I’ve been doing both lately and I believe that the practice does reduce the number of fliers when I’m shooting my .177 R9, however I can’t prove it decisively with my shooting skills.

For pellet head sizing I use a home made sizing die and ram that rounds and slightly flared the pellet skirt as it swages the head. I does take me about 5 seconds per pellet to size them but I do this chore while watching YouTube airgun and machining videos. After a couple low stress hours I have a 1250 count box of CPLs all uniformly sized to a 4.52ish mm.

A few weeks ago I started sorting my CPLs by weight into three groups, 7.90gr-7.98gr……….8.00gr-8.04gr………..8.06gr-8.12gr
The few pellets that are under 7.90gr and over 8.12gr are tossed out.
First I calibrate my scale………

Then the weighing is done same as the sizing, while watching YouTube airgun and machining videos. Here is the result after a few evenings………

Personally I believe that actual pellet head size isn’t very important as long as all pellets are large enough to be swaged a bit when loading into the leade (i.e. a snug fit). When all pellet heads are reduced simply by pushing into the leade they will be a consistent size determined by the leade itself. The issue comes when pellet heads vary enough that some pellets are “loose fitters” that don’t get swaged and other pellets are “snug fitters” that do get swaged. 

I’m coming to the conclusion however that extremes in pellet weight do affect the poi at longer distances and I am getting some positive feedback by shooting only one “weight sort group” at a time and that group is the one weighing 8.00gr-8.04gr which just happens to be the most prevalent size from my sort of CPLs that are advertised as 7.9gr.
