who weight sorts their pellets and who measures the head sizes

For 50 yard target shooting (.177 field target practicing) I sort to the tenth for weight and hundredth for head size. A 4.49 vs a 4.51 makes a significant difference in my group at 50. I've found the wrong head size (anything smaller than .450 for me) results in the group opening up significantly. Those .446's shot into a 4.4" group, the .449s into a 1" group and the .450s shot into a .4 group. A set of JSB or AA 10.2's and 10.3 that all have a .451 head size will tear a rough hole with my gun.


 
I haven't cleaned my airwolf MCT and it still puts pellets on top of each other at 50 after several full tins.

Daystate told me go with Monsters at 5.5 or JSB heavies at 5.52. Those shoot very well in my MCT as do the AA pellets.

I have many other tins of other similar pellets which don't shoot well in different sizes / weights / manufactures. if you want 10 of each to try shooting in your Daystate let me know and you can have them. Just cover my shipping.

 
Sharoff, That is a very generous offer. I have tried monsters and several different lots of heavies but with same average results. Basically between .5 - 1.0 inch groups at 50 and not a small hole at 25 yrs.. I would get good results and then shoot again and they would not group well. Major head scratching. It made me think that cleaning my barrel was the deciding factor which some say they need to clean their barrel every 100-200 rounds. I will probably be trading in my Air Wolf for a Impact.
 
I am going for one rifle/platform for each caliber. My 177 is for field target and out to 50, the Wolf MCT Hi Lite for backyard pesting and squirrel out to 100, and I have a .25 / .30 Impact on order for reaching out further than that.

I couldn't see selling my MCT. It's just a great looking and performing high shot count platform that can effortless do pellet on pellet at 50 in the back yard range.. I'm looking forward to seeing the accuracy of the impact though but I just don't see it as a great looking gun. I'd have a FX Boss in a heartbeat if it had the adjustability of the Impact.

 
Yes, weighed and head size checked with 'pellet gage'. 

The scales I have weigh consistently, but I cannot be sure of its calibration (accuracy). So I choose one indicated weight (the numerically most common weight) and sort the rest into weight groups. I only check the head size of the single weight group - maybe because they are all one weight, it is rare to get deviation in head size.
 
Zephyr,

I'd sure like to know where you get your pellets. I did some shooting and sorting this weekend and don't get your results with mine.

Air Arms kept the .447's and left out any smaller. Weights from 10.2 to 10.5

JSB Exacts kept the .447s and left out any smaller. Weights from 10.2 to 10.5

Baracuda Match kept the .448 and .449 and left out any smaller. Weights were 10.6 and 10.7. So same weight with two head sizes (about equal distribution)

Crossman Premier (joke for a name). Weights from 7.8 to 8.1. Kept the 7.9 and 8.0 and left out larger/smaller. Then for those two weights, head size ran from .446 to .453. That's 8 head sizes for 2 weights. I kept the .449 to .452 and left out the rest.

Anything that doesn't go into a keeper category is used for practice ammo on my 20 yard indoor range where size / weight variance doesn't make as much a difference





 
I use JSB Heavies 4.52, there is nothing special about them. If you misunderstand my post I need to clarify - I use the pellet gage only on the pellets that are one weight (on my scales 10.32gr), of these I rarely see a deviation in head size.

The scales I use measure in 0.02gr intervals. Many pellets (probably 85-90%) of any tin do not weigh 10.32gr (the usual spread is about 0.6gr). When I did check the head size of all pellets I saw a variation. As any pellet that does not weigh 10.32gr is only used for plinking, I now consider it a waste of my time to check them with the pellet gage.
