Home Forums Hunting & Shooting Express Rifles and Big Bores Only Load data for 286 grain 9.3X62 Norma Oryx

Metricman,
I could write a book on the subject and would have to illistrate it to show the group patterns and what they tell you..or you could send me a group with the shots numbered with a diagram of the group and I can tell you what you need to do as for as inletting goes. I have kept these records for years and their is a definatel pattern to follow..

An example is if shots 1,2,3 (no. 4 goes high)and 5 are in a group going clockwise, then shot no. 4 went high because the tang area is bedded too low and you can bet the first shot will be center....If shot no. 4 was low in the same group then the action is bowed by the tension on the front action screw, and it may or may not mean the bedding is too deep in that area.

If you have a group you want analized send me an email and I will try and help you out within reson...I say within reason because the accuracy of the barrel is a major factor, so I can only analize a group from a good barrel I suspect.

Thanks Ray,
I don't have a particular rifle in mind at the moment but I was just hoping you could find a way to pass along the wisdom you have gained over the years. Perhaps at some point you will have the time and energy to do so.

Hi Folks -

In the intervening months since my last post on the topic of loads for the 9.3X62 I have stumbled across the "Quickload" software, and in playing with it and my CZ550 FS have discovered that the farther out I seat my bullets, the more powder I can get in the case without necessarily changing pressure. (This is probably obvious to all of you, but I'm pretty green). The CZ seems to have a loooong throat, and it appears I'll run out of magazine room before I get anywhere near the lands. This got me to wondering at what point will neck tension alone fail to grip the bullet sufficiently to allow adequate pressure to build? Current seating depth appears to be .469 for the .366 250 grain Accubond. Quickload says I can get 60 grains of RL15 in there and have a case thats 98.7% full, yielding 54,370 psi (56,565psi max, Piezo CIP method, whatever that means).

As a sanity check of sorts, Quickload says the 58.5 gr RL15 that Nosler lists as their max load for the 286 grn partition is over max when loaded to COAL 3.291.

So question number 2 relates to whether others have experience with Quickload for 9.3X62 load development, and whether this experience is good....

Thanks!

I use reloading data as a guide line,once determined to be factual.I then follow what MY gun,the one in my hand tells me what it will and won't do.
As a side note,my CZ 9.3x62 has long throat as well,once the hunting load was worked up, I set OAL for reliable feeding...

Genehunter,

Though a lot of people regard QuickLoad as the final word on any handload, it is only a computer prediction. In fact the disclaimer on the QL program itself (if you read the fine print) suggests using ACTUAL data from manuals if available, rather than depending only on QL.

In other words, don't put too much faith in QL for your 9.3x62, especially with the long throat in the CZ's (all that I have ever fired or heard about have the same throat).

Simply another tool, and can be a useful one, but no more than a tool.

Both RL15 and Big Game gave good accuracy in my 550FS 9.3X62. Big Game had the highest velocity, but I went with the RL15 load because I had plenty and use it in two other cartridges.

Thanks! What sort of velocities are you generating?

Cheers!

Right, thanks! I presume out of the 20.5 inch tube on the 550FS velocities would be ~150 fps less or so with comparable loads?

With 286 gr. Partitions and Hornady IL's I get 2300 fps with 57.5 gr. of RL15 and just over 2400 with 62 gr. of Big Game.
Both loads are with PRVI brass and Winchester LR primers.

Thanks husqvarna...I'm generating numbers that are close to this out of my FS with the same loads/powders using Lapua brass and WLR primers...
