Broncman Posted May 11, 2018 Share Posted May 11, 2018 Well, I decided to popple. After building my first open pistol using a Brazos Thundrcomp SX2 Trubore, I was never thrilled with it. Always hear about shooting flat etc and after loading to nearly 180 PF using HS6, AA7 and 3N38 ,then up to 175 with auto comp, I never got it what I thought was good enough. Tried different springs and settled on HS6 and an 8 lb spring. I just could not slow down on the longer shots and would get miss or a wide shot. I know practice plays a lot into this, but I want to shoot fast !! I added 2 popple holes and it honestly made a difference! Was worried about accuracy loss, but there was none I could tell. Went to the local indoor range with some different loads and ended up at 7.8 grains HS6. When it quits raining I will Chrono. Should have poppled sooner.

Bwilmot Posted May 11, 2018 Share Posted May 11, 2018 (edited) I just added 2 5/32 holes in my sps vista short. I should have done this long ago tooo. 25-30% less dot movement:) I’m running 9.9 aa7 under 115 at 170ish PF. I’m still working on loads but this one feels very good.

Broncman Posted May 12, 2018 Author Share Posted May 12, 2018 I did two 3/16 holes. Was really skeptical, now I am excited! Link to comment Share on other sites More sharing options...
aandabooks Posted May 12, 2018 Share Posted May 12, 2018 I've been thinking about adding up to 3 holes. I've been on the fence. Link to comment Share on other sites More sharing options...
kujo929 Posted May 12, 2018 Share Posted May 12, 2018 Aandabooks just poppled my second gun. I was on the fence as well and had it done to my backup gun first. Huge improvement. He just did the second one now. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
echotango Posted May 12, 2018 Share Posted May 12, 2018 3x 1/8" holes on all mine. Link to comment Share on other sites More sharing options...
Broncman Posted May 12, 2018 Author Share Posted May 12, 2018 Nice brace of pistols! I did mine with the first hole about 13/16 from the muzzle opening. I wanted the Jets to have as much time to vent as I could. Hopefully I can Chrono it this weekend. Link to comment Share on other sites More sharing options...

echotango Posted May 12, 2018 Share Posted May 12, 2018 Funny. Actually the 2 on the right will be for sale shortly. Just finished the other 2. Link to comment Share on other sites More sharing options...

zzt Posted May 12, 2018 Share Posted May 12, 2018 I have wo 3/16" poppels in my Open gun. My upright mount has a blast shield, but the lens of the C-More does get a little dirty after two matches. It is quite easy to clean, and does not damage the lens. My next Open gun will have poppels in the comp, probably in a V2 arrangement. Link to comment Share on other sites More sharing options...

When I used to use liquid oil for lubrication, I had to clean my C-More lens after each stage Since I switched to Brian's Slide-Glide, I NEVER get my lens dirty, anymore Link to comment Share on other sites More sharing options...
BoyGlock Posted May 12, 2018 Share Posted May 12, 2018 Gases out of my popple holes never touch my cmore lens. The hole nearest to the lens is angled a bit forward emitting gas away from the lens that serves as a wall to the remaining gases forward of it. Its a schuemann.

Broncman Posted May 13, 2018 Author Share Posted May 13, 2018 Back from the range and Chrono. Took 7.9 great HS6 to go 1360 with a 124 blue Bullet. 1355 lowest and 1367 highest out of 10 shots. I'LL keep it! Link to comment Share on other sites More sharing options...
Jeremyc_1999 Posted May 14, 2018 Share Posted May 14, 2018 Who are you having put your popple holes in? I'm thinking that this fall I will put some popples in my gun Link to comment Share on other sites More sharing options...
Broncman Posted May 14, 2018 Author Share Posted May 14, 2018 I did it myself in my mill. Not hard to do, could be done in a drill press. Link to comment Share on other sites More sharing options...

If the ports are slightly angled forward there is little to no lens residue. Below is a clip from a short test video I made. You will note the port on the c-more side is angled forward more than the front port which then blocks the gases from moving towards the sight. I run an 90deg no shield c- more and am able to stay pretty clear. Link to comment Share on other sites More sharing options...
msg73 Posted June 10, 2018 Share Posted June 10, 2018 I’ve been on the fence on adding popple holes for a while now. Can you guys provide some additional details on your personal experiences (e.g. how much reduced dot movement, does it hit harder now, any change in splits, how much more powder needed for same pf, etc)? I’m currently using 8.7gr hs6 with PD 115 jhp at 1.165 to get 170pf, so my barrel seems fast enough to take the holes without having to overfill the case with powder.

I’m currently using 8.7gr hs6 with PD 115 jhp at 1.165 to get 170pf, so my barrel seems fast enough to take the holes without having to overfill the case with powder. Mine was fast also. Making Pf lower than most other charges posted on here. Adding 3 popples only reduced my FPS by 40. In my book total improvement. Yes more violent in hand in my opinion but what I would describe as snappier. Less height in dot travel. I still ended up going away from 125’s to 115’s but I think the popple holes were at least that same amount of difference if not more. In terms of shooting it has basically taken a 10-12yd 8” steel plate from being, shot,watch dot return, shot - to now being 2 shots as fast as I can pull trigger so long as grip and the rest of it is there. Smashing Splits on A’s inside of 10 requires little thought at all now compared to before popples it would often become A,C if I pushed the speed much. All my experience is on Tanfo gums but don’t see how it wouldn’t be similar for any of them. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Knguyen1904 Posted July 3, 2018 Share Posted July 3, 2018 Lots of good info on here. I’m looking to get mine done here in the near future. I currently run 8.5 gn hs6 with a PD 115jhp our of a 5” infinity ultimatch barrel . What bullet weights are you guys running with popples Link to comment Share on other sites More sharing options...
aandabooks Posted July 3, 2018 Share Posted July 3, 2018 I was running 124 PDs with CFE until I tried a batch of 115gr with HS-6 after I put in 3 popple holes. Huge difference with the lighter bullet and more powder. Dot doesn't leave a 6" piece of steel at 15 yards. Link to comment Share on other sites More sharing options...

I shoot blue coated though. Same load you are using with the PD. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
