oak 3 Posted May 13, 2005 Report Share Posted May 13, 2005 What markings will tell me if my 19" bbl non-threaded Saiga 12 is full choke (or not)? What markings tell this? Other than the usual Saiga markings it has 18,3 on it. Is this it? What does this mean? Quote Link to post Share on other sites

Jeric 0 Posted May 13, 2005 Report Share Posted May 13, 2005 I beleive that the F(1.0) means full choke. Mine is stamped with that just below the 18,3, if yours isn't, I'm not sure where you'd look. If yours has F(something else), then at least you could deduct that you do not have a full choke. Any one have a more comprehensive interpretation of the F() markings?

Jeric <{POST_SNAPBACK}> There's a list of the choke sizes and the corresponding F() markings in the owner's manual. Quote Link to post Share on other sites
G O B 3,516 Posted May 13, 2005 Report Share Posted May 13, 2005 The F(1.0) means full choke. G O B Quote Link to post Share on other sites
oak 3 Posted May 14, 2005 Author Report Share Posted May 14, 2005 (edited) There is no F on it. Only 12X76 18,3. That's it. Nothing below it. Hmmmm? Anyone have any input? Edited May 14, 2005 by oak Quote Link to post Share on other sites
IndyArms 10,186 Posted May 14, 2005 Report Share Posted May 14, 2005 If you can mic the ID of the barrel, we can prolly tell you the choke spec.... Quote Link to post Share on other sites
oak 3 Posted May 14, 2005 Author Report Share Posted May 14, 2005 Thanks Indy, I will mic it later tonight and post it. Quote Link to post Share on other sites
oak 3 Posted May 14, 2005 Author Report Share Posted May 14, 2005 Ok. So here it is---- 0.718" is the inner diameter. What do you think it is? Quote Link to post Share on other sites
IndyArms 10,186 Posted May 14, 2005 Report Share Posted May 14, 2005 Ok... I would consider full to be about .705 ( give or take a few thousandths), and a modified to be about .725 (again, give or take a little) so... I would say you have a full choke! or at least a fuller than modified choke. LOL Thats going with pretty much standard 12 gauge numbers. I would say for all intents and purposes... FULL CHOKE If someone else has more accurate dims for the saigas.. by all means *PLEASE* correct me... Quote Link to post Share on other sites
oak 3 Posted May 14, 2005 Author Report Share Posted May 14, 2005 That's what I was thinking. At about 30 yards it holds about a 3 foot pattern. Thanks for the info Indy. I appreciate it. Quote Link to post Share on other sites
Integratedj 1 Posted May 14, 2005 Report Share Posted May 14, 2005 My 19in threaded model is cylinder bore, and only has 18,3 on it. IJ Quote Link to post Share on other sites
Bvamp 604 Posted May 14, 2005 Report Share Posted May 14, 2005 my 18.5" has the F(1,0) full choke marking, but a dime drops down the muzzle, meaning the marking means zilch on my gun. mine is a cut 22" or something. i dont think my shop cut it back, and im curious if the importer or factory might have done this........

IndyArms 10,186 Posted May 14, 2005 Report Share Posted May 14, 2005 I just mic'd out a dime.... its 0.700 So if your barrel is .715... yeah, a dime will drop down it... NOW.... on my 22" barreled S12... the dime *WILL NOT FIT* and it is a TRUE full choke, but is probably closer to EXTRA FULL as far as a sportsman consideration.. as I would say its closer to .695 or the like... with the brake on the end I cant really mic the barrel ID easily... and no, I dont feel like pulling the brake off. typical hunting shotguns would consider a .705 a full choke, a .695 or less EXTRA FULL... in fact... my MOSSBERG with the XX-FULL turkey choke is a .670... now that baby is TIGHT!!!!!! Take all this as you will... and call it what you will... it is ALL ARBITRARY.. yopu know the diameter of your barrel, you know how and where it patterns.. *THIS* is what is important... *WILL YOU HIT WHAT YOU SHOOT, AT THE RANGE YOU ARE SHOOTING???* nuff said..

crusty 9 Posted May 15, 2005 Report Share Posted May 15, 2005 Gidday from New Zealand! I've been checking out the forum for a couple of months now, thought I should join in. 18,3 is 18.3mm = .720" so must be full choke. I like my Saiga cos when I miss the first clay bird the other 4 rounds just seem to go all by themselves! Quote Link to post Share on other sites
oak 3 Posted May 15, 2005 Author Report Share Posted May 15, 2005 Thanks for the info crusty. I knew those numbers had to mean something. Quote Link to post Share on other sites
kmoore 3 Posted May 16, 2005 Report Share Posted May 16, 2005 (edited) Usually, choke is measured as a constiction. So it depends on the diameter of the bbl, and diff manufactures use different diameters. (there's no standard. Back bored, overbored, etc bbls are done) Here's a link to the measuring that I had done a while back. bbl dimensions In the mean time, I cut my bbl back, I was looking for a "less full" choke. Here are the details: original was the 22 inch. When I stuck my finger in, I could feel a ring of constriction a bit back from the muzzle (~3/4 of an inch). (yes, it was empty!) I was trying to get a modified choke out of the bbl, without screw choking it. I cut ~ 1/2 inch off, and miked it The ID was unchanged (maybe 1 or 2 thousanths). Cut ~1/4 of an inch. This was around the region that I felt was where a lot of the constriction was realized. The ID opened up quite a bit (can't remember now, but something like .7ish. I can check when I get another chance. Most importantly (to me) was it gave me the performance that I wanted (tight enough to know over steel at tactickle matches, but open enough to bust clays by pointing, not aiming, and at "speed"). I haven't dressed the muzzle up yet (I didn't know if I'd need to cut more) and it's not high on my priority list, but I'll do it someday. It's not needed (IMO).

kmoore 3 Posted May 16, 2005 Report Share Posted May 16, 2005 BTW, Mickporno did cut about all he could from his bbl (cut back and permanently attached his flash suppressor, probably ~17 inches?). He's having choke tubes put in it now because the pattern is just too loose. It was very fun while it lasted. His measurement was .720 for a while, I think he went thru another round of shortening and so it might be even more loose. Anyway, proceed with caution. Nothing more fun to watch than his dealings with the Texas Stars that are used in some competitions around here. If you don't know what one is, think of a stubborn piece of steel that has to be detached from an arm. One course of fire specified that you had to use a shotgun till you ran out of ammo, then if you still didn't knock all of the plates off, you could transition to a sidearm. Mick thru about 3 mags (9 rounds each) at them and I think 1 or 2 (of the five) plates popped off. You could see the plates getting pelleted (sorry for the pun) and rocking but just not popping off. He shot fast and furious, but when it was done he still needed to go to his Glock (it's ok, he had a 33 round mag in that one! lol). On the up side, I've seen him bust 3 or 4 pigeons at once (pigeons are stationary, placed on stands or the hill). Othertimes you could see his pattern hit the berm, seemed like he had a 4 foot pattern. Even I can't miss with that! Anyways, HTH Quote Link to post Share on other sites
