Spanish Double Rifle Regulation Load
      #287003 - 26/08/16 03:31 PM

Looking for any info about load used for regulating Ego double rifle in 9.3x74R manufactured in 1990?

I have had 3 different 9.3x74R doubles, and all shot well with 63grs AR2209 and 286gr SP Norma projectile or 270gr Speer. I'm hoping my current one will shoot the 286 RNSP Woodleigh as I bought 500 of them. Provided the rifle was regulated for the heavier projectile and not 230 gr lighter ones then you should not have too much trouble with it.
Good Luck

My pet load for my Merkel 9.3x74R is f/l resized RWS brass and 57.4 grains of Varget and a 250 grain TSX or TTSX, and a Winchester large rifle primer (non magnum). I'm pretty sure that Varget is the North American label on A2208 powder.

For those with a Harrel powder measure, the setting I use is 100.0 0/3 culvers....

With this load, I get a perfect side by side 1 inch composite group at 100 yards, perfectly oriented right and left on a horizontal plane. This rifle is my most perfectly regulated double when using this particular load. The rifle can sometimes demonstrate slight stiffness of the top lever on a really hot day - indicative that I'm riding toward the edge of a hot load in this rifle.

The factory target shows a ragged one hole group at 50 metres with RWS 286 grain loads, but I've never been able to even remotely duplicate this with 286 grain bullets. The 286 grain bullets orient diagonally and I haven't managed to find a powder that brings the shots together. The 270 grain Speer bullets get the groups tighter than the 286 grain loads, but are still dismal. At least the 270 grain bullets are more horizontally oriented, but are still not great.

In any event, every rifle is different with its own unique personality, and this attribute is much more highly pronounced with double rifles when developing suitable loads that regulate properly.

LesLeeSpeed & Postman, thank you for info on loads.

Using Graeme Wrights book I have worked up load using AR2209 that regulates well. Just out of curiosity I am looking for info on load or bullet weight used in factory regulation.

Factory regulation will vary by manufacturer. Some will choose a load that either "they" create themselves, or they may use a load commonly found at the time of manufacture, or they may use a load specified and/or supplied by the client. Witness the Heym USA website where they specify modern and currently available Hornady loads in some of the calibers they offer. When I ordered my rifle from Heym, I supplied not only the measurements to them, but I also specified the ammo I would be using. I chose ammo commonly available today. Some makers like Merkel supply a test target where they specify and identify the load used for regulation and show you where and how the loads printed on the target.

I wish there was an easy answer for this but you would likely have to go back to the manufacturer with your rifle's serial number and ask them.

Something that was interesting to me was, the shape of the bullet nose effected regulation. My Sabatti rifle was regulated with Hornady Factory 286gr spritzer, however it would print the left barrel about 2" higher than the right. I switched to a round nose and they became level at 50 yds. As to loads you might try H414 with a 286gr Woodleigh or Privi Partisan and Win/rifle primer. I used Hornady loading data to develop this load.

Postman, unfortunately going to the manufacturer for the info is not an option as they went out of business around 2006. Thank you for your time and advice.

Bob, thanks for info on bullet shape, so far most of bullets I have tried so far have been semi spitzer, going to try Woodleigh next. Luckily I have worked up a load that regulates OK so far, just trying to see what else is out there and whether it will perform better. Although lots of Privi ammo and components available locally none in 9.3x74R though.

Good luck with the load. I've found that H414 aside from being the most accurate load in my rifle, it produces lower pressures than other powders recommended and a full case, that is slightly compressed. All of which are positive in my mind.

Thanks aromakr accurate and low pressure, must try and get hold of some H414 to give that a go.

Hi NZhunter,
You might like to do some checking, but I believe Winchester 760 is the same as H414. Hogden powders are like rocking horse shit here in Australia.

LesLeeSpeed, cheers for that, availability is why I have tended to concentrate on ADI powders for all my reloading.

There will be a considerable chance it will have been regulated for a 230 gr or similar weight projectile.

Hopefully not as the 286 gr or similar regulated rifles are more useful.

Still a chance some acceptable load with the beavier bullet might be handloaded to work well enough.
