robot Posted June 7, 2011 Share Posted June 7, 2011 SRSLY! There is NO way I can get even close to 29 rounds of 38 Super Comp in my magtubes. I'm using a SV 170mm magtube + grams spring+follower 13 coil, and bolens 3mm basepad. I just about make gauge and can only fit 28. I can even squeeze in the 29th round. How do you guys ever get to 30? or even worse 31? sounds like hogwash to me. ok the last statement was just to stir up the post, but in all honesty, can you guys share what "ingredients" you're using for your 170mm magazines that allow you to fit 30 rounds of 38 Super Comp? and I'm not looking to actually give up reliability for one more round but I'm just really curious to find out how you guys do it. thanks!

rupture Posted June 7, 2011 Share Posted June 7, 2011 send it to Adrian @ mag blueprinting ,he will get 30 out of it Link to comment Share on other sites More sharing options...
remoandiris Posted June 7, 2011 Share Posted June 7, 2011 I shoot 9 Major. I have 2 SV big sticks. Both have Bolen guts and 3mm base pads. Both were tuned by the same guy. One gets 29, the other 30. How do you explain that? I call it manufacturing differences. BTW, I can NOT load to either one when they're full. A guy I sometimes shoot with can fit 30 AND load to his big sticks. I don't know how to explain that, either. SRSLY! There is NO way I can get even close to 29 rounds of 38 Super Comp in my magtubes.

Pezco Posted June 7, 2011 Share Posted June 7, 2011 I have 2 stock SV big sticks with standard SV springs, followers and 3 mm base pads and get 29 rounds reloadable. I just purchased the new aluminum followers from SV and can squeeze 30 into one of the mags and only 29 in the other. It is a rare occasion I will load 29+1.

Foxbat Posted June 7, 2011 Share Posted June 7, 2011 I feel this is just a silly game, but I can be as silly as the next guy. No practical difference in one or two extra rounds, but I still like it when I can put in 30. Got a call from my smith the other day, he said he tuned one of my SVI mags to hold 30-31. Frankly, I did not even ask him, he volunteered. No way of knowing what he did - but the magazine has Bolen guts and 3mm pad. A small variation in tube geometry can have pronounced effect. With different new tubes you can get either 28 or 29 with the same guts. Not really surprising when you measure the tubes - they are not exactly all the same. One important element of tuning is extending the side groves down. Otherwise the tube will take the rounds, but will be susceptible to salt shaking. I have seen different ways of doing that, and it will be interesting to see how my smith does it. BTW - it is easier to do more rounds with 38SC than 9mm, due to diameter differences. In some mags I can put one extra 38SC round. Link to comment Share on other sites More sharing options...
Torogi Posted June 7, 2011 Share Posted June 7, 2011 Stock SVI 170mm tube, bolen spring and follower, Dawson +1 basepad, 29 reloadable. 9mm. Dawson SNL, 30 reloadable, needs trimming on the feedlips to gauge. I personally just load 29 or 28. and there is a trick for untuned tubes that can take higher rounds, load SLOWLY. or else it can go under and be a shaker. I have spoken to Adrian of Magblueprint, he can definitely tune it to take higher rounds, but do not recommend maxing it out to 31, IF it can take 31. I prefer actually to do a magchange for a 31 round count stage. I spent about 2 weeks, tons of questions to other members, $50+ buying parts for an untuned mag to take 30.. BUT there is nothing much more cooler than a bad ass sub-second mag reload but still, im working on the sub-second thing Link to comment Share on other sites More sharing options...
OpenDot Posted June 7, 2011 Share Posted June 7, 2011 MY SVI Bigstick with Bolen Spring, Follower and Basepad holds 29 9major. I can cram 30 in it only to find it binds up and turns into a salt shaker and have to dissasemble to get the fallen round in the bottom. So I load it 29 +1 Link to comment Share on other sites More sharing options...
shooterbenedetto Posted June 7, 2011 Share Posted June 7, 2011 Been there done that, becareful loading so much as it will crack your grip. 28+1 is good enough for me, as there is always a reload place in a stage somewhere. Reliability goes a long way! Link to comment Share on other sites More sharing options...
Foxbat Posted June 7, 2011 Share Posted June 7, 2011 Been there done that, becareful loading so much as it will crack your grip. I never force the magazine into the grip for this reason - if it requires more than a gentle push, that is bad idea. I am also not sure why one would need something like 29-29 ***reloadable*** - I usually reload with no more than 26, to avoid any possible latching problems.

Aircooled6racer Posted June 7, 2011 Share Posted June 7, 2011 Hello: I use the SVI tubes,Bolen follower/spring and a Grams 4mm base pad. They are a very reloadable 29 rounds and hold 30 rounds. These also fit the gauge. This is for 9mm and hold a reloadable 30 rounds of 38SC. At 30 rounds of 9mm it is just a slight "snick" to seat the mag so it will not break the grip. Make sure your mags fit the gauge since I have seen some so called magic 31 round mags that do not fit the gauge Hope this helps.

Chris Keen Posted June 7, 2011 Share Posted June 7, 2011 I have 1 SV 170 tube, and 1 170 STI tube that I can get 29 rounds in each. Bolen 4mm basepads, and Grams springs & followers. Both fit the gauge with no problem. Link to comment Share on other sites More sharing options...
remoandiris Posted June 7, 2011 Share Posted June 7, 2011 I am also not sure why one would need something like 29-29 ***reloadable*** - I doubt anyone NEEDS 29 reloadable. But no one NEEDS to catch a round in the air after ULSC (another thread), nor do they NEED a $5K Open gun. But if you can do it, it isn't against the rules and is safe, why not?

A few weeks ago at a local match, there were 2 people in the same squad who both had detonations from racking the slide back hard enough to get the round up so they could catch it. One sliced his hand up pretty good. Link to comment Share on other sites More sharing options...

You can also have ten magazines with 300 rounds on your belt... Me, I would rather reload with a 26 round magazine, plus have one spare on my belt.

Aircooled6racer Posted June 8, 2011 Share Posted June 8, 2011 Hello: I use Bolen guts and a Grams 4mm base pad on the SVI mag tubes. On the STI tubes I use Grams guts and Grams 4mm base pad. I prefer the Grams base pads since I can remove them easier than the Bolen. Hope this helps. Thanks, Eric Link to comment Share on other sites More sharing options...
Chris Keen Posted June 8, 2011 Share Posted June 8, 2011 Well: I will never use Bolen guts in anything but an SV mag. I have never had any luck with them in a STI tube. But with that said I am now more a fan of the Grams guts, simply for the 100% reliability I get out of them. I prefer the Bolen base pads since I can remove them easier than the Grams lol, plus Bolens never crack, since they are aluminum. Link to comment Share on other sites More sharing options...

818-DVC Posted June 8, 2011 Share Posted June 8, 2011 Sv tube, Bolen spring/follower, 1+1 SNL. Base pad with a little recessed off the inside of the pad holds 30 reloadable. with Rescomp tubes, Bolen 3mm pads held 31.. no salt shaker effect once, but the springs wear quick.

robot Posted June 8, 2011 Author Share Posted June 8, 2011 ahh ok! looks like all I needed to do was to compress the spring a little more. Perhaps they're new. Now I can get 29 in both my 170mm SV tubes with Grams spring+follower and Bolen 3mm basepads. Feeds fine cycling it by hand. Haven't brought it to the range to try live fire. Will do that this Friday. 29 in SV 170mm + Grams guts + Bolens Basepad 28 in SPS 170mm + STI guts + Bolens 4mm Basepad 22 in STI 140mm + STI guts + Bolens 7mm basepad Won't go to 30 unless I risk changing the structural integrity of the mag tube or send it to a mag specialist and pay $165. Definitely not worth it for one extra round. Link to comment Share on other sites More sharing options...

Aircooled6racer Posted June 9, 2011 Share Posted June 9, 2011 Hello: Bolen's may be aluminum but they do bend when they land on a rock on the bottom. Then try to remove them. $165 to tune a mag? Thanks,Eric Link to comment Share on other sites More sharing options...
Tom Freeman Posted June 9, 2011 Share Posted June 9, 2011 I roll size all my brass and can get 30 rounds in a SV or STI tube with grams guts and an old 2.5 or 3mm pad. Link to comment Share on other sites More sharing options...
