MissionaryMike Posted July 6, 2016 Share Posted July 6, 2016 I'm thinking of messing w/ a Stock 2/3. I'm currently using a SP-01 Shadow. There are so many similarities between these 2 platforms, I'm wondering if the short cut chambers on the barrels is one of those things. Currently, I'm having to load my 147 FN coated to 1.085-09".

Beastly Posted July 6, 2016 Share Posted July 6, 2016 Yes...My 2 S2's and 1 Lim Pro ranged from 1.085 - 1.110" for 135 gr RN Bayou bullets. Link to comment Share on other sites More sharing options...
JusticeOfToren Posted July 6, 2016 Share Posted July 6, 2016 Not really. Before I switched form MP9 to tanfos, I heard the same thing. I even had a gunsmith ready to ream the chamber. However, it turned out no need. I did not even adjust anything on my 650. My two Stock 2s and one Limited Pro eat Bayou 147FP @ 1.135-1.140 OAL happily in thousands.

johnbu Posted July 6, 2016 Share Posted July 6, 2016 They sadly share that same condition. But they also feed flawlessly short. I was going to get mine done, but... ehhhh it works great now. Link to comment Share on other sites More sharing options...
haiedras Posted July 6, 2016 Share Posted July 6, 2016 Send to Bevin Grams... he'll ream it. I now load to 1.175" Did he ream your s2 or s3? The s2s have a hard chromed barrel that requires a carbide reamer, not your standard hardened steel reamer. Link to comment Share on other sites More sharing options...
haiedras Posted July 6, 2016 Share Posted July 6, 2016 Cool, I know bevin, just didn't know he had a reamer that would cut into the hard chrome. Good info to know. Link to comment Share on other sites More sharing options...
Yagi Posted July 6, 2016 Share Posted July 6, 2016 I heard new tanfo these days are short chambered. My s2's takes 1.165" oal easy but then again my tanfo's are from way back. Link to comment Share on other sites More sharing options...
Bamboo Posted July 7, 2016 Share Posted July 7, 2016 Yep, Beven is the man. My tanfo was a little short for the loads I wanted to run. He did my tanfo 9mm barrel for a great price and had it back in less than a week. Link to comment Share on other sites More sharing options...
Hylton703 Posted July 7, 2016 Share Posted July 7, 2016 Matt Cheely said he could ream my S2 barrel. Haven't sent it yet but I believe he said 1 day turnaround. Link to comment Share on other sites More sharing options...
MemphisMechanic Posted July 7, 2016 Share Posted July 7, 2016 The plunk test in your chamber? It depends GREATLY upon the profile of the bullet. An M&P of mine won't take a 135 gr RNL past 1.105" ... but eats 1.170" 124gr FMJs like candy. Does the stock 3 have a hardened barrel like the 2? It doesn't need to be hard chromed to be reamer-proof. The factory barrel in an XD-m and an M&P both laugh at a standard reamer as it is slowly dulled without making a scratch.

JeffD Posted July 8, 2016 Share Posted July 8, 2016 (edited) I bought a new Stock 3 from Ben Stoeger Pro Shop 3 weeks ago and am still using my minor load for my M&Ps. 147 flat point Bayou loaded to 1.135-1.140. Only 350 rounds so far but it eats them flawlessly. Maybe the tolerances of their barrels are like the tolerances of their internal parts. What do you expect, they're Italian made. Except more like an 80's Ferraris instead of a 488 GTB. Edited July 8, 2016 by JeffD Link to comment Share on other sites More sharing options...
GringoBandito Posted July 8, 2016 Share Posted July 8, 2016 I recently bought a stock 2 and ordered some 147 grain bbi and blue bullets only to find I could only load to 1.09 to fit in the barrel. I tried some 147 grain xtremes and can load to 1.130 and they pass the plunk test with ease. Link to comment Share on other sites More sharing options...

Have you plunk tested those, with a spin? Of course. More importantly, I have tested it by shooting 8k with zero load related malfunctions, including 2 major matches. I'd say all 3 of my tanfos like the 1.140 OAL of Bayou 147FP profile. YMMV. Link to comment Share on other sites More sharing options...
sporter Posted July 9, 2016 Share Posted July 9, 2016 I run Xtreme 124 round nose, out of my S3 @ 1.15. All will pass plunk and turn, no problem. Tried other brands of coated bullets and they would engage WAY too early, and I don't like loading short. Link to comment Share on other sites More sharing options...

cjdaniel78 Posted July 10, 2016 Share Posted July 10, 2016 Call Bevin Grams. Mine was short using Blue Bullets 124 round nose. He reamed it and it's been flawless. He mentioned some round nose profiles were a little fat and would engage early. Money well spent. Link to comment Share on other sites More sharing options...
MemphisMechanic Posted July 10, 2016 Share Posted July 10, 2016 Do the Lim / Lim Pro / Stock 3 barrels take a reamer smoothly? Apprently the Stock 2's hardened barrel needs special treatment... but will an ordinary manson reamer do the job on the rest of the Tanfo line?

cjdaniel78 Posted July 11, 2016 Share Posted July 11, 2016 Not sure what your answer is, but Gram's reamer makes it good and smooth. Link to comment Share on other sites More sharing options...
MemphisMechanic Posted July 11, 2016 Share Posted July 11, 2016 I'm asking if the reamer a local has - the one I used to throat the APEX match barrel in my M&P in about 4 minutes - would work. Link to comment Share on other sites More sharing options...
lesm Posted July 12, 2016 Share Posted July 12, 2016 I have successfully throated 4 Stock2's, 4 Limited's and several matches with a Manson throating reamer. The reamer would not work on a Xdm 5.25 nor a CZ P09. For the polygon barrels I used a Manson reamer with the pilot bushing sized for the polygon. For lands and grooves barrels Dave's standard throating reamer works fine. I don't know about your barrels. They may be harder. My newer S2's appeared to have a chrome lined bore but the throat and chamber did not look like they had chrome on them. Link to comment Share on other sites More sharing options...
