Dirty_J Posted April 10, 2020 Share Posted April 10, 2020 What’s the go-to kit? Im going to grab the CZC 140 and 170 base pads. Should I get their spring/follower kit? Or get the Grams? Link to comment Share on other sites More sharing options...
aandabooks Posted April 10, 2020 Share Posted April 10, 2020 Grams but you will also likely need to tune your mags. I tried to get mine to run with springs and followers from CZC and then switched to Grams. Got better and played with load lengths. I finally tuned my mags and they have been flawless ever since.

What’s the part number for the grams springs and followers for the 170mm mag? What’s your load length? I can’t get the CZC spring and follower to work in my big stick with 1.160-1.165” OAL. Thanks.

aandabooks Posted April 10, 2020 Share Posted April 10, 2020 They are at Shooter's Connection. 13 coil for the 170mm mag. I'm at 1.165" with Everglades 124gr bullets. Even with the Grams the mags did not run 100% until I tuned the mags. They had to be squeezed down like .060" from where they were. Not hard to do with a vice but the feedlips will need pliers to get them right. Link to comment Share on other sites More sharing options...

George16 Posted April 10, 2020 Share Posted April 10, 2020 (edited) Thank you. I’ll order a couple tonight. I’m loading 124 Gr JHP from PD with 10.2 Gr of AA7. I’ll make a jig out of wood so it won’t get damaged when I squeeze it down in my vise. What measurement did you get on the feed lips after you were done tuning the mag? Edit- Shooter’s Connection is out of stock on the 13 coil. Edited April 10, 2020 by George16 Link to comment Share on other sites More sharing options...
aandabooks Posted April 10, 2020 Share Posted April 10, 2020 For the control rib: 0.735” just above the mag catch hole Feed lips: 0.365” in the rear, 0.375” in the front Link to comment Share on other sites More sharing options...
aandabooks Posted April 10, 2020 Share Posted April 10, 2020 Just noticed that Shooters Connection is out of stock on the 13 coil. Here is a link for Grams where they have the 13 coil kit. It is the FKCL-13 you'll want. http://gramsengineering.com/products/?p=productsList&iCategory=16 Link to comment Share on other sites More sharing options...
George16 Posted April 10, 2020 Share Posted April 10, 2020 Just ordered a couple. Their order form is one of a kind. There are no payment options so I’ll just have to wait for them to call me like it says. Thanks again. Link to comment Share on other sites More sharing options...

I emailed them a couple of days ago to inquire about tuning my big stick. No reply as of yet. Hopefully they’re working and don’t have the ‘Rona.

You’ll see the page where it explains why they don’t have payment options and wait for someone to call you to make sure you ordered the correct product.

Timido Posted April 14, 2020 Share Posted April 14, 2020 I tried ording grams springs through their web site. Never heard anything Back. Buy them from Shooters. If they don't have the 13 coil with the follower you can buy a 11 coil with follower one and an extra 13 coil spring. Same follower Link to comment Share on other sites More sharing options...

I even called their number but it just keeps on ringing. Probably nobody is at the office due to the Coronavirus. Thanks for the info. Didn’t realize that any grams 13 coil spring will work as long as I have the TSO/Czechmate specific follower. The standalone 13 coil springs are also out of stock so I ordered a couple of the STI/SV kiss and will just swap the followers.

regor Posted April 14, 2020 Share Posted April 14, 2020 For what it's worth I have found that using the Grams/CZC followers in the big sticks doesn't actually get me extra rounds, I can still fit 29 in either way, it's just a little easier to seat with the Grams followers. The OEM one seems to give me more reliable feeding in my experience, so I have stuck with those. I don't reload to big sticks, so the extra slack doesn't matter much to me. For the 140s the grams followers let me get 24 vs 23 rounds with the OEMs, but it's not a reloadable 24; the 23 rounds with OEM follower are plenty reloadable. If this was for a carry optics gun then having 24+1 as an option is a no-brainer, but why start 24+1 when you can start with a big stick...

Did you put the big stick in a vice and just squeeze it down .60” cause I’m having the same issue with mine and have tried for month to get in contact with Bevin Gram Link to comment Share on other sites More sharing options...

For the control rib: 0.735” just above the mag catch hole Feed lips: 0.365” in the rear, 0.375” in the front Those are the numbers that I tuned my mags to. You'll need a caliper, something to squeeze the mag body with and a pair of feed lip pliers to tune the feed lips. All my mags were drop free but most measured up around .790" when I got started. I made some jaws for my vice but this could be done with some vice grips with the narrow jaws. Take the mags apart and squeeze them down to the .735" measurement. Make sure they still fit your gun and drop free. If not you'll need to squeeze them front to back. Next to do is check the feed lips. They will likely be smaller so you'll need to open them up. Tools like these are what you'll need to get them tuned: https://www.amazon.com/gp/product/B0006MTTPY/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 https://www.amazon.com/Armor-AUTOMATIC-Clamp-Plier-7CC/dp/B07PGJCR3R/ref=sr_1_18?dchild=1&keywords=vice+grip+clamping+pliers&qid=1587734461&s=hi&sr=1-18 Link to comment Share on other sites More sharing options...

I assume a lot of trial and error. Let me ask, what do you use the Locking C-Clamp for? I see the Chain Pliers is used to open up the feed lips. It does seem odd... I'm just now buying a bigger mag when ammo is in short supply, lol. Edited June 25, 2020 by robert.a.brewer. Link to comment Share on other sites More sharing options...
George16 Posted June 26, 2020 Share Posted June 26, 2020 (edited) You use the locking clamp to pinch the rib on the mag. I used a 3/8 dowel placed on the rib right above the mag catch hole to pinch my mags. I use the info @Aandaboks posted above and it worked well. I can now load 29 rounds on my big stick and 23 rounds on my 140 reliably. I used CZC extension, springs and followers on mine. Good luck getting a hold of Grams. I called and emailed to no avail.

bludog Posted February 2, 2022 Share Posted February 2, 2022 I tried calling Gram Engineering(and leaving a message--twice) and emailing on the gram order form over the last week with no response. Vacation ? Covid ? Busy ? Any clues ? Link to comment Share on other sites More sharing options...
NorthwestGuy Posted February 2, 2022 Share Posted February 2, 2022 I had the same issues. Put my mags in a box with a note as to what I wanted with my contact information. He called me for payment and they came back done two days later. Whatever works...the man is crazy busy. Link to comment Share on other sites More sharing options...
bludog Posted February 9, 2022 Share Posted February 9, 2022 May I ask what the approximate cost was for the mag tune ? Did you send both 140's and 170's ? Were you having reliability issues feeding prior to the tune ? and now ? thanks in advance for your help Link to comment Share on other sites More sharing options...
NorthwestGuy Posted February 13, 2022 Share Posted February 13, 2022 I had him replace followers and springs in 2- 140's and 1- 170 as well as tune all. The delivered price was about $170. Yes, I was constantly having rounds nose-dive. I have not had a single issue since he worked on the mags. 100% recommend. Link to comment Share on other sites More sharing options...
