.22 ammo question

Postby Marauder 1 » Thu Aug 25, 2016 11:12 pm

OK I notice that a lot of unburnt gets left in .22 semi auto firearms. So I was doing some checking on some of my ammo and I noticed that many of the rounds had bullets that would simply spin in the case while others were tight and did not.
Question is with them being loose will that cause insufficient pressure to get a complete burn? It also seems that could explain some of the velocity variations I'm seeing.
What started me down this trail was a video of a .22 ejection cycle and the cases were still burning powder on the way our of the pistol.
Watch on youtube.com

So I was wondering if re crimping the ammo might help with proper pressures, and with that said I have to find a factory .22 crimp tool since doing that operation on a press seems a bit dangerous.

I sure don't think it would hurt anything. I've noticed the same thing over the years. I don't think it makes itself known until you get into the semi's, where a hot round makes all the difference in cycling. I know I can sure tell when it comes to cleaning...some of the rounds today make a mess of the bore unburnt powder wise.

Exactly Barry, my oldest son has a Henry lever action .22 (LOVE that rifle BTW) and it does not suffer the same fouling as my younger sons Marlin 60. After a day at the range that poor Marlin rifle looks like it's spent the day at the beach inside. Maybe a dry lubricant would help with some of that but not all.

Mark, it certainly wouldn't hurt re-crimping your .22 ammo... but the biggest reason for the unburnt/dirty powder and (relatively) large SD's in velocity are because the operating pressures of the cartridge are so low. The same thing happens in shotshells, and to a certain extent pistol calibers as well. There won't be a huge improvement in the propellent burn with the powders we've got available right now, and you can't raise the pressures unless you go to a thicker case... like the .17 WSM which is based off a .27 caliber nail gun blank.
