What did you do airgun related today.

I learned about the importance of harmonics in tuning today. Been struggling to get my Impact m3 completely dialed in, but today a light bulb 
went off and I tuned my gun for the first time based on harmonics and it’s performing amazingly. What a fun/educational journey it’s been!!

What are your interests . plinking in the yard ? paper targets ? pesting ? nice if you show up every day ? that's a nice way to get your 10 days in .

I took an opportunity while my kid was taking a nap to zero and shoot a 30y challenge target. While I was doing this a squirrel started raiding my bird feeder. The ol 177 is pretty flat and I took the opportunity at the squirrel 20y away. Video didn’t get the shot, but soon after.

I gathered sorted and sized my .22 slugs .25 up next time. Made sure I marked the tins this time LOL

Those .22 slugs shoud do well in your P-Force.I gathered sorted and sized my .22 slugs .25 up next time. Made sure I marked the tins this time LOL

Harmonics enlightened me. OldVet wants to know. I'm not ashamed to learn.I learned about the importance of harmonics in tuning today. Been struggling to get my Impact m3 completely dialed in, but today a light bulb

what?! What a strange form of communication you have here. Are you saying you already know, or are you saying you want to learn??

I’m guessing that like me, he’d like some enlightenment as to your methodology. I’m a dry sponge when it comes to tuning these things.

I made a post about it in the PCP section, but I can give you a quick rundown here. And @OldVet I’ll tag you as well so you can see it.
I’ve been learning everything about air guns from scratch this year and have been trying to tune my guns to shoot at my desired speeds. I would pick a speed that I wanted to shoot at and then basically tune the gun from the ground up to achieve that speed. There is a few problems doing that way one is that there’s multiple ways to achieve the same speed depending on your gun. You can go with a higher regulator setting and a softer hammer strike, or you can go with a lower regulator pressure and a hard hammer strike, both can achieve the same speed, but the air delivery will be slightly different for each.
That being said I did some research on the pellet I was shooting to find out what speeds it shoots best at. I determined that I wanted to be somewhere between 825 and 925 fps. I tuned my gun to give me a peak velocity of roughly 925 ft./s from there. I shot three shot groups while decreasing my hammer one click at a time. That process may be different on your guns, but essentially you can decrease the hammer and fire three shot groups and note how tight the groups are.
As an example I shot three shots at my peak velocity setting and then dialed back my hammer and took three more shots. I kept taking three shot groups while backing off on my hammer, noting how tight the groups were at each setting.
Once I found the setting that gave me the tightest most consistent groups I pecked around that speed to see if I could further increase the accuracy. I really fine tuned my gun around the speed that gave me the best accuracy instead of trying to make the gun accurate at the speed I predetermined. I let the gun tell me what speed to shoot it at.
There’s also a great video from Matt Dubber where he explains gun harmonics, but I can’t find the link to that video. Good luck and let me know if you have any questions.

I've been giving the AV grips on my 1701P a cleanup with 1000 grit emery cloth and hitting them with some tung oil. Cocobolo is beautiful wood!

Finally drying out after a week of rain, may be I can target shot today. Any way, I spent last week finalizing my action block design for the next project.

Shot and sighted in my " New 2 Me" .25 cal Leshiy 2 and pellet tested it to see what it likes best. So far it eats everything I throw into it very well. Quarter size groups at 40yrds. Gonna tighten that up with a few tweaks to my scope.

I'm sorry I did not mean to be so confusing. What I should have written was. Can you please teach me about harmonics tuning. And you did send a video thanks.

Ohhhh... Ya made me take some pics. Hard to capture the depth with a cell phone, but here ya go:
