[chasdicapua]

Anyone know the max length slug that can fit into a 2020 .25 Huben magazine?

Chas, 

Call New England Air Guns. John is a distributor, and should be able to help.

I figured John or Kelly would know. I thought I would try to see if anyone on the forum knew before I bugged one of them. 

Thanks for the number.

Please let us (me) know if it has changed from the 11mm ( 0.4330) as per the pre/2020 .22 versions.

SO you got yer hands on a 2020.25, I thought I also would have one by now, did not happen, please post lots of your findings so I can live the experience (vicariously), 

thanks.

Ah, 11mm. The 2020 magazine looks the same, but I'll check with Kelly or John to be sure it's still that depth. If so, that would make the largest NSA 55gr slug at .485 in length too long. I was hoping to see what the K1 could do with that. 

With the current power wheel setting (I haven't touched it yet) and the regulator on 19mpa, it's shooting the JSB Heavies at 1045fps for 82fpe. I've got some 47gr Griffin slugs coming. Hope they will fit the magazine. If not, the NSA 43.5gr slugs will. They are .39 ish. I'll post some more number when I get the heavier projectiles. 

Very accurate. I'm hitting a 6" steel plate at 110 yards with a red dot on it!

As I understand it the PRE 2020 .25 had mag holes with a diameter of .254 (6.46*) and that Stephen of AVS fame makes .254 slugs in various weights** in flat,dish,cup,hollow base, assuming that the mag (or barrel diameter) has not changed these should fit.

**weights, I am as yet not sure at what point Stephens .254 slugs become longer than 11mm.

I am SUPER interested in the 2020 barrel, the PRE did not shoot slugs* that well, I was told that Huben where putting a lot of effort into sorting this on the 2020 version.

What's AVS stand for? Would be good to have another slug source.

Air Velocity Sport, Stephen knows his stuff. (you will know him when you see him) his YT videos are great.

OPPS, Stephen (AVS) has replied to a question I asked regards weights, he indeed gives all that info, it is contained in a small rectangular pic that you can just click on.

don't buy the boat tail AVS .254

they are to long for the magazine. I bought the 42 grain dish and they fit snug and are not to long. have not shot them yet.
