I was able to squeeze in a solid hour of shooting today 🤘 I filmed all of it and I'll splice together some video later. Here are my initial findings:

DW - 4.1616633341.jpg




Rifle: Daystate Delta Wolf .25 caliber

Scope: Hawke Frontier 4-20x50 FFP

Rings: Sportsmatch Adjustable

Moderator: Huma Modular

Bipod: Accu-Tac

Targets: Splatterburst 

Pellets: JSB 34g MK1 & MK2, JSB 25g, H&N Barracuda Heavy 30g, H&N Barracuda Hunter 28g, Benjamin 28g

Settings: Chose nearest factory programmed weight, then set the desired velocity to 880 FPS and let the chronograph & GCU do the rest. On average it took about 3-5 shots for the GCU to match the velocity I asked for. It was able to "find" the velocity quicker going from light to heavy pellets, than from heavy to light.

Each group is a full magazine dump (10 shots). In order of best grouping: JSB 34g MK1, JSB 25g, H&N Barracuda Hunter 28g, JSB 34g MK2, Benjamin 28g, H&N Barracuda 30g

I'll cull some slugs next, then take the best pellets & slugs out to greater distance.

Cheers

Congrats and thanks for sharing initial pellet testing results. What distance were you shooting?

Oh sorry, 45y. Couldn't get to my 50y seat because some wasps had infested my shooting shack.

I should also mention that I did not do any barrel prep besides a few quick "pull-thru" patches. I like to see what the barrel will do from the factory before I polishing it.

Ban abbreviations --- GCU? --------------------- Gun's Computer Unit? --- Gun's Chrony Unit? ------------- Goofy Calculating Unit?

Good luck and good shooting, I only hope that no major improvements come along that make the first run models wanting for more. Not with what the original buyers paid for them anyhow. Personal mods are open territory.

I think it stands for Gun Control Unit. Sounds better than "the brains"!
