Bullet sizing nonsense, AEA and Huben

[BeeHavior]

So, after firing a Huben GK1 Mk II and having it self destruct it came back from the repair shop. Great experience with Kraz, receipt below.

Part of the issue was the .25 ammo was undersized, which had it shooting soft and eventually led to a jam in the barrel. Taking a follow up after the jam was when the magazine release lever flew off.

So, it's been shipped back with 500 AVSslugs .2533 44 grain slugs with a cupped base -- also pictured. These are the smoothest and most precise pure lead bullets I've ever held. First shot on a full tank was 884 FPS!

----------------------------------------

So, the right bullets make all the difference. Now I want AVSslugs for my AEA SF .30

You can tell AEA guns are made by people that don't know guns. My SF Sniper has 7.62 stamped on it, but actually firing 7.62 /.308 cal slugs led to a nasty jam. They were too big. I don't have tools to slug the barrel, but I read in a comment somewhere that .303 is the way to go and those at least shoot and cycle correctly.

AVS has .303 in four base styles - flat, cup, dish, and cone. I can also get a range of custom weights ranging from 45 grain on out to 100. That's hundreds of variations! I'm not sure how to find the perfect bullet fur my long barrel SF.

I'll update as this progresses. I'm probably going to email the owner of AVS, in addition to asking y'all for advice.

A person can save a lot of money and headaches by investing a minimal amount of money in barrel slugging tools:

99% of airgunners don't slug their barrels.

@BeeHavior You don’t need many tools to slug a barrel. A stiff rod should do the trick. It needs to be softer than steel or whatever you barrel/liner is made of. Preferably a wooden dowel, plastic, or carbon fiber rod. A micrometer helps a lot, but you should be able to get by with a decent set of calipers to measure the raised groove impressions on the slugged projectile.

Now if you lack the tools or understanding of how to remove your barrel from your airgun, that’s different. Huben air guns are a little different because the magazine chamber size(s) may not match the barrel diameter (there can be slight variances). There are people that will argue this isn’t an issue for them, but from reading your post you’re one who has experienced loose ammo in the mag.

I’m not sure what “MKII” means. Your paperwork in the photo says you have a GK1 V3. There are many threads on this air pistol. I suggest reading through some of the discussions on ammo selection and what others have experienced.

Oop, you're right about the V3. As I understand I got an improved V3 mag release lever and that was on my mind as I wrote this up.

I'll borrow a micrometer and give it a go once I confirm I can get the barrel off and on without goofing something up.

@BeeHavior If in doubt drop in and ask questions. I think you’ll get it.

if your shooting slugs the very best money can buy are BARS slugs. https://www.facebook.com/bars.523253#
