I'm looking into IMR 3031 as a possible powder choice for my new Apex conversion. Have any of you guys used it as a single powder with 195 /200 gr. saboted bullets? Trying to get some feedback as to its ignition reliability and also some load data if anybody has any.
Reading thru some old posts on the other forum it appears some folks were having ignition problems. But from what I could gather, the problems were being caused more from their BP designs and Vent hole / bushing sizes.
I have Jeff's BP W/ .030 Bushing and the H.I.S. in my gun so I'm thinking I would probably be ok with ignition due to the design of Jeff's system.
Appreciate any info you might have to share.
Thanks,
YB

Sorry I can't help. I shoot 200 gr. saboted bullets but never any IMR 3031.

No problem nobody, appreciate it anyway. I may pick you brain for some different loads another time. Lol!

YB,
I have not used it, but when jeff did my encore conversion, I asked him what other powder i could use, and his reply was if i could not get 4198, his next choice was 3031, just needed to use a little more of it..
hope this helps..
(also on my burn rate chart, it's not that much slower than the 4198)..

Thanks Charlie. Yeah, the main reason I'm looking at 3031 is the extra volume it requires. I'm looking at powder options that will increase the height of the powder Colum in my barrel so I may be able to use my ramrod that is cut flush with the Apex barrel. Jeff said with 55/4198 & 275 BE the ramrod bottoms out flush w/ the top of the barrel with the "T" handle closed (straight in-line). Just trying to figure out what might work without hotrodding too much. Don't have any 4198 or 3031 at the moment so I can't measure out any loads for reference purposes.
Thanks,
YB _

I was just talking w/ Jeff in a PM and he cleared this up for me ... the 3031 Ignition issues were 209 primer related.
I'd still be interested in hearing of anyone's experience with this combo though, and any load data if you have any to share.
Thanks,
YB

I would suggest to you that 3031 is too slow for that combo, however I am running 245ish grain bullets in sabots with that powder so who knows.
You will be able to ignite that powder with your system.
I am not going to offer any load data because there is lots of data out there for IMR4198 and H4198 which are both much better suited to your bullet choice. My gut feeling is you will never be able to burn the amount of 3031 needed to match the velocity obtained with the 4198 loads.

Just sounds a little too slow for a 195/200 gr. saboted bullet? It might work out with a little 4759, 5744 or N-110 as a booster? I would go 10 gr. of any of the above boosters along with 55 to 60 gr. of the 3031.

Like Richard, I'm thinking you will need a booster. It may ignite well with
Jeff's system, but will there be a complete burn? Will you get the best
potential of 3031 with that light of a bullet?
I've come to like 3031 the best, but always duplex it with N110 or GD. A
load of 10gr N110 and 75gr 3031 under 270gr Emax's gets a velocity of
3035-3045fps out of a 28" barrel. That's telling me it is definitely getting
a complete burn. It would surprise me if you do not have to do something
similar with saboted 195-200gr bullets.

Well, based on the info you guys provided, along with a little more research, it appears 3031 is likely out of the mix as a single powder choice for 195-200g saboted bullets. I really do not want to duplex but appreciate all the helpful info nonetheless.
I'll just concentrate on working with proven loads for these bullets for the time being until I find what my Apex likes. Then I can make adjustments to the ramrod accordingly. In the mean time, I have another ramrod from my Savage that is plenty long enough to use at the range for load development.
Appreciate all the info guys.
Thanks,
YB

Have you seen the ramrod on SpinJags site? If I remember right it threads together and you can buy extensions for it.

Yes, I looked at those last night but they start out at 6" which is way too long for what I need. But they also sell smaller brass extensions that come in 1"/1.25"/1.5" & 2" that should work out well. I'll just work up my hunting loads then get whatever length will allow for the least amount of protrusion past the barrel.
Appreciate the info.
Thanks, YB

Buy yourself a piece of 7/16" brass rod and make your own. A 10/32" tap to thread one end and use your imagination for a palm piece.

Bill,
FWIW I do not shoot sabot, but I have burned a lot of IMR3031 in my .40 cal using a 209 primer and a custom 200 grain full form all copper bullet no boosters. I have shot this combo in hot weather to very cold weather with absolutely no failed ignitions. I have shot up to 78 grain and get velocity in excess of 3000 fps.
