Jug Choking

[steg]

I'm considering Jug Choking a .410 cylinder bore to tighten up the pattern, they do work and I've done it before. What I'm wondering is, will it have any adverse effects when 000 buck is used. Anyone have any ideas on the outcome?...steg

I don't have a direct answer for you. I too am aware jug choking works as my best friend Billy Doss (now deceased) used to do it a lot and we found it to tighten up patterns nicely.

I guess my consternation is why the heck would you use OOO buck in a .410? What can you fit in a hull three maybe? I doubt it would do any damage to gun or buck shot but I cannot imagine that degree of choke in a .410 is going to help or hurt the pattern if you can call it that of 000 buck.

Personally I never use larger than size 8 shot in a .410 nor do I use 3" shells. I realize lots of others do I've just never seen a real world improvement with the 3" over 2.5" shells or a purpose in my use of it that requires larger than #8 shot. The vast majority of what I shoot is #9 with some #8-1/2 sporting clays factory loads as well. All I load is #9 the other two are factory ammo only when I use them.

Just theorizing here - I would think that it would depend a lot on the cup the Buck was loaded in. A slit cup, the alignment of the pellets would maybe be messed up, but could come back when the choke was reached - or not, depending on how far overbore the barrel was bored.  An unslit ot partially slit cup, probably wouldn't have much effect on the Buck load. In other words, I don't really know, those are just a couple of thoughts.

That's what I was looking for a couple of thoughts, And Graybeard, I'm just doing it for fun, all I use is 2 1/2" hulls also, the gun I'm thinking about doing this to is a Ducktown, one of the strangest guns I've ever seen, but it's loads of fun to shoot, I was just looking to expand it's capabilities somewhat....steg

Around here a jug choke is used when you have open bbls like when someone cut off a long gun to make a bird gun or such . But the biggest market for it is turkey shoot guns , Here most shoots will not allow screw in tubes so to get a tight choke you relieve the bbl in front of the choke area. the shot expands and compresses then enters the fixed choke . With small shot it works well . With buck that dosent fit the bbl or can pack like fine shot it would seen all that would happen is you create and area where the over powder wad would be to small and let gas pass by to disrupt the shot as it leaves the bbl.

Shootall, that could be a problem, but I was thinking of going .30 , giving me roughly 15 thousandths per side to fill when firing it, and using a factory wad they have a small skirt on the base that should fill the void for the time it takes the buckshot to pass over it, does this seem like it might work? I really want to tighten up the improved cylinder bore some, but I don't want to give up the fun of firing buckshot either. Even if it was distorted, do you think it would be that bad of a distortion? ........steg

I think if you could find someone to add screw in chokes you would be better but that is a big cost. I don't think a jug choke would hurt you to much really as most 410 bbls are somewhat thick. .30 is alot though , might start with less and try until you hit the sweet spot . It dosen't take alot as in turkey shoot guns often its done with a hone not a reamer. the ends are sloped like a forcing cone or the begining of a choke.

[steg]

I was planning on using a hone, and 30 thousandths would probably be the max, I'll be patterning at every time that I guess I hit around 5 thousandths, and I want to thank you for your input................steg

keep in mind the difference in cyl. bore of a 12 ga. .729 to full choke is only .035 .
I would mike the bore / choke and then make the jug choke cut to match or at least have a starting point.
I don't know the constriction for .410 but 12 ga. is -
full .035 , mod .019 , imp cyl .009 .
I have some tubes that are in the .690 range and a bit tighter.

I don't have the gun handy right now, but as I remember it miked out at .432, I remember because someone asked if a 45 Long Colt could be fired in any .410, and that made me curious as to the Id of my barrel, I wonder if any .410's were ruined by people trying to fire 45 long colt's in them?.................steg

I've heard of 41 mag cases loaded light and used but that was hear say and i would not try it .
