B_RAD Posted March 9, 2017 Share Posted March 9, 2017 (edited) All 10 of my bottles are the newer, slower batch. I've chronoed 30 rnds out of my SP-01 and they averaged 842 FPS. 3.2 PV 147 Xtrme @ 1.135". I was able to get quite a bit more velocity out of my Tanfo Lim Pro but the CZ isn't as fast. I'm gonna try 3.4 and 3.5 and see if that gets me 890 average. Anyone working with the 16055 batch and CZ barrels?

MemphisMechanic Posted March 9, 2017 Share Posted March 9, 2017 All I know is that around here when I see "PV" I think Powder Valley, not Nobel Sport Prima V. Link to comment Share on other sites More sharing options...

You are using a coated bullet and I'm using a plated but you're average is 50 FPS faster. What was what I was getting with my Tanfo. I chroned these over two different days. I stood 10' from the chrono and the sky was overcast on both days. Got the exact same velocities (averages) on both days. Now im starting to think maybe I didn't do something right? I'm gonna try these again. Gonna use my RCBS chargemaster to dispense exactly 3.2, 3.3, 3.4 and see what I get. Link to comment Share on other sites More sharing options...

B_RAD Posted March 10, 2017 Author Share Posted March 10, 2017 (edited) Shot 20 rnds today out of SP-01. 147 gr Xtrme. 3.3 gr Prima V. Win primers. OAL was 1.130" Lowest was 865 fps. Average was around 878 and SD was 11. I accidentally hit delete string before writing the info down but I do remember the LO and SD. I measured all 20 rnds after loading. The shortest was 1.122" and the longest was 1.139". That's a little more than I want. I was loading on my 650. Gonna load up some more on my 1050 w/Mark7 next. That should help elimate any issues with me pulling the handle inconsistently. Edited March 10, 2017 by B_RAD Link to comment Share on other sites More sharing options...

wlt Posted March 11, 2017 Share Posted March 11, 2017 (edited) Primers completely normal. Every brand is a little different. Winchesters are softer but they are normal.

Fantom919 Posted March 14, 2017 Share Posted March 14, 2017 Just got a 11 lbs of this same batch yesterday. Going to try and load up and test some 147 zero jhp and 147 bayou. It will be through 2 accu shadows and a cts lsp so hopefully we'll get a bit more cz barrel data in the mix. Link to comment Share on other sites More sharing options...

I'd guess 3.2 will work for you around the 130 pf. 3.3 was getting me a min of 127 pf. Link to comment Share on other sites More sharing options...
Fantom919 Posted March 14, 2017 Share Posted March 14, 2017 I'm going to try 3.2, 3.4, 3.6. I'll probably just try with the JHPs since they're slower. I just load the molys with the same amount of powder for practice. I'm also perfectly fine shooting a bit hotter. I think I was at 135 pf at area 2 which was fine for me haha Link to comment Share on other sites More sharing options...

You are using a coated bullet and I'm using a plated but you're average is 50 FPS faster. B_RAD, that's not weird. Lead and coated lead obturate better than jacketed and plated and contain more gas/pressure and thus generate more velocity. Also, that BBI is seated down around .290 into the case (probably more), and your XTreme is going to be seated shallower. That smaller initial combustion chamber size is going to earn him higher pressures the whole way up as well. AND BBI have anecdotally been a little over-sized at .357, which again, better obturation than even other brands of coated lead. 50 feet/sec difference going from 147gr lead to 147gr plated is not surprising. You aren't seeing anything anomalous here. Link to comment Share on other sites More sharing options...

After all my plated bullets are gone I'm thinking of going jacketed. That'll be more more velocity drop. Link to comment Share on other sites More sharing options...

Fantom919 Posted March 16, 2017 Share Posted March 16, 2017 Oh wow. I'm running zero JHPS at 1.15. I'll probably have to bump it up and try 3.4, 3.6 and 3.8. Link to comment Share on other sites More sharing options...
Fantom919 Posted March 18, 2017 Share Posted March 18, 2017 What kind of deviations in grains are you guys getting? I started to shoot for 3.4 then it slowly crept up to 3.5 and seemed to finally level at 3.54 to 3.62. Fairly inconsistent from what I've seen from Titegroup but SD in velocity will be the true test.

Prima V takes a while (around 100 throws) to get settled in the hopper and start throwing consistent charges. Also every load session I do about 5-10 throws before I load an actual case.

I have a hair clipper zip tied to my powder holder and was hoping that would settle the powder while I poured it. Now I'm wondering if the different sized pebbles and the vibration will make the smaller and larger ones separate top to bottom. Link to comment Share on other sites More sharing options...
Fantom919 Posted March 19, 2017 Share Posted March 19, 2017 (edited) Here's my data from today's chrono run. I have 2 CZ accushadows (CZ1 and CZ2) and 1 CTS LSP (Tac Sport slide so longer barrel). CZ2 has historically had a faster barrel than CZ1. All rounds are loaded to 1.15 OAL with 147gr Zero JHP 3.5gr CZ1 High: Low: Ave.: S.D.: PF 898.9 864.6 878.1 9.2 129080.7 CZ2 High: Low: Ave.: S.D.: pf 912.2 862 888 13.5 130536 CTS High: Low: Ave.: S.D.: pf 920.6 888.7 905.7 9.9 133137.9 3.8gr CZ1 High: Low: Ave.: S.D.: pf 952.2 906 926.27 10.9 136161 CZ2 High: Low: Ave.: S.D.: pf 940.6 922.5 932.665 5.1463 137101 CTS High: Low: Ave.: S.D.: pf 961 944.5 951.6 4.4 139885 4.0gr CZ1 High: Low: Ave.: S.D.: pf 989.3 946.1 958.7 10 140928 CZ2 High: Low: Ave.: S.D.: pf 982.3 950.1 965.8 7.5 141972 CTS High: Low: Ave.: S.D.: pf 999.4 970.6 979.9 6.8 144045 Everything shot a little faster than what I expected from what others had posted. Some strings had some extremely good SD while others not so much. I'd say overall SD is better than Titegroup from what I've seen. Based on the FPS differences at different charge weights, I'm getting roughly 15FPS faster per .1 gr which is maybe just a tad lower than TG. I'd probably shoot for 3.6 to be way safe since I have no idea how this power reacts to temperature and elevation. One thing I did notice was that when I compared off hand accuracy at 25 yards with the 3.8gr to my current match load (Same bullet and OAL, 3.45gr TG 134pf), the Prima V was not as accurate as the Titegroup. To be honest I never really understood how one powder could be more or less accurate (and still don't) but the results repeated themselves. Obviously I'm the biggest factor so I'll try and get someone else to shoot and confirm. Anyone else compare accuracy in powders? In any case, for the time being I'll stick with TG for my match loads and use this powder for my practice moly practice rounds. Should help reduce the smoke and high heat of TG. (Do a few back to back bill drills and the gun gets hot quick!) Edited March 19, 2017 by Fantom919 Updated PF. Excel Sheet copied them incorrectly.
