Are the heavy shot choke tubes necessary or is this just a sales pitch. I shot heavy shot last year and might shoot it again this year.

Depends on who you talk to. The reps I know who work at Kicks Gobblin thunder tubes say they wouldn't shoot hevishot thru anything tighter than .670. the remington engineers i talked with said they wouldn't shoot it thru anything tighter than a .680. i understood where they were coming from and i still shot my hevishot through a tube as small as a hastings .636 up to a regular remington rem choke full .680. i knew i was taking a bit of a "risk" - but i also knew i wanted to find out for myself what would be the best tube for hevishot. as i've said on here before, my data (certainly not perfect - but hopefully consistent) suggests that out of a 12ga - the hevishot 3" 6's seem to prefer a tube inthe range of .665 to .670.
the hevishot 3" 4's seem to prefer a tube inthe range of .675 to .679.
That's why i would recommend to EVERYONE that BEFORE you buy any choke tube - know the constriction first...better yet, invest $40 to buy your own digital mic/caliper and measure the tubes yourself...you'd be amazed at how "off" the exact measurements are from the measurements advertised. one more thing...the measurement 1/2" down in the tube from the muzzle end will likely be a different measurement too fromthe measurement at the muzzle....but that's another disucssion altogether. |

Diablo where can i buy a .636 choke tube?? in a 835 the HVshot does not like anything under .680 with #6's i shoot 3.5's in all shot sizes, also the the MAD tube is the answer at 35+ yds with both W-W & Rem HVS. Just for though have you tryed a old cleaning brush and rod, 00 steelwool and a drill, you will also need some inside mics. But by removing .001/.002 at a time from the choke only not the barrel it will make the difference, i do this on every shooting match barrel i've ever shot. |

Hastings makes all kinds of tubes. but let me clarify...the hastings tubes i referenced in my earlier post are NOT made specifically for hevishot...but i tried em anyway.
Hastings tubes can be bought online...try these sites:

I'll be using the drill and steelwool.scotchbrite pads this weekend...close friend called me yesterday coz he did it too...his pattern was good before he used the drill on it...his pattern was awesome after he used the drill...hopefully he'll post his results on this thread

I went back to an APtril post from last year and just copied itand put it here for anybody interested in cleaning up their barrels and getting better patterns: here is some information from a fellow named John Coit, from South Carolina I believe, that everyone might wish to consider for their turkey gun: ""I think you can pull somemore serious potential out of your gun with a little bore polishing.
Polishing the bore:
cleaning rod
bore brush
scotchbrite pad
wd40
gun cleaning solvent
patches
3/8 drill
Thoroughly clean the barrel removing all fouling wipe dry with dry patches
cut your scotch brite pad so it will encompass the bore brush and cover the bristles entirely.
lube the barrel and scotch brite pad with liberal amounts of wd 40
with cleaning rod attached to your drill work the scotch brite covered bore brush into the back of the barrel slow turning of the drill greatly eases this.
On high speed run the drill and bore brush up and down the barrel stopping at the joint where the choke meets the barrel ( measure it first and mark the rod with some tape so you know where to stop. You want to polish the joint but not run the pad out of the end of the choke. Make sure you keep that brush moving up and down the barrel and do not overlook polishing the back of the bore as well. In between scotch brite pad changes swab with a clean patch and check progress what your looking for is an absolutely smooth glass finish with no ridges pits or scoring marks. In most cases twenty minutes and one pad change in between will leave you with a substantially smoother and better shooting shot gun.
I have yet to do a factory barrel that didnt improve patterns by at least 25%
Before you shoot the gun make sure you swab out the barrel and put a light coat of oil in the barrel. Shoot the gun re oil and then you can go back to your normal maintainence routine.
Why does it work? well heres the theroy as it was told to me . As the shot wad travels down the barrel it encounters friction with the barrel. Any imperfection in the barrel acts as a drag on the wad slowing it down. As this happens your shot charge does not slow down and the shot string length gets longer. When the shot encounters the choke you are actually choking less shot than the choke is designed to handle and choking it in varied densities causing fliers and holes in the pattern. What you want is the shot string to be as short as possible when it encounters the choke. Smoothing the barrel helps to accomplish this.Ideally you would want your shot to all be in the wad until it encounters the wad stripper in the choke. One thing Ive noticed is after polishing the average gun handles the hevier shot charges better than before. thus giving you more pellets out there and even higher hit counts.
I can tell you this much polishing the bores of these shotguns around here had a more dramatic affect in desinty and hit improvement than any of the aftermarket chokes or shells Ive tried. Combined with thes aftermarket products though the improvements are truely amazing. When you can put an entire pattern of 5's into a 10 inch circle at 30 yards youve got an absolutely deadly turkey gun all the way out to 40 without a doubt.
Hope this helps.Let me know how it works for you if you try it."
