Re: OVERALL LENGTH .22 AMMUNITION---BORED.
We ran into an issue with the MG2 and had the factory make a change for ammo length. CCI lots were getting longer on newer ammunition. The bullet tips were catching on the bottom of the barrel as the carrier lifted the cartridge during feeding.

Greetings,
Interesting....
The CIP (European equivalent of SAAMI) shows the max overall length of a 22lr to be 25.40mm (1.000 inch).
Perhaps you could post the actual Excel file as several cartridge measurements got truncated.
Cheers,
Dave

Dave, I'm not seeing the truncation you mention. can you be more specific. They are to the closest .001 of an inch currently.fc60 wrote:Greetings,

Greetings Jim,
The *.xls file helped.
It shows the additional two brands measured.
I have heard of CCI causing issues with the Pardini. However, many local shooters use CCI with no issues.
CCI did have a problem with the wax lube dip. In days with varying humidity, the wax would build up on the tips after the lube process.
Based on your caliper exercise, I would suspect all brands measured would function in the magazine.
Thanks for your efforts in Metrology!

I don't remember where I got this one from, but it's on my hdd:
and on a somewhat related note, I was bored one day too and measured various dimensions on different brands of 22LR that I had around. I have no mad excell skillzzz though, so it's a line drawing:

This is why I use Norma Tac22 in my Pardini. less chance of the 2nd round getting stuck in the mag. I also use Eley EPS which has a fatter nose and it shorter.
