It’s later production, serial number 2853.The USRA models evolved constantly over ther production run. I would be hesitant to use HV in one of the early guns.
Mine was one of the last few hundred made and the latch latching mechanism was very stout. While I felt perfectly safe firing HV ammo through it- and did on occasion- there was no real reason too as accuracy dropped off significantly wih the hot stuff. I mostly used CCI SV and got great results.

Where does TARGET velocity fit in relative to STANDARD and HIGH velocity?Target gun made to use TARGET AMMO! .... TARGET VELOCITY! ..... pass the Nacho's!
With the square barrel latch, from this article, we know your pistol dates from between 1934 and the end of production in 1941.The USRA models evolved constantly over ther production run. I would be hesitant to use HV in one of the early guns.

At 20 yds, one-handed slow fire, I was getting 3-4" groups with SV, but this opened up to 6-8" with HV.I'm interested to know what kind of accuracy they get with their preferred ammo vs what some of the HV stuff prints.
Thanks for letting me know your results. Pretty interesting.At 20 yds, one-handed slow fire, I was getting 3-4" groups with SV, but this opened up to 6-8" with HV.
I'm sure the gun was capable of better, but Im not the best one-handed pistol shooter by far.
I wouldn't push it. I have no trouble buying standard velocity .22s for my target pistols and elderly rifle. Target Sports has Aguila SV for 6 cents a pop. Unfortunately no CCI SV in stock today.I have several older revolvers for which high velocity .22 LR ammunition is not appropriate and I’d like to save the standard velocity rounds for them. Hence the question of can I use the high velocity ammunition in this pistol? It seems like the answer is yes, but accuracy will be compromised.
Understood.I wouldn't push it. I have no trouble buying standard velocity .22s for my target pistols and elderly rifle. Target Sports has Aguila SV for 6 cents a pop. Unfortunately no CCI SV in stock today.
Loosness in the latch lockup would probably be the only real symptom, maybe eventually difficult extraction. I seriously doubt the chamber would fail catastrophicly or anything like that.Understood.
This is the latest .22 LR pistol I own, all the rest are 1927 production or earlier. (This pistol was manufactured between 1934 and 1941). I do have a .22 rifle dating from 1979, and so perhaps I should save the high velocity ammunition for that.
Should I fire high velocity rounds in this pistol, which seems unlikely now, what would be signs of failure, impending or otherwise?
Between 1900-1941, H&Rs were built to a high standard. The USRA model was a passion project of their lead engineer and was every bit as well built as it's competitors like the S&W Straight Line and Colt Camp Perry- probably better.I would stick with standard velocity ammo for two reasons. #1 is that I have never had HV ammo equal the accuracy of SV. #2 is that it will put a little less stress on an old gun. H & R did not build top tier handguns.
