Does anyone here have any 9,3x74-R pet loads they will share that they have used in their double rifles?

I have Accurate, Alliant, Gevelot, Hodgdon, IMR, Norma, Vectan, and a few other powders available for my use...so will appreciate just about any data you may have.

TIA,

AC

So far, the best load from my Tikka 512 O/U is 55grains of IMR 4064 with the Speer 270 gr. bullet. 4 rounds (two from each barrel) shoot inside 2 inches at 100 yards. The load is quite mild as well, but bear in mind the Tikka is a fairly heavy rifle.

How far does this 4064 load fill the 9,3X74 case? To the base of the neck? Packy

Peter -

Thanks very much for your info. It is much more significant AND directly relevant than you mght have suspected.

I have been using 57 grs. of IMR 4064, behind 286 grain Norma bullets in RWS cases, and have had the feeling the load might be just a wee tad hot. I was thinking of going to 55 grains (your exact charge, coincidentally) instead of my usual 57. Now that I see you recommend 55 grains for slightly lighter bullets, I think maybe I'll drop my load to 53 grains for openers, and then also perhaps try 53.5 and 54.0 grains. That might just be high enough with my 286 gr. bullets.

BTW, I am shooting these in a Valmet 412, which is very nearly identical with the Tikka 512, so even the gun you are using the load in is very relevant to me....

Thanks a BUNCH!!

I have submitted some loads at reloadersnest.com


But beware! They are with molycoated bullets.

Niels - Thanks for pointing out that re-loading site. I was not aware of it.

Senor Pak Rat Regis, that is...

I don't know about to the shoulder, but if using 285 grain Norma bullets in MY RWS brass, 54 grains of IMR 4064 fills the case to the base of the bullet, 55 grains is very lightly compressed, etc. That is with the mouth of the case crimped into the bullet crimping groove......

A C. Sounds like a load to try. I'm out of 4064 though. I now use mostly Varget for those kinds of loads. I buy 8# bottles at a time. I wish I knew how that volume of Varget equated with 4064. You can be sure they are close but not near enough to interchange. Lots of possibilities there, ie. excess pressure. It is unneccesary to ruin a good double. Thanks for the heads up. Was in KC yesterday and would have bought some for sure. I did find a box of Barnes X 9.3mm 250 gr. If they are unsuitable I will use them in 9.3X57 to increase the velocity some. It is a 96 Swede so you can't go to high intensity. Back to the X74 I will have to make a trip somewhere for some 4064. I can spend less than the HazMat fee and drive my hotrod to a small supply store for powder. Double the fun Even in snow. Good luck with the double and God Bless. Packrattusnongratus

You are wellcome. Enjoy!

65 gr of H4831 is my first load with either a 300 gr aframe or a 286 grainer. 54 gr of RL15 is next with either bullet. the 300 and 286 both hit the same impact point

If I had no data for Varget (which is the situation right now) , I would drop the load to 50 grains as a starting point with the Norma bullets, 49 grains with the Barnes-X. One can always go up, but sometimes it is too late to drop the charge down, as you know....

Just as a matter of interest, and lots of people get upset when I say this, I have often found my best accuracy with LESS THAN a 100% fill of powder to the base of the bullet. Not much less, but a grain or so. Seems like a 96-98% fill seems to work best in many instances in MY guns.

My way of saying that if I was you, I'd start with 53 grains 4064, not 54 or 55 grains. As above, you can ALWAYS increase the load if circumstances merit.

Good luck.....

I agree. It all sounds like good advice. I usually start low but consider half way between the low and high book loads as my maximum. Usually as I hit MY max. load I also hit acceptable accuracy. It usually works that way. Packy

H 4831/68.0 behind a Norma 285 PlasticPoint. This heavily compressed load groups both bbls. of my FN-Browning into less than 1". Its also a good expanding load for drive hunting wild boar.

Thank you Andre - BTW, are you THE very famous Andre Mertens of Belgian gunmaking fame? If so, I will for sure try that load. If you are he, you should certainly know what works....

RWS berdan cases; RWS 5608 primers; Reloader 15,
55 gr.; SPEER 270 gr S-Spz bullets; O.A.L. 3.596"
Very good accuracy at 50 mts (Chapuis double barrel).
