Great to see it's all worked out for you, lovely gun. Does the 7mm-08 still exist?
My drilling is dead. Long live my NEW DRILLING!

Oh yes, very much so. I checked the zero on it while I was at Bisley, and I'm glad I did because somehow it had dropped by a few inches. Still, first time in 7 years, so good going, and it's bang on now again. I don't currently have any stalking planned with it though. I'm trying to sort something out in France when I go there over Christmas.

An acquaintance ran the data through Quickload for me and according to his results, it should have a muzzle veolicity of 819 m/s or 2687 f/s, with an energy of 3262J or 2406 ft/lbs. Honestly, nothing much is going to recover from that this side of a bear.

Quite - and zero 4cm high at 100m and will be pretty much point and shoot out ti 230 and hold a wee bit high for 250.
And plenty of bears and other big animals have fallen to a 7x64 and 7x65r and similar such as 303 or 30-06.
Does yours shoot slugs to similar pointvof impact as the rifle barrel. If yes then yiu have a useful gun for driven boar as well.

No idea I'm afraid. It would probably take a test of a few different brands to find one it likes. Maybe I can find out in France this Christmas. I think the local gunshop has a 50m range. I'll see if my brother in law can sort out some hunting too. He's not usually very good at organising anything whatsoever though.

My Brother in law is also in France and his wife's family all hunt. They know I love hunting, but in the 20 years I have been married - well I am still waiting. Though in his defence He's good at organising lots of very good wine.

Could someone who has access to QuickLoad please run the data for me now that I have a full set of rifle measurement?
Cartridge:
7x65R
RWS brass
CCI Large Primer
49.1gr of N550
Bullet is a Degol Spitzer 150gr, but if that's not in there, it's a flat-based bonded hollowpoint with a secant ogive, similar to a Nosler Partition or a Sierra Pro-Hunter I believe.
OAL is 83.5mm
Rifle:
Barrel length is 24"
Twist is 1:10
Scope centre is 7cm above the centre of the rifled barrel
It's currently zeroed at 100m and I'd like the trajectory chart too if possible. Finding theoretical PBL would help too.
Thanks!

About 4kg, it's not a very heavy gun. Maybe more like 3.8kg. And sure, it lacks a moderator and it's never going to have a bipod. Think of it as a single shot rifle that also has shotgun barrels. I packs down very small and can do just about everything. But you know, I'm only an occasional stalker, it's not like it's an everyday tool. I find it adds pleasure to the rare experiences.

The older drillings and combination guns, especially the 16 bore ones do handle well - like a good side by side shotgun. And the rifle barrel shoots accurately as well - you should certainly hit a tin hat out to 200 yards
Given they usually have 26” long barrels they are not that noisy - certainly the 7x65r is no louder than 16 bore barrels. And as for a bipod, well i have handled a blaser bockdrilling that had a magnetic stud added for a bipod (bloody horrible)
But drillings are not prone shooting guns - they are much better shot standing or seated with you fore hand supported by sticks etc.

49.5gr of N550, not 49.1gr. Whoops.

PM - can' help with quickload, but looking a Vhitavouri's own Data - https://www.vihtavuori.com/reloading-data/rifle-reloading/?cartridge=98 - I would suggest it at 2750 to 2800 fps sort of speeds. 49.5gr is getting at the Max sorts of levels. The data has been done with Lapua brass - not sure how different in volume this is to RWS, but I the Norma 7x65R is not much difference to RWS in terms of H20 volume.
Using Hornady Ballistic Calculator at assumed Velocity of 2800 fps and BC of .490 with a 150gr bullet following results are attached. At 100 yd and 180yd (pretty the MRD for most 7x65r loads), with 2800 fps and 2750 fps velocities.

Someone ran it for me and it theoretically leaves the barel at 833m/s with a powder burn rate of 99.14%. Here's the trajectory. Basically if I zero it at +4cm at 100m, I'm good to 225m without thinking about it. Job done I think!

Yup, good old 1” high at 100 and if you need to a think about holding over etc - get closer

At the beginning of this thread? Or in the one I wrote after stalking a roebuck and a boar with this rifle in Alsace last summer.
Nice one, good photos too, health to enjoy
