Here are some pic of my targets with some of the pellets sized and some not at 25 yards. One clip at each target...9 shots.
This one is unsorted out of the box. not sized. This is just one of many that I shot. All ended up much like this target.

This one was not sized ...

Same with this one... unsized.

This was sized to .254 ...All groups that I shot with .254 were close to the same.

This was shot with .253 ... Most of the groups shot with pellets sized to .253 shot a tight groups.

This is just a start...there has to be a lot more testing to be done but to me sizing seemed to help......We are getting snow as i type...Blizzard warnings.....Sooo I wont be getting any outside shooting done for a few days....8 to 12 in..... ggeeezzzz ....Snow.. who needs it..... : ) Not me.... : ) I will find out how much it help when I can get outside and stretch out the yardage. If you have any comments just let me know.
