So I put in an order last night with AVS Slugs to have ammo here when my GK1 arrives next week. I got a text this morning from one of the owners asking me if my order was for a Huben GK1. I ended up chatting on the phone with him for a while, really nice guy. He has a GK1 and was measuring the groove diameters of the magazine and barrel. He found they are off by 0.00285". So the magazine is larger than the barrel at about 0.2236" with the barrel around 0.22075". So he actually suggested I try out 221 ammo along with the 223 I ordered, and we changed some weights on my order for the best performance. So I now have 221 ammo on the way I will most likely be a lot happier with.
He also mentioned that they make their slugs with pure lead as opposed to adding hardeners like a lot of the large companies use in mass production. Because of that the rifling bites into the pellets better, but you may notice some lead dust if shooting 223 due to the barrel being slightly smaller than the magazine.
I have a feeling this info is going to be pretty useful for some of you, so I thought while the conversation is still fresh in my head I would post this here.
I am in no way affiliated with AVS and am not getting compensated for anything, but I recognized pretty quickly that these are people who actually care about what they sell and are doing their best to put out a quality product. Unless you are placing 6 figure orders with most of these large companies I dont think anyone will ever care if you are happy or call you. It was really nice to actually have found a good small business manufacturing specialty ammo like this. He said they are also going to have more sizes between the 221 and 223 in the future. The suggestion to order from AVS actually came from this thread I created a couple of days ago BTW, https://www.airgunnation.com/threads/huben-gk1-v3r-heaviest-ammo.1305960/
I'll update this thread with the performance of these slugs I receive.
