Hillbilly, with that last two point something inch group I think you should be well satisfied. Doubles are not tack drivers, get out and enjoy the thing for what it is man! My Verney Carron O/U 375 Flanged Magnum does no better than that and it is brand new! Go get some biltong, and if you hit the left of the heart or the right of the heart who cares. Now, forget the groups, post a picture of this fine rifle for us.

Maybe before you re-regulate, try Woodleigh FMJ and or the same shaped soft and see what you get. They have the shape of vintage Kynoch rounds and may just work out for you. Many double users load Woodleighs because they regulate.
That is true of British rifles built before and shortly after WWII. However, the vast majority of Continental rifles were regulated with RWS ammunition (Austria is obviously Continental). Since the eighties, I suspect far more doubles produced anywhere have been regulated with Barnes than all others combined.

My Verney was regulated with 300gr Woodleighs.

That 58gr load is usable with open sights out to 50 meters are so. HOWEVER, if you can find someone who regulates doubles in SA, then that 57 gr load is what you are looking for. Have those printing together at 100 meters and you will have an awesome OU rifle.

I thought he was looking for ideas. I didn't know you had to be god to have one. Don't worry I won't bother from now on.

Progress report...

I tested a few more loads with the 230gr GS Custom bullet and increasing loads of S321. They got slightly better then started moving apart.
So I now have 2 options with this bullet/powder combo...

Option 1 is I can pick one load, which would be 60gr powder (I have not posted a pic of the results, but it was the best) and then play with seating depths and see where it goes,

Or, option two is to take the best load in the bottom barrel and the best load in the top barrel and load each as such. Effectively I will have two loads, the load that performed the best in each barrel.
Now I'm sure there are may out there who will say that is just not cricket! A double rifle should take one load and it should shoot acceptably in both barrels. I would agree with them.
But I must face reality, and it seems my rifles barrels don't point in the same direction for some or other reason.
The solution is to get them re-regulated by a gunsmith. But this is a costly fix, which I cannot afford.

So I have decided to go for option two, and load up two rounds for each barrel. The load that performed best in each barrel during all the testing (closest to POA).
I have given this much thought and the chances of me ever having to face a charging dangerous animal, with this rifle, are very very small.
Besides, I have another rifle which I use for that. And, in this country it is illegal to hunt dangerous game with a 9,3mm anyway, so this rifle has been confined to biltong hunting (plains game). Thus I cannot foresee my self ever being faced with a charge, in a time constrained, under pressure reloading situation with this rifle. I will probably have time to reload and still be cognacent of what I'm doing, and thus get the correct round into the correct barrel for follow up shots, if need be. And with practise and and correct placement of rounds in my ammo belt, it will become second nature.

So I loaded up 4 rounds, and I moved back to 60m, which is the distance I have decided I want this rifle to perform best at and be "regulated" at.
Attached below is the result of 4 shots, 2 from each barrel, from 60m. I think the far right shot was just me.
This group was under 70mm (2,7inches) at 60m. If the far right "flyer" was in fact me, the group would have been under 2 inches at 60m.
I'm happy with that :)

I will continue to test, with different seating depths of these two loads (as the bullet manufacturer recommends), just to see if the groups close up. But that will have to wait till lock down is finished, because I'm now out of bullets :LOL:

In the mean time I have acquired some 180gr Impala monolithics which I am going to test tomorrow, just to see what they do in my rifle...
Will post the results when I have them.

Why are you using S321 powder?

Hi Bob, how's things going in Wyong?. Down your way a couple of years back but haven't been in NSW since Ebor for the fishing. just getting over some nasty storms up here in Qld, seeing the sun for the first time in a few days. I'm going to NZ in the spring and hope to clean up a few buns while there and perhaps shake the spiders out of my old .303LE (currently owned by my BIL). Cheers Brian
