HDAV Posted September 13, 2012 Report Share Posted September 13, 2012 He certainly opened them up, but he didn't finish the job off, well not on that clip anyway, no fine polishing I've just had two Teague Chokes opened up to the size I wanted for my gun, my friend who's a superb engineer did them on his CNC to the original tapered profile then finely hand polished internally Azzurri Re-profiling a screw in choke is different to opening up a fixed choke as I said I have no idea how long it takes and i am certain that the video was edited down. I recently changed my standard standard choking from 1/4 & 3/8 to 1/2 & 3/4 (MC gun) better breaks and i don't think any more misses.... If they were birds not clays then this may be better for the clean kill but not so good for the table.... and this is with 28g 7.5 clay loads.....

seeker Posted September 13, 2012 Report Share Posted September 13, 2012 BASC did some testing on chokes and patterns .... http://www.basc.org.uk/en/utilities/document-summary.cfm/docid/14C9E34E-6F19-47F3-9AD65ADFC04125A4 Quote Link to comment Share on other sites More sharing options...
Azzurri Posted September 13, 2012 Report Share Posted September 13, 2012 I wouldn't let that guy loose on my gun, even if the vid was edited down, I could do as good a job with a brace & bit... Of course you're getting better kills on the clays, you're using more choke... As for shooting game with 7.5s, you are joking aren't you, they'd only tickle birds that are worth shooting ;-) Quote Link to comment Share on other sites More sharing options...
HDAV Posted September 13, 2012 Report Share Posted September 13, 2012 As for shooting game with 7.5s, you are joking aren't you, they'd only tickle birds that are worth shooting ;-) It was the perceived lack of extra misses .......and i only mentioned the load as when talking chokes its important.....the pattern with 32g or 5/6 may be totally different.

Azzurri Posted September 13, 2012 Report Share Posted September 13, 2012 I suspect the pattern may not be all that different, open choke = open patterns, simples...may be fine for those walk about days when you may as well be shooting chickens, but on the tall stuff you can't beat full choke (or just under) and a BIG load :-) Quote Link to comment Share on other sites More sharing options...
bigman Posted September 13, 2012 Author Report Share Posted September 13, 2012 Well this is good interesting stuff but feel like my heads getting more clouded , so to go out and pattern my gun properly sounds like the thing to be doing , but how to do it properly and what to expect ie spread size at 30y etc , last time i did it i just popped at some sheets of ply down the yard at 30ys , to be fair i was suprised by how large a area it covered from either barrel , the best cart out of what i had that patterned tight was some pro ones 7.5 28g plastic ,quite dense in the centre of the pattern much bigger spread from the kents 6 29g fibre , also tryed some buffalo BB 36g and to be fair the pattern really didnt look to shabby not many holes in the pattern if that makes sense Quote Link to comment Share on other sites More sharing options...
Harnser Posted September 13, 2012 Report Share Posted September 13, 2012 I think that there is to much talk about choke sizers . Many ,many years ago I bought a side by side gun that was half and full choke . Being a comparitivly new boy to shooting at that time Iwas advised to leave it as it was and to see how I got on with it before having it opened up . I shot with this gun for about five years and managed very well with it . The gun was used for every thing ,wild fowling ,pigeon shooting and driven game as well as a bit of clay shooting ,it looked like half and full chokes was the best choice for me . Any how ,I decided to part exchange the gun for another one as I felt I wanted a change . When I did the deal on my new gun the gun shop measured the bores in my old gun and they were found to be cylinder and quarter choke . I had used the gun for five years thinking that it was bored half and full and it was cylinder and quarter choke . I think that this choke thing is all in the mind . I would stick with the chokes that are in the gun . Harnser , Quote Link to comment Share on other sites More sharing options...

Harnser , +1 again, it saves you money ignoring the chokes. regaurdless of whats stamped on the gun, are those chokes actually what they are. ? my german gun is stamped 1/2 and 1/1, but the actual specs are 3/4 and xfull. so what they guy thinks he has and what he actually has are two different things. in hindsite i should have ordered a more open choked gun, but i`ve a classic bird gun, for firing small shot thats actually choked very nice. ps, having the chokes mesured will cost money, and i`m not talking about a cowboy chucking a brass gauge in the end, first the mesure the bore, then the restriction, then they calculate the restriction / choke. so ignore the issue, just concentrate on shooting.

coyotemaster Posted September 14, 2012 Report Share Posted September 14, 2012 I read once that most shotgunners are choked to death, a pun obviously, but much truth in it. The same writer who was also a good shooter(not mutually exclusive) had an autoloader with a barrel marked full that he had reamed out to IC for Dove shooting. Anyone that borrowed that gun claimed it was the hardest shooting gun they ever used. It was just that they could hit more birds ith the advantage of a much larger pattern, mind the fact that doves aren't particularly hard to kill.

Hamster Posted September 14, 2012 Report Share Posted September 14, 2012 I once had a choke altered when the smith simply took it into his back room and returned moments later having he said hand reamed the 3/4 top barrel of my Miroku 6000 G3 down to 1/2 ! It was well over twenty years ago and I just assumed that's what you did. A few years ago I bought a Browning XT Trap on the phone but the chap wasn't impressed when I suggested he just ream them out from 3/4 & Full to 1/2 & 3/4 for free as it was such an easy thing to do he insisted I pay at least £60 for the pair. Azzuri, I wasn't aware you could open up multi chokes. Quote Link to comment Share on other sites More sharing options...
wymberley Posted September 14, 2012 Report Share Posted September 14, 2012 If the gun is actually patterning anywhere near the nominal choke dimensions that you have posted, then a concentration of shot in the pattern centre is to be expected (Gauss) You really don't want to know what size the spread should be because if you do know, that's what you'll find - it's like a rifle shooter chasing the error. If you're going to, pattern it first, look at the results and only then look at the tables to determine what you have. Quote Link to comment Share on other sites More sharing options...

It was just that they could hit more birds ith the advantage of a much larger pattern, mind the fact that doves aren't particularly hard to kill. oh yeah, most bird guns here are choked to death, or atleast started life that way. most are designed for game shooting, on a peg, with driven birds. game can be taken at 80 yards or more. it is far far away from the traditions in america for shooting over dogs, at sub 20 yards. if i did that i`d use cyl chokes. now having pot shots at pigeon can be fun. now the everyday phesents here are flushed in your face, and the extreme targets of yesteryear are usually really expensive or the reputation for "high birds". they even have specialised shells for it, such as super high game in a 2.5" shell, 1,1/16oz 5-6. (not so high bird) and the black gold, 36gram, 1,1/4 oz #4 for driven game at 1500fps. - for the extreme game shooting. the next manufacturers equivalent would be the same, still in the 2.5" case. with a slightly wider range of shot but 4-5-6 only. so by far we are shooting 1oz to 1,1/8oz loads and usually small #6 UK thats about #7US (or very close.) so choking is compensating such small payloads. in a recent poll of the game shells, only one used 36g and #4s the rest was 30grams of #6 Quote Link to comment Share on other sites More sharing options...
wymberley Posted September 14, 2012 Report Share Posted September 14, 2012 game can be taken at 80 yards or more. What choke/cartridge would be used for that? the extreme targets of yesteryear are usually really expensive or the reputation for "high birds". I was under the impression that the extremity of the distance of any game shot was related to the limit in performance of either a Grand Prix or Impax cartridge being as they were the only two alternatives readily available.

bigman Posted September 14, 2012 Author Report Share Posted September 14, 2012 Anybody ever shoot at lakenheath clay ground? i sometimes go down there it would be nice to meet up with somebody more experenced that could run there eye over what i doing ? cheers Quote Link to comment Share on other sites More sharing options...
Guest cookoff013 Posted September 15, 2012 Report Share Posted September 15, 2012 no,the targets are not set due to what cartridges can do. usually its presentation. some of the trying targets can be simple. @big man, i shoot lakenheath now and again. give me a yell.
