Crown/Impact Settings?

[michael23]

Just curious what everyone's starting points for tuning and finding highest amount of accuracy are? I understand each gun is slightly different but you would think a 600mm barrel with lets say a 600mm slug A barrel liner, reg set at 135, power setting 3 out of 2 stock guns would have similar results with the exact same pellet or slug? Here are what my go to settings/ammo have been so far...

Gun: Fx Crown .22

Barrel: 600mm

Reg: 135

Pellet/liner: JSB 18.1, power setting 1... stx liner

Pellet/liner: JSB Hades, power setting min... stx liner

Slug/liner: 23 grain .218, power setting 2... slug A liner

Slug/liner: 27 grain .218, power setting 3... slug A liner

What does everyone else use?

You left out your velocity.

My guess is the 23 and 27gr slugs are going "slow" at that reg pressure.

Agree with Bob. You need a chrony straight off. You can't tune these or any gun without that. Go into search and find Bob_O's video's you'll find what you need to know.

Any suggestions on a decent chrony to get?

I use a Competition Electronics Pro Chrono.....fairly inexpensive and works just fine. I also have e the Digital Link for it so I can make charts when I want to.

But if I were to buy one now, I'd get a magneto speed, or other kind that attaches to the barrel.

+1 on the Magneto. The v3 model is suppose to handle airgun shots better than the predecessor. Mine should arrive today or tomorrow, replacing the EdGun mini-chrono that I've been using to tune indoors with. I'm still planning to keep my LabRadar though.
