I'm trying to understand the differences in these two types of Norma TAC-22
Norma TAC-22
https://normashooting.com/shop/caliber/ ... 22-qty-50/
Muzzle velocity: 1,083 fps
Muzzle energy: 105 ft. lbs.
Lead round nose
Norma TAC-22 Subsonic
https://normashooting.com/shop/caliber/ ... ic-qty-50/
Muzzle velocity: 1,017 fps
Muzzle energy: – not listed
Lead hollow point
The second one is a bit slower, a bit quieter, but I'd think not by much. Is it less likely to cycle semi-autos? It says "Great choice for manual loading weapons with mounted silencers".
Re: Difference in two types of Norma TAC
2I would imagine slower equals less powder and not cycle a semi very well. I have bunches of sub sonic that dont work in my MKII I just got.

Re: Difference in two types of Norma TAC
3Both are 40 grain, so the difference in velocity should be due to either powder charge or aerodynamics. 66 feet per second isn't a big difference out of a long barrel. Weird, the paragraph below lists subsonic at 1033 fps - 50 fps slower instead. They don't list test barrel length.
Both should be subsonic out of pistols and probably most carbines. Should cycle just fine unless your gun requires high-velocity ammunition.
I think this is just different target markets - hunters vs. target shooters. My experience with TAC-22 has been that it is accurate but very dirty, with a very greasy lube. In my Mark IV, I need to alternate magazines with a plated bullet to clear out the barrel or it starts to have problems cycling. Sticky chamber, FTEs leading to FTLs. Shoots great as long as I alternate though. Your shooting experience may vary.

Re: Difference in two types of Norma TAC
4I concur with @wings about the issues with the Norma .22LRs being overly lubricated with a somewhat sticky lubricant. The casings stick in my 22/45 chamber.
The best solution is to take the time to put the cartridges on a paper towel, then use a second paper towel to wipe them down. I don’t know what the company was thinking with this waxy lube but it’s undesirable. I have 1,000 rounds of it, and it does shoot well other than the lube issue.
Keep in mind, regarding the subsonics, that although the load may be weaker, using most suppressors will increase the backpressure, so that may aid cycling on a Mk IV 22/45 or on a 10/22.
Just adding this For clarity: the lube issue hasn’t come up for me when using other Norma ammunition, which I’ve found to be a fantastic value.

Re: Difference in two types of Norma TAC
5Yeah, I have some Norma .22LR copper rounds I'm curious to try out in the 10/22. I shoot enough in cold weather that I prefer to avoid lubed lead.
