Pellet Gauges

[billydjann]

I have received my .177 and .22 pellet gauges today.
Measuring a small lot of .177- 4.50 Crosman Premiers I was shocked
to see the number that were not 4.50. Ranged from 4.46 thru 4.52..
I have a strong feeling why my groups change from time to time they way they do.

I would like to hear from others that have already used these gauges...
and what their findings are...

Once I check pellet size I plan on weighing and doing some serious shooting to find
out if all this will help.. Pellet head size and weight has to play a big factor in 30 - beyond shots.

I know your pain...lol. Gauging is a time consuming, yet informative process that pays big dividends in accuracy. I am gauging .22 pellets here and as you can see I have a lot still to go... ooof.


PS... A little blog about how gauging can weed out inaccuracies (for .177).....

This is the blog that got me wondering... so I bought .22 and .177 gauges.
Time consuming for sure. I am sure it will help...
I can't wait to see my results....

I'm not at all surprised. I notice large size differences in H&N, Beeman, and Crossman just by how tight or loose they fit my gun breech. I have noticed the smaller ones tend to fall outside the group.

Wouldn't it be easier to run them through a sizing die and then sort by weight? I just sorted 600 30cal pellets. Pain in the ___, but I can watch tv while I do it. Sorting did help with the 100yd groups. I would like to make a sizing die if I can find the time on day.

It might be easier...
I don't know much about sizing with a die ...especially for a .177 or even .22
..The main thing is that I don't know what head size my rifle shoots best... by gaging the pellets I will know soon enough... ( I hope )
I am hoping to find the perfect head size and shoot only that size head.
I am on a learning curve right now....but B. B Pelletier (Tom Gaylord) God Father of airguns - proved to me by his blog that this is a smart way to get more accurate...
I am convinced that head size is giving me a headache.
