Which one is brute tougher @ around 2700 fps muzzle velocity .....Thank You ...

The Oryx bullet is much tougher...I have used it in .338 (230 gr.) on red deer and wild boar and never recovered a bullet ! Excellent bullet and very accurate also...

325 grains Oryx would be the better bullet,

not by much, but still.

Best regards Chris

I already have the 285 gr bullets ... I have known about the Lapua Mega bullets performance on brown bear from the 9.3x62 Mauser , but was wondering if it would hold up to the much higher velocity of the 9.3x64 B ..

Thanks for the replies ..

Gumboot, I'm a bit sceptical whether you can safely get 2700 fps out of a 9,3x64 with a 286 grs bullet. But be that what it may, here is a link to a pdf file (you need Adobe Reader to read this) which presents the findings of a Swedish 9.3mm bullet test.

You may not be able to read the text (assuming you don't read Swedish?), but you should be able to understand the data tables which list numbers for penetration, retained weight, expansion diameter etc - at different impact velocities.

I have personally found the Oryx bullets to expand quite a bit. But I have not used them in .366" cal.

MHO ,, I was Way skeptical of it also , But I found Saeed had tried IMR 4350 in the 9.3x64 B and BW had some data on the 416 Taylor web page showing IMR 4350 . I had some and tried it .. I started @72 gr of 4350 with the moly tumbled 285 gr Lapua Mega bullet , it seemed fine so I loaded some up 1 grain increments to 77 grains .. 77 gr was hot but then oddly enough so was the weather .. 80 degrees F. in the shade .. 75 grains was what I settled on .... I have started bringing my reloading travel kit to the range and I stayed with the same 6 brass and just kept reloading them ... I need to do more testing but 74 gr gave me 2640 fps .so If I think 75 gr is too hot I can easily back down 1 gr. I have 4 reloadings with the 75 gr IMR 4350 and 285 gr Lapua Mega and Norma Orynx bullets so far and no case failures yet .......

I sure had poor results with RL 15 WAY too hot @ 65 grains .... WAY TOO HOT < BLOWN PRIMERS> Thank you for the link .... I also loaded 75 gr ov RL 22 . Didn,t chronograph that one yet , but will ..... 21 .5" barrel by the way ..

You need to be careful using RL15. I've found extreme performance differences using different lots (same true of RL19 and RL22) ----

Worse case was with my .375-cal Lazzeroni Hellcat.

The 1st loads I tried gave me 2550 fps (300gr Nosler) with no signs of pressure. Like you I like to use the same pieces of brass over and over while testing as I like the idea of checking for pressure with loose primer pockets and the load I used did not loosed primer pockets with each being fired 8 times.

The next lot of RL15 I bought I backed off the load 2 grains (to be sure I thought) and the 1st load I fired produced significantly more recoil, almost 100 fps less velocity and I had to bang the bolt-handle with the palm of my hand to eject the case --- the case-head was heavily marked..... all loads had been weighed and checked twice, same lot of primers, all measurements checked twice ---- I pulled the rest of the loads and they were all correct.

I then searched all the local stores to see if I could find the same lot as the original and when I did the performance was exactly as the 1st lot --- 2550 fps with no signs of pressure.

You might try Varget for similar performance without the lot-to-lot variation which is not my powder of choice in the .375.

DB , thanks for the heads up ...There have been times in the past when I thot RL 15 acted too fast or too slow I found it varied quite a bit in the 416 Rem mag .. In alot of ways it is The 416 Rem powder . Some guys can get 2500 fps with a 400 gr bullet with it but some the next time they buy that powder they stick the bolt and can,t even get 2400 fps , ...

Hello

You should never use the 286 Mega in 9,3*64.
This bullet is made for 9,3*57 and 9,3*62, and has typically 70-80% weight when found inside a scandinavian moose.
I tried the 286 Oryx in Namibia recently, and came to the conclusion that this bullet is equally soft as the 286 Woodleigh RN. That means too soft for the speed of the '64..
At 2300-2400 f/s it works wonderfully.

.. This is sad news as they really fly out of my 64 ..... Thank you .. I think I will do a water jug test ...

Partitions and Swifts are twice the bullet, and they work at the 9.3x64 speeds.
