 Is a .22 bullet that can spin freely in it's brass less reliable?

I was at the ammo store today asking if the centurion he had was copper as I've had much better luck with copper jackets in my 10/22. He goes on to tell me it could be the shittier ammo and proceeds to open a 333 box of winchester and grab a round and spin it in the brass. He explains that this causes pressure to be inconsistent and this could be my feed issue.


Thoughts?

What kind of 22 do you have?

Edit- nevermind...I see the 10/22 now.

That is not likely to cause feed issues, but it's not uncommon for .22s to work better (both function and accuracy) with some ammo than others.

I'd suggest posting this in either the Rimfire Forum here, or even on "rimfirecentral.com" if you want more complete information.

I've seen a lot of them spin. I don't remember them being any more inaccurate than others

Plated and jacketed are very different.

Not Jacketed, copper washed.

You can spin almost all .22 bullets within the case with little effort. It's very thin brass and soft swaged lead. Doesn't hurt a thing.

I knew I read something between the lines in his question. Guess I need some learnin.

jacket= thicker outer layer not necessarily bonded ?

plated= atoms or microns thick electroplate?

Plated and jacketed are very different.

The only jacketed LR was made for survival rifle use to prevent accusations of Hague Treaty violations (FMJ bullets in combat). Rimfire are heeled bullets, they are crimped before final bullet forming. The copper/brass colored ones are just a flash of plating and it is insignificant for expansion effects. Usually, such plated bullets are high velocity ammo.

As far as the bullet spinning , it is quite common.

With .22s, what works best in your firearm is what work best. Don't buy anything in bulk until you've tried a moderate sample (50-100 in the case of .22s)

Theory (aka gunshop mythology) can be ignored in this case. You know what works and what doesn't, while the counter person has far less info (aka hasn't much of a clue) regarding your specific firearm. Rimfire .22 is pretty much hit-n-miss by brand/label. FInd out what your gun likes, and get that. Ignore other recommendations unless they are recomendations to try a variety of different ammo.

Your ammo is likely copper-washed, not copper jacketed.

Very true, even lot numbers can make a huge difference. I have a Ruger MKII that will [benched and scoped] make a one hole group at 25 yards ONLY with one lot number of Winchester Wildcat. I bought every box the store had with that lot number. [bout 4 thousand rounds in 250 count boxes] It won't come close to that with any other ammo, it'll shoot 1 to 2 inch groups but nothing like this one lot number.

Moisture might get in the case easier if there is more play between the brass and the bullet.

Only if the ammo is soaking in water. Smokeless propellants and non-corrosive priming do not absorb humidity.

Rimfires are particularly sensitive to ammunition selection. I couldn't get a Smith revo to shoot with anything I had, but you could cover ten rounds of CCI Green Tag with a quarter at 20 yards, and thats good group shooting for me.

I use Federal bulk pack (525/box).

Some spin, some don't.

Can't tell any difference downrange.

I avoid the copper washed bulk pack stuff at all costs. My 10/22 chokes on it and it usually has crappy consistency in groupings.

My father said when he was young, my grandfather would get some surplus .22 that was jacketed. The other thing he remembered about it was it had this real thick case lube which would gum up his .22 rifle.

In '07 they were $7.87 at Chinamart. Have several 550 that I paid $7.87 for. I date & put the price on all .22 550 packs I buy. That's how I know how much they were back then.

you want to know how good your 10/22 can really shoot? get some wolf match.
