ViktorCistic Posted May 9, 2007 Share Posted May 9, 2007 Hi folks, I have lightening slide and i need recommendation for load. The slide is very quick. Currently i use 180grs FMJ bullet, but - FTF. With my old slide (full weight) no problem. Should i use light bullets (165 ?) and faster pwdr than 180grs bullets ? THX Jakub Link to comment Share on other sites More sharing options...
Brazos SC Shooter Posted May 9, 2007 Share Posted May 9, 2007 I just bought a Brazos SC Limited gun which also has a readically lightened slide. Bob recommened the following two loads. 3.9-4.0 grs N320 w/ Precision 185 gr at an OAL of 1.22 or 4.8 grs of TiteGroup with same bullets and same OAL. I have only shot one match but I used 4.8 grs of TG under 180 gr Ranier jacketed FP at an OAL of 1.225. I haven't chrono'd this round yet but the gun ran amazing.

Matt Cheely Posted May 9, 2007 Share Posted May 9, 2007 I use the same load no matter what the slide weight is. Link to comment Share on other sites More sharing options...

Texas HK Shooter, Are you making major with 3.9 to 4.0? I am loading 4.4 Grains of VV 320 with precision and my PF is 171 . Gun is Benny Hill 6 in.

Gun is Benny Hill 6 in. I thought that seemed light too. I was running 5.1g of 320 to get 166pf or so through my 5" gun. Link to comment Share on other sites More sharing options...
Mick Posted May 10, 2007 Share Posted May 10, 2007 (edited) I use 5.0 of N320 and a 180 @ 1.160" for about 950 in a 5" gun. Speaking of light weight slides, my 5" "fat free" is my favorite of my 3 .40s. The slide is about 10.5 oz and I run that same 180 load in them all. I think the "fat free" is the best shooter of them all...It cycles real fast. I also load a 185 PB with 4.2 rgains of N320 to make major at 1.165" Edited May 10, 2007 by Mick Link to comment Share on other sites More sharing options...

I haven't run them through the chrono yet, these were just the recommendations that came from Bob when I got the gun. Also, I am not using the VV receipe, I am currently using 4.8 grs of TG.

DougCarden Posted May 10, 2007 Share Posted May 10, 2007 Jakub, you can shoot whatever load you want. You will have to balance out the springs in then gun now, as the slide will cycle faster. When I lightened up my slide I went up to a 15lb recoil spring with a 17lb mainspring with my 165gr load. The gun now tracks neutral in my hands with a proper grip. You can also go up on the mainspring weight and a lighter recoil spring, but it will take some experimentation to find what works best for you. Good luck, DougC Link to comment Share on other sites More sharing options...

BNorth Posted May 10, 2007 Share Posted May 10, 2007 I agree. I'm using 4.5 of TG with a 185 PB at 1.200 which made 168 at the AR Sectional through a 5" gun. Link to comment Share on other sites More sharing options...

Ditto, My friend's load for his para. 4.2 grains TG at 1.160 185 PB & he was he was making 174 PF. Edited May 11, 2007 by bulm540 Link to comment Share on other sites More sharing options...

Like I said, I will taylor the load after I get some chrono data. I will report back once I have more info. Link to comment Share on other sites More sharing options...

Good luck, DougC DougC, currently I have on my old slide (full) 10lbs recoil spring+ Sprinco + 15lbs mainspring. PF 175. Works perfectly. But, when I change slides, I have FTF problems.

HSMITH Posted May 11, 2007 Share Posted May 11, 2007 Sounds like an extractor issue with the new slide. Link to comment Share on other sites More sharing options...
ViktorCistic Posted May 11, 2007 Author Share Posted May 11, 2007 I dont think so..this is Aftec extractor, from my old slide. Works perfectly. I have suspicion about selection correctly powder and bullet. Lightening slide is very quick, and i have slower pwdr - Ba9. Link to comment Share on other sites More sharing options...

scooterj Posted May 11, 2007 Share Posted May 11, 2007 the firing pin stop may not be fit correctly. try the stop from your old slide. Link to comment Share on other sites More sharing options...
DougCarden Posted May 12, 2007 Share Posted May 12, 2007 .....I think you need to go up on your Recoil spring weight, try a 14-16lber........ DougC Link to comment Share on other sites More sharing options...
ViktorCistic Posted May 14, 2007 Author Share Posted May 14, 2007 Doug, bad news for me but i should try your recommendation. Thanks Jakub Link to comment Share on other sites More sharing options...
Brazos SC Shooter Posted June 10, 2007 Share Posted June 10, 2007 4.8 gr Titegroup seems like allot of powder for a 185 Precision molly I run 4.4 gr with a 180 bear creek moly and chrono 170.4 OAL 1.17 4.8gr sounds like a good load for Precision Delta FMJ YMMV Good to know. Like I said, I will taylor the load after I get some chrono data. I will report back once I have more info. I have finally been able to chrono some rounds. Turns out, 4.7-5.0 are all too much. Here were the results from today. OAL was 1.225 185 Precision TiteGroup Powder 4.7 - avg 185PF (This load made 170 with a 180gr Ranier RNFP fully jacketed bullet) 4.8 - avg 183PF 4.9 - avg 184PF 5.0 - avg 183PF This just doesn't seem right. I was surprised to see these changes in powder not really change velocities. My Standard Diviations were so small that I feel confident in the quality control of my loading process. Now I am at a loss as for what powder to use to get down to 170. I saw 4.2 but it was for a shorter OAL. I will keep searching. Link to comment Share on other sites More sharing options...
