I recently purchased an Infinity Sight Tracker (won't fire factory loads) and I am incrementally trying to get to the right overall length for my rounds. I started off with what the Speer manual had stated 1.125 which didn't work. I've worked my way up to 1.214 and there has been improvement but I'm still getting a few FTF's. Some SVI owners have said that I should be taking it up to a longer length and that differs with who you talk to.

I noticed that the 10mm COL is 1.250 and the only difference is tha actual case length. Can anyone explain to me the disparity in the OAL between the 10mm and the 40SW and I would appreciate feedback on what fellow Infinity 40SW shooters are loading their rounds to.

Finally, I will be heading out of state for training and matches (requires flying) and I would prefer not to make thousands/hundreds of rounds and then ship them to where I'm going (it's a hassle and it gets expensive). Again, I would appreciate some feedback on why the model gun I bought doesn't run with factory ammo.

Thanks,

Bill Caldwell

Duffy,
The length a 40 can be loaded to depends on how much free bore the chamber has. I chamber with more freebore than most......180gr at 1.250.
To some shooters......the loads look "funny".....Short case, lots of bullet stickin' out, all things bein' equal, more free bore equals less presure....higher velocities and less recoil.
Thanks,
Bill Caldwell

What bullet, what powder load?

I had an STI Edge that I ran Montana Gold JHP's through at 1.22 with VVN320 powder at I believe 5.1 grains,,,,,it made major and was super reliable.

Oh,,,,I ran the ammo through a crimp die on the final station as well.

All was good in STI world with that load,,,,,just ran and ran.

Number 6

I load my .40 S&W cartridges to 1.230 -.250. I currently use 180 grain bullets and have gone as light as 170. This length worked in my P-16 and now works in my Sight Tracker.

Talkin' to a friend yesterday. He says, "I Have to taper crimp Long Loaded 40 loads at .420" for My STI to be reliable."

Thanks,

Excuse me but a +2000$ gun that wont shoot factory ammo ? I have long and shortloaded for various reasons but tend to set up my guns to run on somekinda factory commonly available load then adjust my reloads accordingly. Although I guess it is common for .40 S&W's to need longer than normal loads in 1911's I find it odd Para ordnance could figure it out for 499.99 but people feel like it's ok for a $2000 semi custom to not run on standard big three ammo. Send it back tell STI to fix their gun maybe if enough people do that there QC will come back to what it used to be

Unfortunately, folks, feeding reliability does not lie only in cartridge OAL. It is in the magazine, specifically the feedlip dimensions. Take a look here -

http://www.brianenos.com/forums/inde...agazine+tuning

Brian knows more about tuning SV mags than about anyone.

I also run a SV and I load my own ammo. Once I had my magazines tuned correctly, I've never had an issue that wasn't my fault.

And, I've never given a thoguht to factory ammo? Why? Because the ammo I load on my machine is (1) more accurate than factory ammo (2) shoots softer than factory ammo and (3) is far, far less expensive than factory ammo.

If you don't like the fact that your custom gun doesn't run on factory ammo :roll: , call SV and speak with Brandon or Sandy.

Bill Caldwell

Duffy1 ask about OAL. Most answers pertained to OAL

BigDave....With all due respect Sir,....Some that post on this forum know as much about mags as Brian Enos or anybody else walkin' or talkin'. The easiest and the least costly way to learn what a correctly set up mag is? Buy one complete from GRAMS. The STI tubes I bought from Brownells, along with the springs, follower,and basepad worked. Haven't had a problem I could say was mag caused. Is the one from Grams better?......I don't know. How can You tell when they all work? After a while I replaced the internal parts with GRAMS, Not that they were causein' problems....I like the GRAMS base better.

Thanks,
Wild Bill

Truly, you have a dizzying intellect. 8)

Yeah, Bill, I'm sure you and a host of others here and elsewhere know a lot about mags. But I'm pretty sure that few if any of them (1) worked for SV, let alone (2) designed designed a follower for those magazines - like Brian Enos did. And, I'm not exactly sure how my previous post somehow did any injustice to anyone I didn't mention, but I'm sure you'll be here in a quick second to tell me about it.

Personally, I default to Brian then Bevin then Bob Londrigan when it comes to SV magazine tuning. Properly dimensioned and polished feedlips, good springs (ISMI or Grams), good followers (SV or Grams) and proper OAL (I run mine at 1.190" for 40 S&W) solved my FTF issues in my SV.

Duffy1 - I hope this advice was useful.

DIZZYING INTELLECT????
When I signed up over here I didn't see a blank space on My application to enter My I.Q.

Little Davey .....There's a bunch of Us on Pistolsmith that can equal or surpass any thing Brian Enos or You have designed. Dane Burns designed and markets the best HAMMER, SEAR,and DISCONNECTOR there is. BUT ....the deal is....What can You Do? I can't run on what Brian Enos can do , or what Dane Burns can do. You can't either. I survive on what Wild Bill Caldwell can do and that's just the way the world is.

Little David....What's DIZZY is the way some of You people on Mako Mazo Kneel at Brian's feet and worship at His alter of zen.

Thank's,
Bill Caldwell

Wild Bill...Just gonna sit back and watch this show...for a while.

BigDave

And thus I clothe my naked villiany
with old odd ends stolen forth from holy writ
and seem a saint when most I play the devil.

Oh, and PM inbound...

Now, back the to topic...

For the last time. Duffy1 asked questions about cartridge OAL in regards to a new SV because of FTF problems he had with his gun. I read the posts discussing OAL and then I offer, in addition to the other germaine posts, another suggestion that the Duffy1 might consider on his quest for 100% feeding. In doing so, somehow, I offened you, Bill, because I mention advice from someone you don't obviously care for.

Obviously I didn't know the depth of the mistake I was making.

Then, reluctantly in response, I add that the person referenced in my original post worked for the manufacturer of Duffy1's gun, shot them competitively for years and designed a magazine follower for such a gun made by SV. This is the same advice, in addition to adjusting OAL, that enabled me to feed my SV 40 S&W 100% reliably. What an idiot I am for posting it. I apologize.

If I have offended anyone by failing to mention John Moses Browning, Jim Clark Sr., Jim Clark Jr., Sandy Strayer, Chip McComick, Dane Burns, Bill Wilson, Virgil Tripp, Bob Londrigan, Bevin Grams, Benny Hill, Alex Hamilton, Rusty Kidd, Tony Kidd, George Smith, George Huning, Matt McLearn, Joel Peters, Teddy Yost, anyone else in the APG, anyone else who's handled a 1911 (and their variants), anyone who's seen a 1911 in print ads, TV or the movies (whether they knew it or not) - I apologize.

Now THAT'S funny!

BIGDAVE,
That's got to be the LONGEST, MOST PITIFUL WHINE I've ever heard. One of those "I soaked My pillow all the way thru with tears last nite", WHINES. You havein' a zen moment, BIG DAVE?

It's HELL out here in the west, ain't it Big Dave?(West Monroe Louisiana, that is) Over here You can't fire off a smart A$$ shot....Then run to Your MOD buddy and get the thread locked to stop any replies.

Sendin' You a P M when I get time.

Thanks,
Bill Caldwell

BigDave

Will someone please tell me where the lever is that drops a 10 ton weight on my head like in the old Looney Tunes cartoons? Where?!?!?!

Bill -

I didn't go running to Mr. Berryhill or any other moderator on this forum. If you have issues with his post, take those up with him directly. They were not solicited by me in any way.

Whining? If that's how you wish to look at it, fine - obviously I can't stop you. You have issues with my reference to Brian Enos, his advice, his web forum and his spiritual practices - all of which have zero to do with me so please take those up with him.

If the quotes that I used to start my previous two posts got under your skin (and clearly they did), I can't say it wasn't unintentional. You, unknowningly, found me in a bit of a mood and I love being a smarta$$. Was that the proper thing to do when it is so easy for us to hide behind monitors and keyboards? Probably not. But, here's a deal - I'll stop making wise cracks if you stick to the topic at hand - getting Duffy1's SV to feed 100%.
