Huben Huben GK1 V3R Heaviest Ammo

[TrollMagnet]

So I have a new to me Huben GK1 V3 22 on the way. I am looking to order ammo, but I am not sure what the best options are. I hear some ammo fits loose, and other ammo is too big. I figured I would ask here what the best options are for ultra accurate ammo of any weight, as well as the heaviest/largest ammo I can fit.

Can you all give me some suggestions please so when it arrives the ammo I have is the best I can fit? Thanks

If looking for slugs, I recommend the AVS dish .223.

The light ones will shoot a very accurate string through a whole mag:

Huben - GK1@100yards

After finding a sweet spot of very consistent speed with AVS 22-grain .223 dish slugs, I clamped my GK1 in the vice on my concrete table and shot at 100y in my backyard range. See post #200 in this thread for the background info...

And you can order some up to 40 grain that will shoot at around 70fpe at 300-350 bar. My guess is that you could alternate between the two without messing up the leading of the barrel and needing to clean, as you might if you switch between pellets and slugs.

There are many other that shoot well, but beware of undersized slugs.

Thank for that. So the 40grain AVS Dish 223 will fit fine in the magazine, but the lighter ones shoot better?

And what do you mean by messing up the leading of the barrel?

Yes and yes. Heavy slugs drop in speed with every shot, changing POI. Plus, these guns shoot more consistently at higher speeds. Finally, heavy ammo gives a lot more muzzle flip and that doesn’t jive well with a heavy slug that takes longer to leave the barrel.

Projectiles deposit lead in the barrel and settle into a groove in terms of accuracy. However, different projectiles use different compositions of lead. You can get a nice groove going with one projectile, switch to another and then return to the original and find that it no longer shoots well unless you clean the barrel. My point was that AVS slugs are likely all made from the same composition of lead, reducing likelihood of such “cross-fouling”

Thanks. I got the regulated V3R on the way, so I am hoping it stays consistent with heavy rounds.

I doubt that will work with a tiny plenum. Do you have time to switch it?

Quality over size. I would rather be shooting 30 or 36 grain consistently then 40 grain where i have to account for how many shots i have taken affecting trajectory

Please let us know how it works out.

@modos Could you please move this post in the right section? GK1 is a pistol
