bsand Posted March 15, 2017 Share Posted March 15, 2017 Well I'm going to be making up a new load for.some Blue bullets that I've ordered. This got me thinking about chronographing and what distance should I be using the velocity from? Normal light ones are 10 ft away, should I be using the 10ft distance as my PF or is the muzzle velocity shown on the unit be the one I use?

Steve RA Posted March 15, 2017 Share Posted March 15, 2017 10 ft would be closer to what is used at matches to check PF. Link to comment Share on other sites More sharing options...
bsand Posted March 15, 2017 Author Share Posted March 15, 2017 Dang, that means I've got 300 rounds loaded to sub minor.. they were 128 PF at muzzle. Good thing I realized this before loading the 3600 blues I just ordered lol. Sent from my Pixel using Tapatalk Link to comment Share on other sites More sharing options...
darkvibe Posted March 15, 2017 Share Posted March 15, 2017 I use 10ft too. Sucks that you can't set the labradar to calculate for you at 10ft instead of the muzzle. Also 128 is cutting it too close of you ask me. Link to comment Share on other sites More sharing options...

Sent from my Pixel using Tapatalk Yes, I have mine set to 10, 20, 30, 40 and 50 feet but it will only calculate average, PF and KE at the muzzle. You have to calculate it yourself if you use the 10ft distance. At least I haven't figured out how to make it calculate all that stuff at 10 ft. 128 was your 10 shot average but at a match they only chrono 3. Plus your powder might be hotter or colder at a match. You're going to sub minor eventually. Link to comment Share on other sites More sharing options...

bsand Posted March 15, 2017 Author Share Posted March 15, 2017 You can see when you review the velocities when unarmed. I think you press the enter button and it'll toggle. I haven't played around with my labradar in months. Sent from my Pixel using Tapatalk Link to comment Share on other sites More sharing options...
darkvibe Posted March 15, 2017 Share Posted March 15, 2017 I just found the user manual online. PF is always calculated at Dx1. Link to comment Share on other sites More sharing options...

78Staff Posted March 19, 2017 Share Posted March 19, 2017 Is it 10ft after the bullet enters the cone, or 10ft from the base unit? (Assuming Dx1 is set to 10ft). Link to comment Share on other sites More sharing options...
bsand Posted March 19, 2017 Author Share Posted March 19, 2017 10 ft from unit. Sent from my Pixel using Tapatalk Link to comment Share on other sites More sharing options...
bwikel Posted March 19, 2017 Share Posted March 19, 2017 I just set my dx1 to 5 yards that way I can keep all my velocity measurements in yards out to whatever distance I want. Link to comment Share on other sites More sharing options...
78Staff Posted March 21, 2017 Share Posted March 21, 2017 I actually sent mine back - had all sorts of issues with it - readings from same pistol load same position same target ranging from 400-1200. Also missing lots of shots, again from same position. I though it might be that crappy stand wobbling around or the like so mounted it on my good heavy tripod and tried some more shots and got more of the same. Also the unit would just power off at random times. Plus, if using a ext. battery pack, you couldn't start a new series...had to power off an to do it. On internal batteries you could start a new series as the manual describes, so they still got some firmware issue to work out maybe, not sure. I know there are happy folks out there using them so I am assuming I got a bad one. Had the latest firmware and everything, so was pretty bummed. Anyway, took to much dang fiddling and and I got pretty mad at it lol so sent it back. Might just pick up another PC or may go ahead and get a 35P.

bsand Posted March 21, 2017 Author Share Posted March 21, 2017 I've had mine since December 2015. Since I upgraded the firmware, I also had werid readings for pistols, like 600 fps for a 40 SW loaded to Major. Right now if I shoot 10 rounds I'll get 7 or 8 shots recorded. Unit has been flawless for high power rifles tho. Sent from my Pixel using Tapatalk Link to comment Share on other sites More sharing options...
Steve RA Posted March 21, 2017 Share Posted March 21, 2017 I've got a Pro Chrono digital and a 35P and unless you are really into chronographing a whole lot I'd just get the Pro Chrono as it's less expensive, easier to set up and seems about as accurate as the 35P ( at least, mine seems to be). 35P has advantages but if you are just checking a PF once in awhile I wouldn't bother.

Sent from my Pixel using Tapatalk yeah I got that impression, I thought it might work better for long rifle - but didn't want to say b/c I didn't put a lot of time behind it, maybe 100 rounds. 21 minutes ago, Steve RA said: I've got a Pro Chrono digital and a 35P and unless you are really into chronographing a whole lot I'd just get the Pro Chrono as it's less expensive, easier to set up and seems about as accurate as the 35P ( at least, mine seems to be). 35P has advantages but if you are just checking a PF once in awhile I wouldn't bother. Yeah I started with the PC and I was seduced by the LR lol - I think I might just go back - you are right, dead nuts simple and inexpensive. M2 I was looking at also due to the remote display, but both much less than the LabRadar/35P and would suffice for my needs, mainly testing handloads. :).

I've put thousands of rifle rounds "thru" the radar not a single issue. Pistol has been a bit tricky, but I do not have a tripod, just the bench mount so I am having to kneel down to the bench level and shoot like that.

NicoR Posted March 27, 2017 Share Posted March 27, 2017 I was about to pull the trigger on a LabRadar just to measure PF in my pistol loads, but I'm puzzled right now. Why doesn't it work correctly for pistol rounds? Link to comment Share on other sites More sharing options...
bsand Posted March 27, 2017 Author Share Posted March 27, 2017 Don't know, maybe follow up shots were too quick? I did some load tests on Saturday, outdoor range 20 yards between muzzle and berm. If I waited until the speed appears I never lost a shot. If I just kept pulling the trigger it wouldn't register all the shots (8/10 logged) Sent from my Pixel using Tapatalk Link to comment Share on other sites More sharing options...
bwikel Posted March 27, 2017 Share Posted March 27, 2017 I haven't had any issues with 9mm picking up from either the bench stand or tripod. You do have to slow fire as the reset time is about 2 seconds. Link to comment Share on other sites More sharing options...
78Staff Posted March 28, 2017 Share Posted March 28, 2017 (edited) For me it wasn't so much the missing shots that bothered me (although I was waiting plenty of time between shots), every Chrono misses a shot once is while, but the LR seemed excessive, I mean it would miss 4 - 5 shots in a row then catch one, all same firing position, etc. The nail in the coffin for me was when the same load recorded a velocity range from 400-1200 from the exact same firing position/unit position - I knew something was off. That plus the random powering off, the new string issue - like I said, I probably just got a bad one, as there are plenty of guys happy with them and using them without issue. I just went back to a simple Pro Chrono which works fine for my needs, ie testing handloads. My hope for the LR was to be able to use it at the local indoor range which is much closer than my outdoor range travel wise, so I wouldn't have to go downrange to set it up like a typical Chrono (which you can't do at the indoor range), but I will just keep testing at the outdoor range, between pistols, rifles, and shotguns I tend to wind up there pretty much every weekend anyway :).

shriner Posted April 7, 2017 Share Posted April 7, 2017 I checked 45acp with my LR in two differant guns ( 1911 and HK USP ) off a branch with a 6" rest and it picked up all the rounds when the unit didn't time out . First time to use it - forgot about 2 second cycle and set the unit time short to save battery . Link to comment Share on other sites More sharing options...
