Thanks. Did it screw right into the nut stud that came with your holster?

Those SROs with the Jagerwerks B.R.O.S. is a sick setup.

Thanks for the idea fellas. I might try to add a lock to my RHT. Anyone know the thread pitch for the RHT thumb screw hardware? 8-32? It will save me a trip to the hardware store. This is what I'm currently looking at on McMaster-carr: https://www.mcmaster.com/products/cam-lock-levers/cam-handles-5/

I just answered this question, and others you asked, in this other thread: https://forums.brianenos.com/topic/311544-which-red-dot/?do=findComment&comment=3427439

I've tried all three available heights of the leap when setting up an Aimpoint t2 on a different rifle. It's all personal preference on mount height, I personally like the lower 1/3 at 1.57". As @k2pichu mentioned, a lot of fellas like the tall amount as you have a more natural head and neck position. The tall mounts are also popular for people running night vision with devices mounted on their 12:00 handguard they want to look over. Some go as high as 2.2". You just have to know you're offset zero at different distances. A 3-yard target can have a 2-in offset that you will just have to remember. I usually just shoot steel at 12 to 20 yards so my point of aim / point of impact isn't really a big deal. The Holosun 510C comes on a mount that is set up for absolute co-witness, which would be comparable to the lowest mount you would see on an AR. You can get a Holosun riser / spacer plate to bring it up to about 1.60", which is considered lower 1/3 co-witness. This is how mine is currently set up. There might also be third party mounts, but I have no personal experience with those. I think the AEMS is it interesting option. The factory mount is a lower 1/3 co-witness. Holosun has the listed today weight at 3.9 oz. My 510C, with the spacer, weighs in at 8.93 oz. It does have a removable shroud, but I prefer to keep it on while on a long gun.

I have a 507 comp on my PCC now using a Scalarworks Leap/04. It's a very lightweight setup. They currently come in lower 1/3 co-witness height at 1.57" or a higher 1.93". They used to make an lower absolute co-witness, which you can still find on the used market. Any Trijicon RMR AR mount will work for your application. As far as a 45° offset amount for your venom, this arisaka mount, using plate one or plate 7, would work. It's spendy.

I was at a match recently where a shooter lost his 507 comp battery tray and screw in the middle of a steel challenge stage. We found the tray but could not find the little screw. I even took off my belt to use my magnet to sweep the ground but had no luck. I thought it would be nice to have a replacement in the range bag. I emailed holosun, with a picture of the tray removed from my optic and a second picture of the serial number. I asked to purchase the tray and screw and provided my info with the store I bought it from. They ended up sending me one at no charge.

I'm measuring the crimp at .372". We didn't get any tumbling issues on the 42 rounds we fired during ladder testing.

Update time! We finally were able to get to the range to test the ladder loads with 147gr and 160gr blue bullet round nose projectiles. We decided on the 160gr with 4.8grs of CFE-pistol for a somewhat spicy 138.6PF. It grouped the best of the 7 test loads with 4 of the 6 shots in the same hole at 18 yards, and it also had the best standard deviation. OAL was ~ 1.4775" and we used my 9mm Lee FCD just over the ogive. We pulled a couple bullets that were seated and I think they look ok and as I believe we didn't over crimp. Thanks for everyone's help! Here are some pictures:

Diligentia, Vis, Celiratis. Leave major alone! Before you know it, people will want .22LR in USPSA.

This goes against what is expected in rule 8.3.3: "Stand by” This command should be followed by the start signal within 1 to 4 seconds.It is recommended that the start signal be consistent for each string started for a given competitor—a cadence is desirable in Steel Challenge. The interval may change between competitors, however. In my humble opinion, it's almost like they want shooter push it and possibly false start.

Well that's good to hear! How do you determine the cause though, inspection of the housing for impact? What kind of turn around would one expect if it happened to fail while in warranty? I might get a larger MOA dot for steel challenge in the future. I tend to crank up my current 6 moa dot and get the starburst you talk about in your other post.

No worries, thank you for the reply.

I run Romeo3 Max's on two slide ride CZs and Frame mounted open gun. I considered your optic until I read this in the warranty: "Due to the fragile nature of the glass, this warranty does not cover the glass against breakage, cracks, scratches etc." I'm sure your optic would be fine on a open mount, but in the last year I have had two of my Sig's glass break on my CZs. A phone call and a few pictures to Sig and they have sent me new ones within a week. I couldn't give up that warranty.

Sorry, no I missed you asked about 38SC. I use mine for 9mm. Looking at the DAA page for the 2 in 1 die, it seems they sell theirs for 9mm/.38/.357 so I would assume the Hornady could work, but I can't say for sure as the crimp type might be incorrect. Would the Lee die 4n2t0 linked be what you need? https://www.grafs.com/retail/catalog/product/productId/102601
