Hello all, I’m interested in getting a new extended choke tube for a 18.4 bore ( mics .724) Perazzi 34” barrel. I’m a 25 yard shooter who shoots rather fast. The question is : .030 or .035 constriction? Best regards, Rufus
Are you are referring to after-market choke tubes ????? If so ..... they are as individually unique as snowflakes ..... brand-X .030 may be better than brand-Y .035 in your barrel ..... the reverse may be true in a different barrel ..... So ..... without some money and time investment ..... it is just a guessing game ..... If it would be a factory Perazzi choke tube, and I didn't want both, I would purchase the .035 .....
I subscribe to the choke for smoke concept ..... to a degree, but the # 10 flush the barrel came with seeing the bore diameter is a bit tight in my opinion. I’m mainly interested in an extended as more of a muzzle protector.
First thing I would do is measure the bore completely, which you have. So many of these guns have had barrel work done to the point that no choke tube will be the same constriction measurement.as marked. As mentioned above, many choke tubes that are considered imp. mod., full, etc. are of different measurements. The only way to find true constriction is to subtract the choke constriction from the bore. As far as .030 vs. .035, you would have to pattern them to see what you have. Then a full analysis would then have to be done such as Shotgun-Insight to tell you the difference between the two. With that small of a difference between the constrictions, it would be very difficult to see the better pattern by just eyeing it. Tighter constriction does not necessarily mean better pattern either. Personally, if you are at the 25 yd. already, I would look at the tighter constriction. You are more than likely going to be moving back, hopefully. If you see a very nice pattern result after testing, leave it in for 16 yd., you may be surprised at the results. One more thing, make sure the extended tube in the barrel fits in your case. PITA to have to remove the choke to put it in the case. IMO, if you remove the tube, it should be cleaned, along with the barrel threads also, then fresh grease. If there is any plastic stuck on the flange of the choke area in the barrel or the tube when you screw it back in dirty, eventually it may flex that very thin area out into the bore. Also it makes the chances of dropping the choke tube better. If you drop a tube you have to make sure it is not bent in on the flange. Shooting a choke out of the barrel is very costly. I am old school, fixed choke barrels have one choke. If that pattern is good at 35-40 yds., it will be even better at 24-27 yds.
Rufus, .030 is plenty choke for even the 27 yd. line. But try different makes of shells. also try different loads. They all do not shoot the same out of different barrels. Roger C.
I think you can get hung up on choke, pattern is much more important. I had Tommy Wilkinson choke my handicap barrel, with a choke tube that he fixed in and it couldn't be taken out. He told me he did that so I wasn't f...ing with it. He was right. Most trap shooters screw with everything and choke tubes are a prime example. Play with your pattern, get one that is even and don't clump up in the pattern. You want an even pattern. Why a choke of the same bore and restriction would pattern different from another with the same bore and restriction, I don't know, but they do. Once you find that bbl keep it. I've had my Wilkinson bbl for over 30 years. I don't know who the good bbl guys are today. Brad
Rufus, On another note. I have .030 in my K-80 barrel. I stood on the 30 yd' line at Vernal and smoked 25 straight. I was using STS light handicap ammo. #8 shot Brad is correct pattern is more important than constriction. Roger C.
Don't get too hung up on .005" constriction. That .005" constriction is far less important than what those two chokes produce in YOUR gun, with YOUR loads. You have two choices: 1. Flip a coin. Buy that choke. Screw it in. Don't pattern it. Break targets with it. 2. Buy both. Pattern both. Choose the one that you think patterns best. Screw it in. Break targets with it.
I’m 100% with Roger!!! It doesn’t matter what name brand choke you decide on or what ammo you buy. Stick with the stuff that patterns the best out of your gun. Pattern your gun with good quality ammo and stick with that brand and load!!!
