8x60s mauser

[bigrich]

hey fellas , i got a new toy coming ,and i'd like some opinions ,experiences , and possibly load data on the 8x60s mauser . brass is easily made by resizing and trimming 30-06 brass . the rifle itself is a 1947 brno 21H . set triggers , spoon bolt handle . classic euro type stalking rifle . i had considered just rebarreling into something else , 7x57, 6.5x57 or 257 bob for that mater . but i've decided to have a play with this old european caliber and see what it's got . projectile choice is really limited at the moment, but my local shop has some 170sst hornady's . i've seen these in action out of a mate's 8x57 and it was devastating on smallish pigs at close range . brno only made these in .323" bore , but i'll check it's not .318" bore first . any reply's will be appreciated . cheers

I will not be a .318 bore, but good on you for checking.
Any cartridge that is in between the 8x57 and 8x64 Brenneke, does not need rebarreling!!!
Go for it, who else that you know hunts with a 8x60..

I think 170 sst will be devesestating on any size pig at most ranges

some 196gn woodleigh would be great if i could get them , or 200gn speers

I. Bought a stack of Winchester factory ammo 308 that has wood Leigh protected point 180 grainers but I have heard they are super tough .super cheap A dollar per shot Buggered if I know what I’ll ever do with them I need to go elephant hunting

Mate I remember decades ago when woodleigh brought the protected points out the 180PP was one of the bullets tested on scrub bull. I think the other was the 235 or 270 grain PP in the 375. They had pics of the recovered bullets in their catalogue for years( maybe still do).

If it is stamped 8x60S then it will be 0.323" bore, the 0.318" bore 8x60 is marked J. Never hurts to check though. Still plenty of load data for this cartridge, and all 8x57JS data can be used. The only load I have in my notebook is a friends request of 250g Woodleigh, and 53g of AR2213SC which clocked 2300fps avg out of his sporterized Brno Vz24, that comes out at just over 2900 ft/lbs, pretty hard stuff.. He took it to the NT and reported good results on pigs, buffs and scrubbers. I checked load data.com and the 175g Sierra loads 53g of IMR4320 for 2700fps, 56g of IMR4831 for 2480 fps (user listed as MAX LOAD) and 52g of IMR4350 for 2300fps. You could also look at starting loads for 8mm-06 as a basis for the 8x60S Mauser, Cheers.

thanks mate , i pretty well much thought i'd use max loads for the 8x57 as a starting point , due to the extra case capacity of the 8x60 case . 8x60 is probably a lot more gun than i need for south east queensland game . hence my thoughts on rebarreling to 7x57 , 6.5x57 or the 257 bob . but as i have my trusty 7-08 tikka for such jobs , this old brno will remain as is probably . the only down side to the tikka is i'm limited to mild loads of 2209 with 150 bt's ,as the mag length doesn't allow me to seat out over factory 2.8" COL , and 2209 is a compressed load in the 7-08 . i should be able to seat 170sst's out to make good use of the 8x60 case however . 150 speer are also a useful projectile due to their construction, but it's not known for accuracy in the 8x57 .
as a side topic i found my sako 85 9.3x62 has VERY generous freebore , and i can seat right out to load over max loads with no preasure signs. i almost wish i got my 7-08 in a sako 85 for the better mag length. from the data i've looked at , i should be able to seat out as much as i need to in the 8x60 brno . the only thing that concerns me about the brno is scope to bolt clearance, and the timber stock . a lot of post WW2 euro made sporters had poor timber and they can be prone to cracking . with full power loads in the 8x60 this could make problems . i've seen a few old euro rifles for sale online with black "plugs" from stock repairs around the rear tang through the pistol grip . maybe put the original stock aside and get a hatchers .

This sounds like a very interesting little project

yes it is pete . after more research i'm considering rebarreling to 257 bob at some point. it's probably more suited to southern queensland game , and these old brno 21's weigh not much over 6 pound bare . it'l definately wake me up pulling the trigger on a warm 8x60 load with 200 speer's . specially with the euro hogs back stock . scope eye is something i'll have to be wary of

I like that weight ! I wouldn't worry about scope eye myself lol. It'll barely kick

yeah, the hogs back is good for quick snap shooting, and open sights . but the stock design means the recoil doesn't come straight back . the design promotes muzzle lift with recoil . i wear glasses too , so there's a little less eye relief . i had a 8x57 turk with a 20" barrel and that thing used to bark and jump around with 200 speers . light rifles are nice to carry , but don't help if it's a bit of a thumper . lots of fun but

I'll trade you for my 35 whelen lol

i'm 2.5gn over max with 250 barnes in my 9.3x62 . that's enough for me

[bigrich]

found a set of hornady 8x60s dies from "northern shooters supplies in victoria . their on their way

anyone have any experience with 150 speers in 8x57 ? i remember there's not much projectile in the case when seated . they didn't work for me in my old 8x57. just wondering if i should try some in the 8x60 ? i'm a bit reluctant to buy them if it's a long shot they'll work they'd be going quicker , maybe stabilise better for more accuracy . opinions ?
