I recently liberated a CZ550 American from the local gun shop. I'm finding very little load data for it. Can any one help me out. I want to put together a deer and pig load with the 270 grain speer. Because they are inexpensive and a deer does not take a super premium bullet in this caliber to kill it. The other load will be for big horned and toothy critters. I was thinking a 286 Partition or TSX. I wanted to use the heavy load on bison in December. If any one can share some of their experiences with me I would appreciate it.

You might check Speer's website, I'm not sure if they list loads or not. Some of the other online powder companies such as Hodgen's also have online data. My Speer manual list a starting load of 60 grains of IMR 4831 and a top load of 64 grains behind the 270 grain grand slam. If you tell me which of these powders you want to use I'll give you what Loads are in my Speer manual for that powder. H414, 760, IMR 4350, H380, IMR 4064, IMR 4895, 748.


I've often thought about one of CZ's full stock rifles in that caliber. It would be a dandy elk rifle here in Idaho.

I believe the Nosler manual has data for that cartridge, as well as Speer.

You might check out these articles at Realguns.com:

The CZ 550 FS, Part I - http://www.realguns.com/archives/152.htm
The CZ 550 FS, Part II - http://www.realguns.com/archives/153.htm
9.3x62 Load Data - http://www.realguns.com/loads/93x62mm.htm

This is a 3 part series on the 550 FS in 9.3x62. I would consider his loads MAX, and load down 10% to start [you know, standard disclaimer ]

I have IMR4350, IMR4895, and H414 on hand.

Check out Hodgdons.

Nice group. What has your field experience been with your 550? I'm counting down the days till early October when mine will be going to look for elk.(I feel bad. I was originally going to take my Remington 700 classic in 8x57js) I may even take a doe in our early season with it just for fun. What other loads have you tried or had good results with?

I haven't tried all that many powders. I tried R-15, H4895 and Ramshot BigGame. All three of these powders performed about the same out of My CZ as far as accuracy goes. BigGame took top honors in accuracy and velocity.

Here is a target at 100 yards. The group on the left is five (5) rounds, 65gr Ramshot BigGame, 270gr Speer, Lapua brass, WLR primer. The group in the right is 65gr BigGame, 286gr Nosler Partition, Lapua brass, WLR primer.


My field experience is limited. I have only taken three whitetail bucks so far. They ranged from about 75 yards to 160 yards. All three DRT and meat damage was minimal. They were all shot with 286 Partitions.

Steve,

Not trying to hijack the thread, but last year I passed on a Remington 700 Classic in 8 X 57 and just want to know how you like yours, on a scale of 1 to 10, and how accurate is it.

Thanks, JJ.

Well I made it out to the range today with my starting loads for the 9.3x62 and 8x57js.
Both rifles shot well. My starting load for the 9.3 was 60gr IMR 4350 with a 270gr speer hot cor. Once zeroed in I was able to shoot a 1 3/4 in group at 100 yards. I'm hoping to see it tighten up a bit as velocity increases. Going to load ten up with 61gr IMR 4350 and see how they do.
I may pick up a pound of the Ramshot Big Game to try also. Also considering Reloader 15.
I'm sure curious to see how it does on Bison this December.

I love my Classic. So far I have only worked up a second load with 200 gr Acubonds. Velocity is hovering arround the 2600fps mark. I have two more grains for IMR 4350 to go till I'm at max load according to my data from Nozler. Seems to be very accurate. One hole groups at 50 yards and 1 to 1 1/2 at 100. I'm shooting with the scope set on 4x.
I think you missed out. The one I picked up was on the shelf for quite a while and I was able to get it for a steal. It's one of the nicest looking guns I have. My gun smith has bedded the action and free floated the barrel, done a trigger job and lapped the lugs. It is butter smooth. This is my deer and pig gun.
On a scale of 1 to 10. I say a ten.
I originally bought it to turn into a 338-06. My gun smith refused to change it. It's barking on the heals of the 338-06 with less powder.

You really know how to hurt a guy. Once upon a time I had a Parker-Hale 1200 Super in 8 X 57 but let it get away. I was going to replace it with the 700 Classic 8 X 57 but also let it get away. All's not lost however, because I used the funds to buy the new BLR Lightweight in .358 Winchester.

Thanks for the info on your 8 X 57.

Send me a PM if you want more loads. Never actually had a 9.3x62, but I was collecting loads on the chance I'd get one someday.
