9.3x62 'plans' in motion

Those are all good loads using the PRVI bullet Johnn and Dgradinaru, very nice groups !
My CZ seems to have a very long throat as my COAL with the PRVI bullet is 3.410 " just off the lands.
Fortunately my magazine well is 3.50 " long.
I found a few boxes of 270 gr. Speer bullets last year so now I'm going to try to find a compatible powder to load under them..
Any suggestions humbly accepted..

Probably the guy to pose that question to would be someone like Ted. I'm just at the beginners steps concerning reloads for this calibre. Just glancing at the Speer manual, the powders I have that they have listed are IMR 4350, IMR 4064 and IMR 4831. If I was going to try some 270gr bullets, I'd probably go with one that's worked well for me with the 285gr Prvi bullets, IMR 4064. While with different bullet weights, Boomer's been using H-414 and Ted has used IMR 4895. Not much help am I:redface:. One consulation however, from what I've been told by a few, just about anything you put through it works well.
 
You're right Johnn, the 9.3 cartridge seems to work well with several combinations of powders and bullets.
My CZ is the second 9.3 that I've played with that shot very well from the 'get go '.

With my 9.3X62(which has now gone to another home in the frozen north), i got my best velocities and accuracy with a warmish load of Varget. My second choice was RL15.

This target demonstrates the differences between Varget and RL15. Oal, brass, bullets and primers were the same in all rounds.

:)You've got my curiosity up now. How do the results stack up against what you've obtained with other powders? Also, what prompted or stimulated your efforts with H-414?

In all honesty H-414 one of the powders I have lots of. But when I began work with the .366 Wagner, it was with 270 gr Speers so I went with the faster H-335, and figured that I might benefit from a slower powder once I got into the heavier bullets. For the caliber, the case capacity is small, which is why I've stuck to the ball powders so I could benefit from their high loading density. But with bullets lighter than 285, you can't get enough H-414 into the case for top performance. Even 285s are compressed, and as a rule I dislike compressed loads. But its better by just enough that I'll put up with it.

I got 2624 fps with 59.5 grs of H-335 under a 250 gr AB, but there was an extractor mark on the case head at 60.0. My top load with the 270 gr Speer was 58.0 grs of H-335 for 2500. At the other end of the scale with a Norma 325s over 63.5 grs of H-414 I got 2293, and while 64.0 grs gave me 2324, again I had pressure signs on the brass. I'm not sure what made me think of it, but I tried VV N-550 and got up to 66.0 grs under the 325, without pressure signs, and a velocity of 2467! I haven't used it for lighter bullets, and the limited case capacity might become a problem, but the idea is interesting.

Edited to add . . .
My 270 gr Speer OAL is 3.280".

MANY THANKS to all who are sharing their load data! Lots of good ideas here, more than enough to keep me busy at the bench..........

Now, you're talkin' ! :)

Bet those are a mittful in that "little" Husqvarna.

Be careful using loads like that in '06 cases, though. The earth will slow down in its orbit, and dogs will no longer bark.

It jumped around a mite. Sorry for the typo, the velocity should have read 2293 for the 63.5 gr load. You must be right about the earth slowing down, the days seem to be getting longer.
 
Boomer;
Thanks for your insight and info. Much appreciated. That's along somewhat similar lines as to why I went with IMR 4320 & IMR 4064, particularly 4320. Checking the Barnes and Nosler manuals, those powders were what I had in stock and were listed in their data. A small attempt to keep my variety of powders to a manageable number. That logic may fall by the wayside if I pick up some Speer 270gr to 'play with'. However, in the Speer manual a couple of additional powders they have listed like IMR 4350 & IMR 4831 I also have on hand.

Ted;
I appreciate your ;)words of caution concerning the use of '06 cases. Sounds as though they could cause more earth problems than global warmingLaugh2. I picked up the Lapua brass from Lefty 338-06 at the gun show in Duncan so I'm good to go for a while. Just wondering, I see Marshall at Matrix has a 250gr, 270gr and a 290gr listed. Have you tried them and if so, any info on loads and performance you could post or PM to me? I'll have to contact him and get a selection to try out.
 
I have been shooting some 325 gr bullets in a light Husqvarna using reformed 30-06 brass, the same as Boomer. He is much more a man than me, my 325 gr loads being quite wimpy at a mere 2250 fps.

The 270 Matrix bonded core was the bullet used on that big grizzly a few years ago. It retained over 91% of its original weight.

Broke the near shoulder, chopped up two vertebrae, and was found in the far shoulder.

Now use the standard flat base now, rather than the rebated boat tail that I was using that day.This is pretty typical expansion. Every Matrix Bonded I have recovered, five, has retained more than 90% original weight.

Heading out for a day hunt for bison on Friday, so went and checked the sighting of the pre64 Model 70 this afternoon. The ammo and rifle both were at -15C for half an hour before firing:

270 Matrix flat base, 61 gr Re15, and WLRM primer, got 2570 fps out of a 20" barrel.

Ted
 
Thanks for all the details Ted.:) Much appreciated. The mushrooming and weight retention of those Matrix bullets, impressive to say the least. ;)Looks like I'll be definately making contact and arrangements with Marshall before too much longer. Thanks again, take care and good luck Friday on the Bison hunt. That's on my 'bucket list' to try one day.

Ya right. Post the pic again of you pulling that bear along the river bank. The only way I could have moved that bear is by paying another bear to pull it, never mind getting it in the sleigh. Or perhaps post the pics of you packing the moose down the side of the mountain; mountain hiking pretty much killed me and I had no moose to carry. I'd have just moved my camp to the carcass and stayed there till the moose was eaten up.:redface:

I'm waiting patiently to see photos of 'details' of the Bison hunt. More typical Ted 'activity' photos I'm thinking.
