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

I am constantly amazed at the accuracy of the 9.3x62. Has anyone had one that doesn't shoot? For a large game round I certainly go into the bush with confidence.

Sighting in a new scope, here is the final two shot group with 285 Lapua Mega projectiles over 58 of Varget. (Disregard the top composite group) Barrel is a Lothar Walther, scope was an FXII 2.5x20 with FCH @ 100 yards.

What primer?

Has anyone tried the 9.3 in a Sako Black Bear or a CZ 550 Carbine? Both have 20-21 inch barrels. Just checking and attempting to revive the thread.

Here's one that don't shoot. Whatever, it's still going to RSA on 5 June. It actually does better with 60.5 gr of varget

I just bought a CZ 550 Medium FS 9.3. I have brass, dies and Accubonds on the way. With any luck, I'll have some results to talk about this weekend.

Tophet and Ed, nice shooting. Damn I love this old cartridge.

68gr of RL-17 and a 286gr Hornaday gets 2515 fps in my 9.3x66, just sayin'.

bigwhoop,

I had a CZ 550 with the full-length stock and 21" barrel for a while, and spent part of one range session comparing the velocities of several loads from it and my CZ 550 rifle with 23.6" barrel. As I recall, the biggest difference in velocity between the two was 88 fps, with most loads less than 50 fps. One load actually averaged slightly faster from the shorter barrel.

Brad,
What is the accuracy like with that load? Any pressure signs?

Thanks Mule Deer. There is a CZ carbine in kevlar with open sights here locally that looks pretty darn nice. I don't think that is a new model but have not seen that configuration. The shorter barrel looks it'd be handy in tight quarters.

Doing a ladder with said bullet and powder. 68gr (2515 fps) delivered an inch @100m. Took it up to 70gr in 1/2 gr increments. 70gr is just under 2600fps. As I went up the accuracy widened. No traditional pressure signs at all up to 70gr. 2515fps ( 15' from the muzzle) duplicates a factory load in a 2" shorter barrel that I have. The 68gr load feels nice to shoot , 70gr you are starting to feel it.

Whats your point of impact difference between the 250 gr loads and the 286 gr loads? Mine was great till I switched stocks with a wood stock the load POI was 2" higher with the 250 gr load.
In a Mcmillion Edge free floated 5 " difference. Going to try a pressure point neutral to see I can get similar POI.

POI is approx 3" difference at 100m. I would normally sight the 286gr 3" high and the 250gr NAB's 2.5" high.
With the 250gr sight in the 286's fall 3" and to the left 2".

I have the CZ carbine with the 20.5" barrel. I'll be fine tuning two loads on Saturday and I'll post my results.

Btw, very happy with the little CZ!

Had my CZ 550 FS out yesterday. Normally I use 65 g. of Big Game with Speer 270 g., PRIVI 285 g., and Hornady 286 g. loads and all normally get close to 2400 fps in my 20.5" barrel.

After reading Mule Deer's comments on powders in his new book (he went to 66 g. of Big Game with 286 g. bullets); I decided to go up in powder with the Speer 270 g. Went in 1/2 g. increments to 67 g. With 67 g. of powder the chronograph just barely reached 2500 fps. Load seemed safe in my rifle. Will test it more for accuracy.

My rifle seems to like the Speer 270 g. bullets and Yukoner says they work very well in his considerable experience with the 9.3X62.

Furprik, How is your rifle bedded and barrel contour?

Mine is a fairly light contour, and POI changed when I changed stocks.

the rifle is a stock sako M-85

The 60.5g of Varget/250 Accubond is running 2550fps out of my 20.5" CZ. Impacts were touching on my 100 yd paper. I would say this load is a winner in my CZ Carbine.

Trevor, that about matches what I'm getting. My 20.5 Model 70 gets 2520 with that load.
