gunnit Posted November 6, 2015 Share Posted November 6, 2015 I'm with open1215, 12+ grains ? R.Elliot what was the load in that gun, and what recoil spring were you running with it ? That was cool to watch. I will go out on a limb and say it did make major. Link to comment Share on other sites More sharing options...
Open1215 Posted November 6, 2015 Share Posted November 6, 2015 Well my svi with 4 port hybrid and 3 port comp uses 11g N105 under a 115g but still, idt I would go over that. 11g flattens primers like 10.5g 3n38. Link to comment Share on other sites More sharing options...
gunnit Posted November 6, 2015 Share Posted November 6, 2015 I run 10.5 grains of 3n38 behind a 124 grn RN out of my Tanfo 38 V12, with no flat primes, but it doesn't do that. Link to comment Share on other sites More sharing options...
Open1215 Posted November 6, 2015 Share Posted November 6, 2015 Well out a v12 10.5 is reasonable. What primers and oal are you using? Link to comment Share on other sites More sharing options...
gunnit Posted November 6, 2015 Share Posted November 6, 2015 (edited) Primers are Federal or Winchester Small Rifle , 1.250 OAL. I've never seen that amount of sparks exiting the nose, I've watched it a half a dozen times and it doesn't get old, lol. It really looks pretty flat shooting. But the person running it would know exactly what is truly happening and if the dot was leaving the glass.

Open1215 Posted November 6, 2015 Share Posted November 6, 2015 Hmm. Got ya. I run CCI and they do flatten but o well. They don't look any worse then in 9. Link to comment Share on other sites More sharing options...
kneelingatlas Posted November 6, 2015 Share Posted November 6, 2015 If you want to really flatten out your load, switch the bullet to 95gr and increase the charge by a grain. I shot 10gr of SP2 under a 100gr pill through my 9mm V12 and it was pretty awesome Link to comment Share on other sites More sharing options...
gunnit Posted November 6, 2015 Share Posted November 6, 2015 Are you running Small Pistol Primers with the 11 grn ? Link to comment Share on other sites More sharing options...

Garmil Posted November 6, 2015 Share Posted November 6, 2015 I'm working on a 100 grain AA#7 load right now. Should make minor at 9.5-10 grains. Link to comment Share on other sites More sharing options...
gunnit Posted November 6, 2015 Share Posted November 6, 2015 I've never gone that high with any powder, but I will be careful if I decide to try it out. Thanks for the info. Link to comment Share on other sites More sharing options...
BeerBaron Posted November 6, 2015 Share Posted November 6, 2015 I like flat but as I learn I tend to agree that flat is it quite as important as consistent. No one is consistently making shots faster than a 10 or 12 split. Most of us on close open stuff are sub 15 but further/harder targets are 20+ splits. The gun can cycle in what .03? Let's say even 0.06. As long as the dot comes back to where it was when you broke the prior shot in less than say 0.09 you have plenty time to reel of those fast second shots. Having said all that I do prefe a flatter but harder recoiling gun over a softer recoiling gun with more flip. The little v12s with a good load are pretty flat and point nicely. They just constantly are trying to destroy themselves! Link to comment Share on other sites More sharing options...
BeerBaron Posted November 6, 2015 Share Posted November 6, 2015 Lol now we are getting near 9x25 loads. 90 grain pill going 2000fps! Flat? Yes! Hearing damage for your whole squad as a bonus! Link to comment Share on other sites More sharing options...
gunnit Posted November 6, 2015 Share Posted November 6, 2015 BeerBaron agreed , and the V12 is not a quiet gun to begin with, especially indoors. Sometimes painful. That's why seeing that gun spit out 12 grains was interesting. Link to comment Share on other sites More sharing options...
Open1215 Posted November 6, 2015 Share Posted November 6, 2015 I'm still debating going from 1/8th in to 3/16th in holes in my trubore based gun. I have a gaspedal but with my weak hand being so damaged the gun really has to do most of the work. (If this is a double tap I'm sorry. I thought I posted it here but now I don't see it) Link to comment Share on other sites More sharing options...
idHawk Posted November 6, 2015 Share Posted November 6, 2015 The beginning of flat Larry? Are you saying you shoot an Open gun where the dot doesn't leave the glass? If so I'd love to see pictures/videos. Atlas, I have owned 5 Open Guns built on the STI 2011 platform. With 4 of them I was able to get to the point where the dot did not leave the glass. As for the 5th gun.... well, that one hasn't been fired yet. Just got it this week and I am more than confident I will be able to achieve the same with this one.

BeerBaron Posted November 6, 2015 Share Posted November 6, 2015 I have another story about a guy shooting 90 or 100gn pills at 2000fps in a 9x25. He shot a stage and a popper was still standing. Asked for cal and it went down with the 120pf cal ammo. Went to pick it up and found he'd drilled a hole straight through it without making it fall! I didn't see this with my own eyes so it may be a tall story but I can believe it particularly if it's a forward faking popper set heavy. Link to comment Share on other sites More sharing options...

Gooldylocks Posted November 6, 2015 Share Posted November 6, 2015 And another one also from shred2dotnet https://m.youtube.com/watch?v=mdiE3NzMjg0 Those are some cool videos, they really highlight how the dot leaves the glass. At full speed it looks like the dot just goes up and to the left and quickly returns, without really seeing it leave the glass. But slowed down you can clearly see it leave the glass and return.

selecw Posted November 6, 2015 Author Share Posted November 6, 2015 Yeah the dot literally flies off the glass. I think in real time when you are shooting it's too fast to see and you just think it stays on. I need to make a video! Link to comment Share on other sites More sharing options...
yellowthunder Posted November 6, 2015 Share Posted November 6, 2015 Pretty flat from both. The super slow mo at about 40 seconds I could believe the dot staying in the glass. Don't forget they are shooting steel loads. Yes they are. From what I've seen the majority here think major loads shoot flatter than minor anyway though. That's pretty hard to believe. Around 140 to 150 pf my pistol certainly feels more controllable and "flatter" than at 169 pf using 115s. Steel loads are going to be much lighter and easier to control even though your comp is not working as hard. I do know people that run full pf loads in steel at local matches, but I'd be really surprised if they were doing that at that high of a level. They'd be putting themselves at a disadvantage.

R.Elliott Posted November 6, 2015 Share Posted November 6, 2015 (edited) That's actually the Bedell gun. 13.6 gr. Lil-gun with 124 gr. bullet. Pf was 170. I'm not shooting that load now; it burns too hot. N105 shoots about as flat without all the firery drama. Dot still leaves the glass though. What's cool about Shred's video is that you can also see the dot displace at the moment of ignition from the flex in the scope mount. You can't see this happen at full speed, yet it clearly does.

BeerBaron Posted November 6, 2015 Share Posted November 6, 2015 Funny I was saying the same in an email. The interesting part to me too was how the dot basically explodes as the shock wave travels through the scope body. It's inherent in a design when the dot is projected onto the glass. The dot diode and glass are joined by a piece of plastic so they can move independently a bit. It made me wonder if the alluminium body cmores deal with that better? I imagine they do.
