40S&W Posted May 26, 2013 Share Posted May 26, 2013 Using Dawson tuned 140 mm 38SC mags with the following. STI Mag ISMI 11 coil spring Dawson +1 basepad Dawson 38 Super Competition follower Getting 21 rounds. If I changed to Grams Guts would I get anymore rounds with reliable feeding?

calvinc78 Posted May 26, 2013 Share Posted May 26, 2013 I shoot 9major and I get 23 with Dawson +1pads and Gram guts... I know people say you can get a extra round with SC.... Link to comment Share on other sites More sharing options...
al503 Posted May 26, 2013 Share Posted May 26, 2013 I'd be surprised if you didn't get another round with the grams guts. However, the only issue with getting more than 21 rounds in an STI tube is that the ribs don't go down far enough on one side of the tube. You can get a round stuck side by side on the follower at the bottom of the mag. No such issue with the 140mm SV tube. Link to comment Share on other sites More sharing options...
Albertl35 Posted May 26, 2013 Share Posted May 26, 2013 I can get 23 reloadable on an STI mag with Bolen/Taran Butler follower, spring and basepad (7mm) and 24 reloadable with a SV tube with both 9mm or 38sc. Link to comment Share on other sites More sharing options...
CocoBolo Posted May 26, 2013 Share Posted May 26, 2013 Spend your money on a big stick if you need more capacity. I get 24 in my 140's with a Dawson +2 pad, the only reason I have them on a 140 is because the are not legal on a 170. The standard 140 sti mag with the little plastic flat base pad and sti follower holds 21, so what did the +1 SNL do for you? I can get 31 in one of my SVI big sticks if I cram it in there, then barney up one, and slam it home like hoss cartwright stomping on a bed bug, but every time I do that I miss a piece of steel and wind up reloading anyway, I need one that holds 33.

40S&W Posted May 27, 2013 Author Share Posted May 27, 2013 The Dawson +1 didn't do anything for me, same round count as a standard STI basepad. That's why the question. I have Grams guts in my Limited 10 & 9mm mags, no capacity issues. I have 170mm 29+1 Superior mag for 9mm & a STI mag 30+1 for 38SC. Both the 170mm mags have Grams guts. Guess I will try Grams guts, and see if I can reliably pick up one or two rounds. Thanks for your comments. Link to comment Share on other sites More sharing options...
Foxbat Posted May 27, 2013 Share Posted May 27, 2013 I don't even know... something like 24-25, but I simply treat them as 20 round mags, if I need anything bigger I get the 170. I like Grams 11mm pads with Bolen guts. Link to comment Share on other sites More sharing options...
Ace38super Posted May 27, 2013 Share Posted May 27, 2013 I like to keep it simple. Use a 140 mag with 20 rounds. Grams spring and follower, Dawson + 1 base pad. I started with grams base pads but I think the Dawson is easier to remove for cleaning. For any stage that requires more than 15 rounds I use a big stick. That way I never worry about round count or a 140 mag that yaks due to more than 20 rounds stuffed in it. I have ffriends that use only big sticks and there's an argument for that too.

sauza45 Posted May 27, 2013 Share Posted May 27, 2013 I use the Brazos tuned mages. They have grams guts and dawson snl pads. I get 23 reloadable all day long. Link to comment Share on other sites More sharing options...
Hammar Posted May 27, 2013 Share Posted May 27, 2013 I use the Brazos tuned mages. They have grams guts and dawson snl pads. I get 23 reloadable all day long. I use the same and only get 21. Weird. Link to comment Share on other sites More sharing options...
EkuJustice Posted May 28, 2013 Share Posted May 28, 2013 Untuned sti mag body with hardy spacer grams spring and follower and snl base pad for 23 reload able. My big stick is untuned with grams guts and Dawson non snl for 28 I can reload to. It would do 29 with a snl but the non snl gives me more wiggle room in the gauge Link to comment Share on other sites More sharing options...
MoNsTeR Posted May 28, 2013 Share Posted May 28, 2013 If it's for Open, just use bigger basepads. I run Dawson +3's or Grams 11mm's on my 140's and get an easily reloadable 24 (25 really but I stick to 24 to go easy on the springs). Arredondo +3's should give the same result, and Bolen/Taran 7mm pads should as well (or close). Link to comment Share on other sites More sharing options...
OpenDot Posted May 28, 2013 Share Posted May 28, 2013 It's OPEN... use a belt feeder LOL my 140's hold 22 and i'm good with that, stage has more than 31 rounds i'm reloading anyways and use 2 - 140's. Link to comment Share on other sites More sharing options...
9X23Guy Posted June 2, 2013 Share Posted June 2, 2013 24 rounds, 140mm STI tube, grams guts and Arrendondo base pad. It is NOT 140mm and only legal for Open but I have a couple set up that way. Link to comment Share on other sites More sharing options...
