Home Forums Hunting & Shooting Ask The Gunwriters Mule Deer's 9.3x62 data

Sorry, but to avoid errors I trashed my S&B brass.....but the difference in capacity was surprising.....I like the Hornady brass.

I do use CFE223 in a .308 Winchester.....so can you say how much you use in the 9.3?

I wasn’t so interested in the S&B. I am using Lapua and I was wondering what the Hornady held.

I’ve been using 65.0 of CFE223 with a 215M behind the 250AB in Lapua brass. It yields 2625 out of a 20” barrel.
The load is warm in my rifle so normal cautionary approach is advised. It shows
exceptional accuracy and low SD. Quick load indicates it will yield highest velocity
of all powders given my parameters and seems to deliver such.

I'm new at this water measuring thing.....but have a substantial respect for quickload.....I just weighed a Hornady 9.3 X 62 fired case full of water.....the water weighs 74 grains.....

With that, can you tell me what a 200 grain bullet ahead of 63.0 grains of varget might have in velocity and what pressure it might generate.....I'd dearly appreciate it.

GS also makes a 195 9.3 bullet. Don’t know the price though.

The light weight .375 GS is reported to be an outstanding buff killer by one of the safari guides here. I imagine the 9.3 would be more of the same on near anything.

ETA- .366 195. they ain’t cheap either!

yousers....it makes me wonder what I'm not getting in the Barnes for a bit less than half the price.....

Happy to..... What is your barrel length?

4



24 inch

With a 210gr Raptor @ 3.291 OAL and 74gr capacity and 63.0gr of Varget, you should be in the neighborhood of 2815fps and 59k psi..... It shows to be 107% case capacity.

That's close to 3700 FT-LB energy.....and potential for more should one seek it.

Thank you....now to do some guessing as to BC and estimate trajectory....are we really allowed to have this much fun?.....LOL

I seems we have just turned the 9.3 X 62 into a mild recoiling plains game, elk, moose and even deer rifle and at the same time should one wish, he's ready for some serious confrontations with things that bite you....using heavier bullets of course. With the lighter bullet it carries almost 1500 ft-lb of energy to 400 yards. or so.......excellent!

For you with JES re-bore's, what twist and how many lands did you go with?

Three groove, 1/14 if I remember correctly. He will only do three grooves with the 9.3 as I recall. They shoot horribly however.....all the bullets go into one hole so I end up thinking my first shot was on and the rest are missing the target. It's horrible I say!

I finally tried some Ramshot big game in mine. 66 grains gave me 2,485 fps with ppu 285 grain bullet in my 22” barrel. Measured with magneto speed.

Just for interests sake:

I use, and have only used, Hornady brass for my 9.3 x 62. It has served me very well. No complaints -- except for a minor one. Occasionally, one of the new cases has a slight flange at the mouth where the brass was cut off. I discovered that early on in my reloading attempts. It would keep the case from going all the way into the chamber. Now, I just trim all new Hornady cases on principle. New cases never fired hold 76 grains water. Once fired and resized holds 77 grains water. I was also informed by an impeccable source, that came indirectly from Hornady, that their 9.3 x 62 cases were manufactured by S&B. Some have given me an argument over that since the carton containing the brass cases says "Made in the USA". That's not uncommon in some manufacturing these days. It states that on my boxes of Hornady brass as well. However, that was eight years ago and it's possible that matters have changed since then. There appears to be a significant distinction in the volume of certain brands of 9.3 x 62 brass -- it's important to know that when sharing information. As well, COL and primer brand, including whether the primer is "standard" or "magnum" is ALSO significant. Rifle make and barrel length come into play as well. Then, it would be helpful, and polite, to suggest what approximate pressure is being used. I have written reloading manuals on a few rifle cartridges, and ALL such information is critical. All of the following has previously been documented here and elsewhere: Rifle = TIKKA T3 Lite (RH) in 9.3 x 62. Weight with 3 - 9 x 40mm scope = 7.4 lbs (4 cartridges of 286gr = 7.7 lbs). Primer = WLRM. Brass = Hornady. COL = 3.37". Barrel length = 22.44" (570mm).

I have had excellent results from Hornady 9.3 x 62 cases regardless of who makes 'em. At pressures of 60,000 to 64,000 psi, I've reused them several times over without a problem. And then I reuse them again in developing lighter psi loads. However, as previously mentioned, I ONLY use new-unfired cases for hunting purposes. But sometimes once-fired cases get loaded for certain hunting applications where max loads aren't needed or wanted.

I just wanted to add some of my findings to this conversation. All of my data has been collected using a caldwell ballistic chronograph. I bought my Zastava M70 Left Hand 9.3x62 after my father got a CZ FS in the same. I love the capability of this round and the more I reload, I realize that it may be one of the best cartridge cases that uses this bolt face. I WORKED UP TO ALL OF THESE LOADS, PLEASE DO THE SAME!

Privi Partisan Brass 77.1gr H2O virgin brass 77.6gr H20 fired capacity
CCi 250 primer
65gr Ramshot BigGame
3.293" OAL
286gr Swift A-frame
2543fps -probably above maximum slight click on bolt lift

Privi Brass
CCi 200
65gr Ramshot BigGame
3.293" OAL
286gr Swift A-frame
2506fps- no bolt click and all holes touching -$$$- (I found that after 4-5 firings the primers were still tight but I needed to bump the shoulder back 0.002" to eliminate hard close and open of the bolt)

Privi brass
CCi 250
65gr Ramshot BigGame
3.300" OAL
270gr Speer
2523fps- within 1MOA POI from Swift groups and <1MOA precision

Privi brass
CCi 200
65gr Ramshot BigGame
3.293" OAL
285gr Norma Alaska
2473fps- very accurate bullet- my rifle really likes it.

As a note, I tried the Nosler Partition 286gr as well and it was not quite as accurate for me but hovered just around 1MOA with the 65gr Ramshot load

Here is where I did a lot of math and inferring- please work up loads to this level (I started at 64 grains)
CCi 250
285gr Norma Alaska Bullet
3.362" OAL (this leaves 0.326" bullet shank in the neck and increases case capacity 1.85gr versus 3.291" OAL")
68gr Reloder 17
2530fps - I took my largest deer ever with this load. He dropped in his tracks at a high shoulder shot 167yds.

I wanted to try the better BC 250 bullets so I got both barnes TTSX and Nosler Accubond
I noted that even at the highest powder charges the recoil was significantly less with 250 grain bullets

Privi brass 192.7gr wt
3.465" = maximum OAL to lands
Maximum magazine length 3.390"

250 Barnes TTSX
60.5gr Varget
Winchester LRP
2530fps very accurate low SD -much slower than expected
3.385" OAL

250 Barnes TTSX
65gr CFE223 - (I started at 61.5gr- 2524fps and worked up to 65.5- 2649fps all primers were round)
CCi 250
2629fps ES-10fps just over 1MOA


250 Barnes TTSX
65gr CFE223
WLR primer
2645fps ES-31fps just over 1MOA (2 touching 1 out)

250 Nosler accubond
65gr CFE 223
WLR primer
2620fps ES-12
2.765" CBTO (using 35 cal ogive die)


Going forward, I am going to have my stock bedded and will be working with the Alaska bullet and the Nosler Accubond bullet exclusively. I hope to hunt Elk or Mule Deer this fall with this rifle and its 3-9X40 VX-r scope. Sorry for the long post but I hope that people can draw info from my experiences.

I just got me some dies for Christmas .
I plan on using Big Game (maybe try hunter) as I have 8lbs of each. Will Loading with 250 accubonds.
I am planning on starting at 60 grains of BG and working .5 increments up to 64 gr.
Rifle is sauer 100.
My Question, Do the 250 accubonds or 9.3 like little jump or closer to lands or it just depends per rifle.
Thanks in advance

I have no experience with Hunter in my 9.3, but I would advise using Varget with 250s and saving the Big Game for 286s.

Call me boring, but several years ago when I had a 9.3X62 built, I wanted loads for 250s and 286s.

JBs 250 load was either RL15 or Varget for 2650 fps. With the Accubond his RL15 load went easily under MOA and ten shots averaged 2647 fps with tiny velocity spread in my rifle.

With 286 NPs, his 65-66 grains of Big Game for a supposed 2475 fps? In my rifle 66 grains clocks 2470 fps and shoots inside the 250 grain load. Better accuracy and same point of impact.

As far as seating depth, my rifle has a bullet diameter but longer European type throat so I couldn't measure off the lands like I normally do. So I simply seated them both to OALs typical for the 3.38" mag box.

Load development DONE.

Unless a guy loves chasing handloading minutiae for entertainment value, which I get, why complicate things?

thanks
I'm going to be using the powders I have for now. Im getting my start load data from this.
