looking for 9.3x62 reloading info

[burnt_servo]

looking for some reloading "recommendations " . I have a rough idea of what I might be doing , but I'm pretty sure someone out there has already done what I'm thinking of , so instead of reinventing the wheel I thought I'd ask first

for bullets , this is what I have

232 grain norma Oryx

250 grain nosler accubond ( this is the one I want to use hunting this year . )

285 grain privy

285 grain gaschecked cast

for powder I have

imr 4831

h414 , w760

primers , remington 9 1/2 mag

cases are privy 9.3x62 cases and older Winchester 30-06 cases fire formed .

and to throw a monkey wrench into things , the chamber is a improved chamber and fireformed privy brass holds a average of 9% more volume than factory privy cases ( just a hair over 73 grains of water to just a hair under 80 grains of water volume )

the throat is also cut longer than standard , and it is on a husky 1600 action .

I'm thinking that a top end load for a standard case might be a mid , or even a starting load for the improved case .

with the 250 grain accubond I can seat it out to 3.48" before I run into possible issues with not enough neck to bullet contact .
if I find some 35 Whelan brass with a longer neck , I can seat the same bullet out to 3.55"

so anyone have any ideas ?

While I cannot answer your question.... There's a fellow on here who has done more work for load development and testing in this calibre than perhaps anybody else. His forum name is "Why Not?"

Here's a good link... http://www.canadiangunnutz.com/forum/showthread.php/1103562-9-3X62-loads-for-the-guys-who-want-to-get-beat-up!?highlight=Beat

I'm away from my reference books - how does your case volume compare to 9.3x74?

 

[9.3mauser]

Most of my load work has been done with RL 15; now virtually impossible to obtain so I'm going to have to start over again at some point, but for what it's worth...

62 grs. 250 Accubond 2625 fps.
58.5 grs. 285 gr Nosler or Woodleigh, 2415 fps.

this is with a standard chamber, & long husky throat. Neither of those loads are max, but I'm comfortable with where they are.

 

[spooksar]

I use 61gr of Reloader 15 and 250 Accubonds I've shoot 20 plains game with this load works fine

I'm away from my reference books - how does your case volume compare to 9.3x74?

I had to look this up .

according to barnes #2 reloading manual , 0.3x62 is 74 grains , 9.3x74 is 84 grains of water . I ran across some posts in another forum and one mentions his cases are averaging 82 grains of water .


while comparing numbers I ran into what could be an anomaly . in the barnes manual , the load info for the 74 case was within a grain for the same load info on the 62 case .

following this line of reasoning powders listed for the 74 case , but not for the 62 case , should work in the 62 case .

this seems to have some legs on it with other reloading manuals , but actual reloading info is all over the place for both rounds . so trying to estimate powder charges is difficult .

so what I am thinking is this ,

with the 250 grain accubond ,

h414 / w760 top load , around 67 grains , possibly as high as 70

imr 4831 around 65 grains , possibly as high as much powder that can be put into the case and still able to seat the bullet

for 285 / 286 bullets ,

h414/ w760 , 60 - 65 grains , top load

imr 4831 65 - to as much as can be put into the case and seat the bullet




thanks for the help guys

You'll get better results with faster burning powders, like RL15, H-380, Varget, IMR 4064, IMR-H 4895. IMR 3031 or H335...

As for the throat lenght, all my rifles in that caliber (about 7) have long throats, even those recently manufactured.

 

[BigUglyMan]

Ted should be along here shortly to add his two cents. Baribal nailed it with the powder selections. I use RL15 in mine but N550 or RL17 will up the oomph. Varget should behave nicely too.

 

[burnt_servo]

just out of curiosity , I can fill the case with 75 grains of w760 and seat a bullet ( either a 250 accubond or a 286 privy) .

with imr 4831 I can fill a case with 70 grains .

I have a lot of experience with heavy compressed loads with 4831 , but this is the first time with loading with 760 . does it like to be compressed ?


on hodgdons burn rate chart ( https://www.hodgdon.com/burn-rate.html )
n550 is almost as slow as imr4831 , and r17 is a bit slower than w760 , so I'm probably not too far off .

 

[Mauser98]

I'm curious as to how the case was improved. Shoulder angle steepened and/or moved foreward? Case sides blown out? Curious minds!!

 

[burnt_servo]

if I can find the reamer print i'll post it . 40 degree shoulder , shoulder diameter around .460 . neck lengthened about 60 thou so over all length of case is 2.5" .

not huge changes , but it started off with preventing hot handloads from making their way into 96 action rifles .

factory rounds can still be safely fired .

[jethunter]

i'm away from my data books and records, but W760 worked well for me using 270 gr Speer bullets. Don't remember the powder charge weight.

 

[Why not?]

I am away for several more days, and have only a few loads in my head, however we already have one thread on here with plenty of loads.

[burnt_servo]

just a thought , after hours of reading the thought occurred to me , is it possible to put enough h414 / w760 behind a 250 accubond to even create any sort of pressure sign ?

I made up a bunch of test loads going from 60 grains up to 73 grains of w760 with the accubond bullet . i'll probally head out tomorrow to light them off .

 

[jethunter]

You would like the software program "Quickload". It could answer some of your questions without you having to fire a shot. Quickload is not the final answer to developing a load but it sure can get you in the ballpark quickly. Everyone i talked to told me W760 was too slow to be a good 9.3x62 powder when i was looking for x62 loads. But Quickload said W760 would be good, and it was.

 

[burnt_servo]

I was looking at quickload , they want 150.00 for it .... I'm going to see if I can find a cracked version to play with first , then it I like it actually buy it .

 

[burnt_servo]

went out today and played with my rifle .

went from 60 grains up to 73 grains of w760 with a 250 grain accubond , loaded to a aol of 3.470" .

at 70 grains the primers started to flatten , at 71 grains it started kick and bark a bit louder , then at 72 grains I finally got something to measure on the case head , several cases averaged 5 ten thousands of an inch increase in diameter .
73 grains was similar to 72 grains but the average case head expansion was almost 8 ten thousands of an inch .
