8x60

[DM Shooting]

Cheers guys dies are now on route so should be ordering powder and bullets soon.

 

[DM Shooting]

Well dies arrived and 10 rounds of test ammo was made in a crappy stock and a crappy trigger only using express sight she shoot all 10 into a 3" group.

So a little tittivation and all should be good.

I've just got my grubby mitts on an 8x60 specially made for Clas A Heyer & Co Nairobi. It's a nice little rifle and looks to have some hunting left in her.

Now on checking the proof marks for the bore diameter it's stamped 7,85.8,1.240 then under neath 8x60 with an S right angles lower down. Now I was expecting either 7,9 or 8,2 to say the.318 or .323

So what size bullets does she need????

I know this is an old post and I'm also only guessing here, but it almost looks like 7.85 was the original land/bore dia and 8.1 the groove dia. Not sure what the 240 is. But the dia markings would make it the .318 bore

Well I've slugged the bore and as per the proof marks 8.16mm so is that a sloppy 7.9 or tight 8.2????

Your thought please on these interesting old rifle.

A .321 groove diameter is definitely intended for the smaller diameter 8mm bullet, as available from Woodleigh, etc. An Imperial rifle groove measurement of .323 is the absolute minimum for use of 8mm S bullets UNLESS the grooves are wider than the lands. You might get away with 8mm S diameter boat-tail bullets weighing less than 175 gr but that would be entirely at your own risk. Bear in mind that the 8x60, in both versions, made its name with heavy round-nose bullets, as per the aforementioned Woodleigh 200gr bullet.

REMEMBER

The rule for cast lead is: .001 to .0015 larger than groove diameter.

The rule for cupronickel (or more commonly Luballoy equivalent) jacketed bullets is: .001 smaller then groove diameter UNLESS using boat-tail bullets, which, dependent upon shank length, tend to provide greater tolerance for tight barrels WITH SAFETY
OR, again, UNLESS the barrel grooves are wider then the lands.

For illustration, modern .308 Win and .30-06 rifles typically have a barrel groove diameter of .3085 inch. Every ‘.308’ bullet I have measured, i.e. Hornady, Sierra, Lapua, Speer; has had a diameter of .3075 inch.

240 probably refers to the standard 1-240mm twist rate, i.e. 1-9.45 inches.

Aha. I thought so but forgot to do the math...some old Mausers only list the bore diameter some do not list anything other than caliber....etc., etc....

Where is the pic of this rifle????

 

[Milan]

I think it was in the original post. Seems to be one now. Had barrel markings with the numbers mentioned above.

That's a nice one Mannlicher!

 

[sestoppelman]

Now how about an 8x64s!? I have ammo and dies but no rifle!

Then get a reamer, an 8x57 barrel (or whole rifle) and off you go.

 

[sestoppelman]

Easier said than done.

 

[Milan]

yeah I know. Obsolete stuff is not immediately available. I still have not loaded fro my 8x60...have brass and all the components. No dies, but I have 2 sets of 8x57 dies so I will just set one 3 mm higher in the press I think. I wish the classic cartridges and tooling were more available as they are quite easily keeping up with the new stuff in terms of performance, especially with new powders and bullets.

Rifles in this caliber are rare , even in Europe where this cartridge has never really established itself. After the WWII the competition from the cartridge 30-06 Springfield was so big that there was hardly any chance for the cartridge 8x64S Brenneke. The cartridge 8x57IS was still in service and the cartridge 8x68S was also available , latter with significantly more power as the cartridge 8x64S.

By the way , If you own a rifle caliber 8x57I or 8x57IS , you don't need to change it to 8x60 or 8x60S. The difference in performance between the two cartridges is very small and not relevant for hunting.

True but what a shame. While I love the 30-06, I think the 8x57 is just as good, especially with today's powders and bullets. Both are such cool cartridges but I never realized, till recently, how popular 30-06 has become in Europe. People either had 7x64 (some still 7x57) or 30-06 seems like. Many now probably have other calibers as well (300WM perhaps) but all the old dogs I meet have 06.

You have to search for a ZG 47 in 8x64 ! I also do, since a decade …...

@sestoppelman

I found a rifle for you !

[sestoppelman]

I have seen that one. Over priced and over there as they used to say. I don't like full stock rifles either. If I had that, I would whack that forend right off!

Here are the 'standard offerings' from the 1939 (U.S.) Stoeger catalog. Stoeger referred to the M1924/25 as "High Velocity".
No 8X64, but 8X60 , 9.3X62 and 10.75X68 were available 'off the shelf'.
