What pistol did you shoot today

Dug up my 1701, from 2021 (new out of box for the most part, minus the custom grips and sights). Shooting Predator GTOs (6.79gr). Was not satisfied with avg speeds of 505fps, so after increasing the spring load by 3.5 turns (no idea what it was set to out of the box/new)… am a happy camper at consistency of ~550fps (10shots, btwn ~2800psi-2600psi). She’s a keeper.

(Ignore the ft-lbs data in the shot count; was too lazy to change the pellet weight.

All 10 shots at 5yd; standing/two-handed.)

The Gamo BBs are indeed lead. Unfortunately they jam like crazy in my Luger so I’m not able to do any tests with them.
I did get the 4.5mm steel BBs today and gave them a go. No appreciable improvement in accuracy, and only a 5fps increase in fps.

So far, the best groups I’ve seen have been with the plastic ASG BBs
Just tried some Barra zinc plated BBs. These yield the best accuracy yet. Actually pretty decent.
They're about 0.001" larger in diameter than the Black Diamonds or AGS.
Perhaps the tighter fit in the barrel helps?

The 65 is a masterpiece of engineering. Every time I pick it up I’m amazed at how effective that recoil slide works. And correct me if I’m wrong … it uses metal piston rings.
