I just pay a bit more for the ammo and get pretty good results. I’m sure you could but I just can’t be bothered
Update: this is the best shooting ammo so far out of my stock CZ. Groups are averaging around .4" at 50 yds. Very surprising.
Which flash hidder is that?
Sure fire
*A bit rough but hey! Haha*
Maybe this is just not the ammo for it
_Hopefully the Derya 12ga Ive been gifted will pepper better 😁_
That’s awesome do you have it yet?
@@BROTUNED No but hopefully soon...
Very cool man let me know what you think about it when you get it
@@BROTUNED Yet all I can say is that the stock was cracked at the store out of the box so my stepfathergot it for very cheap instead of paying to destroy it!
He fixed it... and never fired it.
Ive never even shot a .22 yet so this should be interesting none of the less 😂
{It is a basic single shot but it will do the trick for birds and bunnys}
_One thing that id really hope to get is the pcp that ive been offered to review and keep._
I think the problem might be the magazine.
They are pretty fun
Don’t think it likes that flavor. 👍
nope!
TH-cam changed the magazine rule for inserting and removing, pretty dumb rule which is why they changed it back, but your mag has to be 29 rounds or less, another super dumb rule that no one follows, don't think they have people counting HAHA!
Thanks I wasn’t aware they reversed the stupid rule. Things are getting ridiculous here nowadays but it is what it is I guess lol but thanks for letting me know cheers!
AD waiting to happen……
😂
None of my guns like that S K shit ...
Really?
