Head size rule of thumb.

What I have found out is this . I sort by weight and head size I have found that I pretty much get the same results from pellets in the batches I make up. I just have to remember to make slight adjustments when I switch to another batch. On occasion I find the smaller ones to be more erratic where they are fine for plinking but not for Bench Rest. I’m not a competitive shooter mainly because there is no one around where I live that is into air rifles as I am. But I do get get good results.

I just ordered a pellet gage. Up to now, I've only washed, lubed and sorted pellets for weight. I've noticed in my shooting ( a springer ), as I hand load each pellet, some slip into the bore quite easy while others there's a definite resistance as I insert it fully. Now that's gotta be head and skirt size related.

Opinions are, head size DOES make a difference in accuracy, at least, consistent accuracy. When I get my gage, I'll go thru the different weight pellets I have sorted already and play with different head sizes for each weight to see what my gun shoots best. Only then will I try to order new tins of pellets at a specific head size. But if you watch the videos, even a tin labeled a specific head size will have variations that you'd need to go thru to weed out those that don't conform, if, you want to remain consistent with why you started checking head size in the first place.

This procedure, from what I read, seems to be the "rule of thumb". Trail and error.

Geez, I guess this means I'll be rolling pellets pretty soon too. You guys are making me anal in my old age.

I saw this neat tool on YT for "resizing" too large pellets, multiples at a time.

Not that I'm a skeptic, but, I'd have liked to see him verify the uniformity of the head diameter of the re-sized pellets with a micrometer. The video demonstrates how to properly use the die, but it shows nothing of its performance.

On second thought, it would be interesting to see this demonstrator actually mic the heads before he resized them, and then again after.

Rather than micing them, which is difficult at best to get accurate info, using a pelletgage before and after would have been the ticket. I'll add that comment in the video.

Once you size and weigh, be sure to sight your rifle in on That Pellet selection. There is probably a specific size and weight your gun shoots best. However, as long as you shoot a specific tin [sorted] you will usually get consistant grouping. Remember to shoot your sighters when you change tins. Its all play until you find the "Perfect"one.

Trailryder, this pellet sizer is not the best that one can use. The video is well made, and the sizer is quality as well, but this sizer has one flaw and drawback. It sizes the head and the skirt the same size, which is generally considered undesirable. 
Check out the TR Robb pellet sizer, it sizes the head smaller than the skirts. I have a video on it on my Field Target Tech Channel.

I use the TR Robb sizer it’s very easy to readjust for different pellets it has a tapered hole where you can control the depth the pellet goes to allowing the skirt to remain larger than the head. All of the other compression sizer make the head and skirt the same so you need to add an additional step to enlarge the tail end.

Oh, right. I knew that. I saw that it was sizing head and skirt the same, it just didn't click. Think I was just impressed with how quickly you could do a handful, that fact blew right past me.

I've seen the video of the TR Robb sizer.

And I would like to see the video because I left and looked then came back to comment that I could not find it using several different search terms.

A link would be nice.

And it sounds like what I would like to buy... If someone would be so kind as to point me to a link for that too (I'm just getting tired of searching time after time from hints where I spend an unproductive hour and give up. Too much garbage to wade through anymore
I copied "Field Target Tech Channel Tom Holland " and pasted it into the search bar and it told me 'not found'

Kinetic, here is the link:

Thank you, Tom.

Update, I watched the video and have subscribed.
Thank you for making them, I see I shall watch them all eventually as I never stop trying to improve myself and can see I can with you.

Kinetic,
Glad to see you and many other shooters finding them informative and useful. That's the most satisfying part of the vids. New camera, better quality video in the future, along with varied content. There will be something for everyone.

I thought that the sizers really only sized the skirts. At least that is what my Beeman one does when looked at under a magnifying glass. Maybe, it is the die that I am using is larger than the head. Once you size the skirt to a uniform size, then you can use the glass pane to see which ones are curve out of sync due to head size differences. 

I do know that sizing the H&N Snipe Mediums works well for my daughter's 1720, but really drops velocity on JSB Monsters in my Brocock Bantam.
