| IMR 4831 SAFE FOR DOUBLES?? | Login/Join |
One of Us |
I've been reading Wright's book on doubles and he seems to say this powder can be dangerous for use in doubles, yet he has some loads listed with it. He's really confusing on the subject but is it safe to assume he was referring to older steel doubles and not new ones? Does anybody know the type and weight of powder Hornady uses in their factory loads? thanks guys. jorge USN (ret) DRSS Verney-Carron 450NE Cogswell & Harrison 375 Fl NE Sabatti Big Five 375 FL Magnum NE DSC Life Member NRA Life Member | ||

Jorge I have used it to good effect in my Krieghoff 470 no issues, shoots 4 bullets in a clover shaped hole at 50 yds. It is accurate and consistent.

Jorge....IMR 4831 is very safe when loaded correctly. It isn't a temp INSENSITIVE powder like the H4831 is, but there's nothing wrong with it. I like RL15 and H4350 for most of my reloads, but the 15 requires a wad...which is OK for me, but some don't care for that. If your gun likes it, no reason to change. Gary DRSS NRA Lifer DSC | |||

When I first got my 470 it was recommended I use R-15. I tired several different combinations to no avail. I finally tried IMR4831 and it worked great. I've since fired in excess of 700 rounds throught that 470 and have had zero issues with it. Unfortunately, it does have greater recoil but it works great in that gun. I've since used it with success in several 450/400s, a 500/450 and 500/465. | |||

Gents, thanks for the responses. I'm going to call Hornady on Monday and ask them what they use in their factory stuff like I mentioned. It seems one of our memeber told me once but I can't seem to find the thread.

Do the comments on the use of IMR-4831 in DRs apply to current manufacture H-4831? | |||

Like .470Evans, I have tried both RL15 with a foam wad and IMR 4831 in my .470. IMR 4831 seems to shoot better in my gun.

Jorge, Mentioned this before to you (if this is the thread you are referring to) that Searcy recommends IMR 4831 for the 450 NE. My biggest fear is when I die my wife will sell my guns for what I told her they cost. | |||

Yeah I remember now Snow. Got off my duff and looked at my own threads plus many PMs from a lot of you great guys and got most of the answers. Anyhow, thanks to all of you again. jorge USN (ret) DRSS Verney-Carron 450NE Cogswell & Harrison 375 Fl NE Sabatti Big Five 375 FL Magnum NE DSC Life Member NRA Life Member | |||

Jorge The Hornady factory load for 480 DGX is 95.5-96 grs. of H4831 for mv of 2120. H4831 works very well in my 450 IMR4831 works very well in my 450/400. | |||

thanks 450. I'd forgotten you had been kind enough to furnish that for me before. As you can see, my rifle liked .5gr less with IMR and a bit less MV for the group above. Also CCIs. I'm going to try and see how Woodleighs shoot for the hell of it as well. Also, at least I'm putting this Sabbati through an endurance test, 100 rounds and it hasn't "blowed up" yet!

Jorge, As nearly as I can tell from reading up on IMR-4831 (which I use exclusively in a 500/450), danger only arises when you do not have good loading density; that is, when you leave a lot of air space in the cartridge because either it is too big, or because you foolishly try a reduced load of IMR-4831. Low loading density risks to flash the flame over to the front of the powder load rather than to burn it rapidly and evenly from the point at the base where the primer fires. This causes a detonation rather than a burn. This is the reason why any powder,notably including RL-15, must have a light wad on top of the charge if it does not fill up most of the brass. The foam or dacron wad keeps the powder tightly packed for an even burn. In a 3-1/4 inch brass case such as is used for the mid 40s calibers, IMR-4831 IS SAID to have appropriate loading density to avoid problems. Regards, Tim | |||

Thanks again for all the help guys. On the other thread I posted that I managed to open a factory Hornady DGX and found out their load was 93.7gr of H-4831. So far both IMR and H seem to shoot to regulation, so I'm going to try and load a few with both powders and Woodleighs to see where they shoot and report back. jorge USN (ret) DRSS Verney-Carron 450NE Cogswell & Harrison 375 Fl NE Sabatti Big Five 375 FL Magnum NE DSC Life Member NRA Life Member | |||

I would caution the comparison of factory loading for the purpose of hand loading. I expect hornady purchases power in large lots direct from the manufacturer. The burn rates are tested for that specific lot and the powder charge is adjusted accordingly. While it may indeed be H-4831, the load you mention above may or may not be the same for that same ammo produced with another lot of powder. As many have noted before, power can vary significantly from Lot to Lot. I am amazed at the variation I have seen in RL-15. For doubles I recommend you find a specific power that you intend to use, and buy a 8LB jug. That way you can work up a load for that powder and not have to make any changes for some time. Bottom line, consult the reloading manuals and work up from a known safe load listed in such manuals. Jorge you appear to have found the magic load for your rifle with your specific lot of powder. Congrats on the work….and as a side benefit, you were able to shoot your double over 100 times in the process! Aint it fun! ****************************************************************** R.

IT's been a lot of fun that's for sure! Regarding the powder differences inherent in different lots, yes I was aware of that as well. Another consideration as to why the factory loads perform with what appears to be less powder (by about 1.5gr) is the fact their bullets are heavily crimped and that will definitively bump up velocities. I have a crimping die I can set to duplicate that so my intentions are to load that exact same charge with Hornady DGXs and F215s and go from there.

I don't reload, nor do I know anything much about powders. I only know that in Safari Rifles II, Craig Boddington recomends IMR 4831 with a bit (a half grain) of (polyester) pillow stuffing as a filler. He says he has experienced erratic ignition without the filler. But not to get too heavy handed with the filler, as pressures can (will) go up alarmingly. Thats all I know, hope it helps. ------------------------------------------------------------------------ He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him. -- John 3:36 http://www.accurateinnovations.com - http://aigunstocks.com/home-2/ NRA Life Member DSC SCI DRSS - STILL waiting on MY "Taksdale" .450NE or a refund...

Jorge, I load IMR-4831 for my VC .470NE and after many rounds have had no issues; consistent velocities, shoots well, low pressure. I also load it for Nganga's .450-.400NE and .500NE and it is equally as good as it is in the .470 as it will be in the .450NE. As another poster stated the problems arise with reduced loads, as long as you maintain good load density you will have no worries, a wee bit more recoil than RL-15 but it is worth it to me not to have to fool with wads. Good luck! | |||

Thanks! I must say this rifle fits me very well. Even off the bench it's no problem working up loads. jorge USN (ret) DRSS Verney-Carron 450NE Cogswell & Harrison 375 Fl NE Sabatti Big Five 375 FL Magnum NE DSC Life Member NRA Life Member | |||
