3031 pressure trace

[Deleted]

I have looked and can't find much for pressure trace loads for 300 gain bullets and 3031 with clays as booster.

Was thinking 7/83 green dot/3031 300 sst

I'll be watching this with interest. Had a chat with Earnhardt (Josh) a while back when I was getting my new gun built and he said faster velocities could be achieved with this powder and still stay within acceptable pressure constraints. I'm always interested in something new.

Was going over some old pm I've had with a member and seen a load I was shooting that makes me feel the 7/83 load will be to hot. Thinking 7/73 will be in the safe zone.

3031 will build hellacious speed (if that's really a word) and with less pressure than many other powders, that being said, I'd go off of trace data or have someone run the loads on quickloads to verify you're in a safe zone. Then you can compare your actual speed to the speed quickloads figured and get an idea where ur at on pressure that way.

I shoot IMR 3031 in my rembrux with 275 and 300 grn bullets. There is a lot of trace data with IMR 3031 in the loads section. Not to get completely off topic, but I have always wondered why no one has used or tested H322 for similar loads? I know the 14/64 N110/H322 is used by several guys shooting the .50 ML II. H322 is close on burn rate chart to IMR 3031 just a tad slower. I have always wondered why H322 has never been mentioned along with the .45 cals?

I would have to admit that there are trace data for 3031 but seems like most is for 327 bullets didn't seen like there was much for 300 grain bullets.

I shot a load today that I believe was in the 60k range and blew a primer. Scared the crap out of me and won't be doing that again. Didn't realize I was that high on pressure. I should of checked but I felt I was okay.

I tried straight loads of 3031 and had three miss fires. I am running the savage plug with .040 bushing but it isn't enough for ignition on straight loads for me anyhow.

N110/H322 is hard to beat with a 275gr in a .45
11/59, 10/60 and 12/58 all shot one hole groups in my McRem .45 with 275 parker BE's and MH's.
That's the only loads I ever used in it.

Lots of folks have and still shoot that combo. "It is around, I guess it's just kinda old news now"

I believe H322 is a 'tad' faster than IMR3031 by about 4 steps up.  I think there been others that have used H322 in their .45's maybe they will chime in.

At the urging of DaveW I shot 11/59 N110/H322 and got great results with both 250TEZ and 275 BE's... Right around 2700 fps with both bullets...That was one of my favorites in my old Sav-Pac...If I had to stick with that combo I wouldn't feel left out....Trouble is that I like trying something different every year...like most here....H322 is a good powder in these 45's...If there was no 4198 that is what I'd shoot.

I'm assuming this OP is using a 45?

I remember when RB explained the whole reason for duplexing is because we are using light for caliber bullets, plus there is no resistance of forcing the bullet into the rifling. He also mentioned that there was a gap between pistol powders and rifle powders and this helped to bridge the gap. All that said, although I've shot my share of duplexes, I've never had any issues finding accurate loads with singles and reliability in cold temps.

My two favorite powders for 45 has been and still is H322 and 3031. Both have done everything I've asked and done it well. I used 3031 in my first 45 when trying to scratch the itch for achieving warp speed. Using a 250xtp I stopped when I was over 3100fps. Another time I was shooting 200yds and one load was an intended duplex and 300xtp. I had forgot the booster loads at home and was left with 5 vials of 53gr 3031. With easy loading bullets I managed a sub-moa 200yd group, although much lower impact at the slower speeds! All that showed me is that it ignites easily(for me) and the bullets still obturated just fine without the "need" for duplexes.

There was a 45 rempac I used to have on a cf action that just loved 300xtp's and 80gr H322. H4198 has worked, but I just never fell in love with it and therefor never used it much.

My go to hunting load was N110/H322 for several years in a couple guns, temp stability and accurate, couple others besides those that posted have used it with great accuracy in their guns as well.

Chad: I have played with it some but found pound for pound, you got more "bang" for the buck with 4198. I think I had shot it fairly recently in similar amounts as 4198 and my velocity was 100 fps slower. It would definitely be a powder to consider if 4198 disappeared?

Here's a combo using Blue Dot....it appears to be screaming right along?

Thanks rambler, I saw that one but what I noticed is with the 300 or bigger bullets the pressure was very touchy with load choices.

Ex. 7/80 would be in the safe zone (45k) and 8/80 would be way over 50k like it jumped allot.


However when you look at the pressure trace for 300 grain bullets it doesn't have much for info. Maybe I'm wrong just didn't see it.

Chad: Right now,I'm spending nearly all my time in the woods or up in a tree somewhere. I will work on some 3031 duplex traces with 300gr bullets sooner or later depending on how things work out. Because I don't have Green Dot, when I do get the time, will BlueDot be close enough for me to use as a booster?

[rambler]

Blue Dot will be close enough for me

Thanks for all you do TG!!

Thanks TG,

Yes blue dot will give me an idea where I should be, that's all I was looking for so I can stay safe.

I appreciate everything you do for us.

The load traced below seemed safe in my barrel under conditions present at the time but may not be under other conditions.

FYI

Three identical traces except for booster ( 14/50 with a 250 grain bullet ):


TG in PA         GRAIN                      FPS         KPSI     PSI/GR     FPS/GR     PSI/FPS    
N110/H4198     250     14/50     2775         39.4         616         43.4         14.2         
4759/H4198     250     14/50     2710         35.9         561         42.3         13.2         
BD/H4198        250      14/50     2800         42.1         658         43.8         15.0       


If you call N110 as 100% then:
4759 yielded 98% velocity and 91% of the pressure;
BD yielded 101% velocity and 107% of the pressure.
