Chasseur -thanks - I have some Hornady data for the 7x65r max load is c52 to 54 gns depending on powder - 57gn looks quite a punchy load, but by all accounts on paper it seems to work for you. Appreciate load data is developed in just one barrel and all barrels are different. Do you get any pressure signs with that load?

Heym,

I made a typo there, its a 47.0 gr load, I've also had good luck with 47.5 grs. These give me 3 shots touching at 100 yards/91m.

Yes 57 would be a bit much for a 7x65r...

Thanks for clarifying -thought it must have been a typo as 57 gn would be a struggle to get into the case! Will give it a try

Firstly, I have a 7x65R in a break-open gun!

What I think is the origin of this warning is that, it is commonly given advice for break-open guns that, if shooting cartridges of either 7x65R or higher recoil, that only steel actions should be chosen. Dural actions, (i.e. lightweight aluminium actions), are considered to be more prone to eventually shooting loose with 7x65R and up.

This is a generalization and some Dural actions will have steel inserts to reinforce critical areas. Also, some of the new Blaser firearms, for example, have more elaborate lock-up systems. So I'd take this as advice to keep in mind rather than an unbending law of physics. But if you are looking at a classic Drilling, for instance, and the action is Dural and the cartridge 7x65R or more, I'd certainly think about it.

This info was given to me by a friend of mine, Klaus, who is currently at the German IWA show and who imports older European guns.

My steel frame 7x65R is still 100% tight, incidentally. It has an old-silver finish which suggests aluminium but a magnet shows otherwise. The 7x65R and it's rimless twin the 7x64 are very similar in capacity and performance to the .280 Remington and not too different from the .270 Winchester. So there's nothing wrong with the cartridge. In fact, I recommend it.

Had another great hunt with my 7x65r drilling last weekend, two chital stags.



Here the recovered bullet from the second stag. The first was a neck shot so the bullet went through. I'm not a fan of the neck shot but he poked his head up along the side of the hill I was only about 50 yards away so beggars can't be choosers...

Its a 7mm 154 gr. Hornady. It was a quartering towards me shot, across a small gulch or valley. Bullet went in through part of the left shoulder and lungs and then deflected back through the paunch stopped at the skin on the other side. The musheroomed bullet is about 134gr, so it lost about 20 gr in the animal. Not bad for breaking the front shoulder and then going through most of the paunch/ruminant material.

I would avoid any gun that uses non-kipblock action in dural/aluminium as trouble will come sooner or latter.

Personally, I would love to have a kiplauf in 7x65R made on a Jäger kipblock design like those made by the H. Schering. But, I would want an more classic english style than the über Alpländishe style so often seen.....
