Help PP a 9.3x62mm

[no34570]

Hi
I have a 9.3x62mm and I want to PP it,now I slugged the bore and got the groove dia(.3675-.368) and the bore is around the .355-.356 or even .357.
Now what I want to know is,should I go bigger in a PP boolit?,how much bigger?
I was thinking of just getting some .358 moulds( I have a few,for my .356Winchester)and using them as PP boolits,what you all think? Too big?

Any ideas? on what to do here

Thanks in advance.

That's one of the nice things about a 9.3 - you use normal 35 caliber boolits in it. If you have a heavy 35, say 250 grains and up, you are in business. You can try 200s in it, but they're pretty short and likely won't shoot as well as the bigger ones.

Thanks for that,I have only 200gr RCBS Clone from NOE and a few 150-158gr moulds for when I had a .357 Mag in a GP-100 Ruger.
So if I got a couple of .358 size moulds,you think size them down to .355,.356 ??????

For my Ruger 9.3x74R I cast a 245 gr. 0.358" Saeco bullet and patch it with tracing paper. No sizing before or after patching is needed.

Thanks Reverend Recoil,might get some big .358 moulds ,)

[Nobade]

Yep, 9.3's bore is supposed to be .358 so no sizing needed.

I've been looking for a decent mould for my 9.3x62

What is the minimum/maximum weights anyone has found to work?

How do they shoot???

[pdawg_shooter]

I always get better accuracy with heavy for caliber bullets. That and a powder that will give me near 100% load density works for me anyway.

[Reverend Recoil]

In my Ruger 9.3x74R, my paper patched bullets shoot as well as any of the Speer, Hornady, Barns, and Prvi Partizan bullets I have tried.

At the shooting club somebody always asks, "What is that white stuff on your bullets?"

Hi pdawg _shooter
So you think I should go for heavier bullets,like say from Accurate Molds,he makes PP any diameter you want and he has one there a 310 gr one,the 36-310P,looks like a goer:)

Hi RR
What moulds are you using?,what are the weights?

Well that is something to look forward to,for when I start,thank you

[Reverend Recoil]

The mold I am using for my Ruger 9.3x74R is a Saeco 2-Cavity Bullet Mold #352 35 Caliber (358 Diameter) 245 Grain Flat Nose Gas Check.

Hey RR
Your images don't work ;)

[9.3X62AL]

The 9.3mm bore traditionally used a 3 turns/meter twist (about 1 turn in 13.1") to service 232 to 286 grain bullets. Newer (2004-2005) CZ-550s use 4 turns/meter twist (1-9.75") to service 320 grain bullets. In a sporter-weight rifle, a 300-320 grain bullet would smack the living daylights out of a shooter. The 286 grainers at 2400 FPS give a pretty good thump as it is.

My rifles rate of twist is 360mm(14.1),so 1-14.1,could I still go over 300gr boolits with this?
I have to agree,the 286gr load,does let you know when it has gone off :)

34570--

No real-world idea whether the longer bullets would fly true or not in the slower twist. I haven't tried any such tricks in my rifle. Those Woodleigh and other such custom bullets are a mite expensive for plinking or random load testing.

My thoughts, after 9 years of great fun with this caliber--the Nosler 250 grain Ballistic Tip might be the single-best bullet available for the caliber. It is capable of similar ballistics to the 30-06 and its 180 grain bullet--trajectory is close to an exact overlay, and the bullet hits at any range with half again more energy.

Also--what is 320 grains at "x" velocity going to do better than 286 grains will do starting out at 2450 FPS? I think the mega-weight bullets are marketed at those who feel that "more" is always better than "less", reality notwithstanding. Even the lightest bullet offerred for the 9.3 x 62 in factory ammo--232 grains--is still a pretty hefty hunk of metal. I darn sure wouldn't want to stand downrange and try fielding them with a catcher's mitt.

I have to agree,I was just wondering what would stabilise in my rifle,with the twist I have. Went on google search for twist calculator and got one that told me with my twist,I can safely use a bullet with a max overall length of 1.440,did that with a few calculators that I found,all came back with the same 1.440 or if I put in for cast bullet at .368 it was 1.450,plenty of lee way to try them.

No,that could ruin your day mate:razz:,for sure.
Thanks for your wisdom and help,appreciated[smilie=s:

Sweeeeet!,that is some good looking pics and like the rifle,good sized pig,well done,I'm envious:-D

[Reverend Recoil]

Thanks. The scope is a new addition. It is a Leupold FX-II Ultralight Rifle Scope 2.5x 20mm Wide Duplex Reticle Matte with Control base and rings. I shot that boar on the run. With the 2.5x scope I was able to keep both eyes open to swing and point the rifle like a shotgun.

[303Guy]

But that is a beautiful cartridge. Cartridge and gun! The right combo I should think. Very healthy recoil without actually breaking your shoulder bone? A strong push , not a baseball bat blow? Great pictures, Thanks.

Like Reverend Recoil, I have a Ruger No 1 in 9.3X74R. I have had great luck pp ing the Lyman/NOE 358009. Tried it with and without a gc and make no difference.

[pdawg_shooter]

Hi pdawg _shooter
So you think I should go for heavier bullets,like say from Accurate Molds,he makes PP any diameter you want and he has one there a 310 gr one,the 36-310P,looks like a goer:)

I always have better luck with heavy bullets, IF the twist will stabilize them. I have had, and got rid of a number of smooth sided paper patch molds over the years. I prefer grooved bullets sized to bore diameter +.001/.0015. The grooves lock the patch on for the ride down the bore and hold a bit more lube. I use a 451114 almost exclusivity in all my 45s, and if I could find one, a 301618 or 301620 would be perfect for my 30s. Other wise, I cast from a standard mold, size down in a push through die and patch back up. Works for me anyway.

That is good to know. I had been wondering if the .350" 35 caliber bore riding nose would make it too loose in a 9.3. I guess it patches up so it is a bore rider in that size barrel too, with a bigger rear end to seal. Between that one and the boolit that Gearnasher designed to be a patched bore rider in 30 cal barrels it looks like that concept works well.

I have to admit,I was leaning towards going with smooth sides PP boolits,for that is what I tought was/is a PP boolit,but with what you and all the other fellas are saying,that you can get really good results from grooved boolits,that I will go with the grooved version,I will put my name down for the 358009 groupbuy,on this forum and maybe a few others. :)

I use my .303 British or 30/06 for my main hunting,now don't get me wrong,they are great calibres(I like the .303's)but I think if I utilised the 9.3 for all what I hunt,I could not go wrong?? And even maybe for a buff hunt up the Top end of Australia[smilie=w:,now that has me looking forward to trying different weights and loads.
Thank you to all that steered me onto the right track.
Cheers.

I too have always wondered if the nose PP was sufficient to support the nose, and not cause any cant or slump

[pdawg_shooter]

I run my patches to the start of the ogive. I am careful to be sure the bore riding section is at least bore diameter or .001 over.

I just jotted that bit of info down,thanks,I know it was tendered to be for nunuk,but! :)

[pdawg_shooter]

You are welcome to any info I might have, little as that may be.

[nanuk]

pdawg:
so you would suggest that the 358009 would not be your first choice in a .358/.366 barrel, cause the nose would not be "Bore diameter + 0.001-0.0015?

[pdawg_shooter]

Don't know that bullet. Easiest to get to shoot is a Loverin design. That said, my best bullet in 30cal is the 311284, with the nose section lapped out to .302. I size full length to .3015 and patch with 16# paper. The 311446, (a Loverin design) shoots good in MOST 30cal barrels. Sized .304 and patched up both work great in a 303 British.
