New 8x57 Mauser

[bns454]

Hello Everyone! I just bought a new Remington 700 in 8x57.I hope I didnt ruin it by shooting j-word projectiles in it.I want to buy a mould for it but have no idea where to start.I was hoping someone here has the same gun and can give first hand experience on what mould to never not buy or one that works better than another.I have never cast or shot any lead boolits for rifle,only revolvers.I have not slugged the barrel yet.I tend to always shoot heavier weight projectiles in all my guns.Any opinions on what to start with would be much appreciated.Thanks

I'd start with the inexpensive Lee 175 gr other guys are having good results in milsurp. 8mm's no reason your Rem shouldnt do as well or better since you prob don't have to deal with huge throat or worn bore issues that military surplus rifles generally have . Should be a shooter .

I like the Lee Karibiner mold in my old spanish 98.

[runfiverun]

you don't have a big throat in the 700's.
but if your bore diameter is on the smaller side this one will work perfectly.

if it has the 314 bore diameter this one is better suited.

you can order the first one with the bore diameter in mind and have it cut for light engraving on the nose section.
that would be the preferred boolit.
and is what I done.
pushed along with 30 grs of imr-4895 you'll get all the accuracy the rifle has to offer.

Post #4[and have it cut for light engraving on the nose section.
that would be the preferred boolit.] Do you mean have the mould cut to match the gun,or alter the boolit nose after cast ?

[bns454]

Ok,I I just found posts on pound casts,I will read those more,but I need to get 1 mould first to do the casts.

[runfiverun]

you just need a slug of dead soft lead and a case full of harder lead to pound against.

this is one time most of the work is done for you and all you need to know is your bore diameter.
i'll lay money down that the groove diameter is 323, and a 324 size die is all you'll need.
push a soft 325 diameter slug down the barrel and get your bore/groove measurement.

the only thing slowing you down at that point is clearly communicating with Tom what you want the mold to pour with your alloy.
and hoping Remington cut the chamber in-line with the barrels bore. [they didn't on mine]

[bns454]

Ok,thanks for the input,its very helpful,I will work on those steps this weekend.

Accurate molds has a decent selection of molds including the 200 gr. paper patch we came up with for more like jacketed bullet velocities with a cast bullet that is paper wrapped.Robert

[runfiverun]

no problem.
if it's not clear or you have another question go ahead and ask until it is.
or PM me and I can clear things up for you.

NOE just started making a great 8mm mold!

[blixen]

Sounds like a great 8mm! I love shooting cast out of my Yugo Mauser, even though the bore is oversized.

You might want to slug your bore on the Rem., just in case.

[runfiverun]

NOE makes 2 good 8mm molds.
one is about 140 grs and I use it with 45/45 lube for plinking stuff in the 8mm.
but it sees about 9 times more use as a swaging core to make 38 sp swc's for bulls-eye type shooting, and as a core for making half jacketed RNfp bullets for the 357 lever gun.

More good input from you guys,Thanks !.I drilled out a piece of aluminum and poured in soft lead to make slugs for the barrel and to do a pound cast of the chamber.I have to work tomorrow and also get a driving rod to drive the slugs.Hopefully I will find time to start this project.Then the mould buying can begin.

For future reference you can also drill into a 2x4 for pound slugs. You just cut or chisel out around them.

[bns454]

Ok,thanks for the tip,I will try it out.

[swamp]

For driving the slug through the barrel DO NOT USE A WOOD DOWEL. I prefer to use a brass rod. Second is aluminum.

Or steel liberally wrapped with tape.

Here are the dimensions for the pound cast

[runfiverun]

your attachment is invalid you'll have to just type them out.
I can see the tapered section of the ball seat area, and how it funnels down into the barrel.
that boolit I showed has a tapered front drive band to mimic that transition angle where it changes from leade to barrel.
you need the nose engraving to guide everything when chambering the round, and to support it during acceleration. [it also starts the boolit spinning during the slowest part of acceleration making it harder for the boolit to skid]
the drive band will scuff into that ball seat area providing further alignment.
that's the easy measurement.

the bore diameter is for the nose diameter.

[runfiverun]

in the first pic I linked it shows 311 right there in front of the band.
I went with 313 because I'm also using the boolit in my 32 Winchester.
for a single purpose rifle 314 would provide a snug fit with engraving all the way around and good support.
313 would insures a slip fitment with [very light] light engraving and make the round more convenient to de-chamber in the field.
you can slightly adjust this fitment by manipulating your alloy with more antimony or more lead.

My favorite load of 12.3 grs. of Alliant Unique , with the IDEAL, 323471, sized to .325 ". The bullet has my own .014 " thick AL gas checks.

I couldn't be happier with my rifle.

I fired the 1st 5 rounds in the group below :

Then Jason shot a group with 8 rounds :

There aren't a whole lot of rifles I "crave" any more, but a purpose-built sporter in 8 x 57 is one such critter. A Rem 700 Classic would be a real coup for me, as would a Steyr-Mannlicher so chambered. The rationale is for easy scope mounting on a caliber I REALLY like.

I have two Lee moulds in 8mm that both shoot well in my current 8 x 57, a Mannlicher G98/40. The mainstream Lee 175 grainer has been my primary bullet, and 16.0-18.0 grains of Alliant 2400 was a common campaigner at Buckshot's old Burrito Shoots. If those rascals I shot with had a real bad day--and I had a real good day--I could actually win once in a while using this rifle and load. I set the barley-corn system at 400 yards, and the lighter load went point-of-aim = point-of-impact at 50 yards. The heavier load performed similar magic at 100 yards without sight change.

The other 8mm mould on hand is a 236 grain monster from a Lee group buy some years back. This one LOVES being driven hard, and when the bullet is happiest is about the same time I'm going "NO MAS". I haven't clocked them yet, but I have zero doubt that even at moderate velocities it could transit end-to-end through a mastodon. The steel buttplate on the G98/40 enhances the push-back effects comprehensively, too.

[bns454]

Nice shooting guys,I dream of groups like those.I have wanted a 8x57 that wasnt shot out or bent for over 20 years,I took the step and bought a good one.Wish me luck,but there are good coaches here.

[paul edward]

You can use 00 buckshot. At .33" it will be the right diameter and it is soft.

I just bought this NOE 325-216-SP mould during NOE's last big sale.

I haven't got to use it yet due to the usual summer travels and road trips, but hopefully this fall I'll get to break it in. I'll use it in my Mausers, but it should work a treat in that Remington 700 of yours.

[bns454]

Beautiful looking mould !

[GWM]

I just bought this NOE 325-216-SP mould during NOE's last big sale.

I have that one too. It is a very nice boolit :bigsmyl2:

I actually bought this one during the sale, in the .325", HP version.

But I haven't tried it as I haven't got it yet.
