9.3X62 Loads - 285 gr PRVI - Three Different Powders

[Andy]

M98 Action, 1:13 twist 26" Barrel

285 gr PRVI, 3.300" OAL

Swedish Metallverken Brass - thick!

1. RL17 - 64.0 grs (full) - 2485 fps
2. H4350 - 64.0 grs (full) - 2400 fps

Reformed WCC 55 30-06 Military Brass

1. RL17 - 67.0 grs (compressed) - 2610 fps Ouch!
2. H4350 - 67.0 grs (compressed) - 2500 fps
3. Superformance - 71.0 grs (compressed) - 2500 fps

In rough order of Burn Rate - confirms again that RL17 is faster than H4350. Loads in RED are considered Max @ ~60K psi. I'll drop the charge by at least one (1) gr.

More people should try Superformance. It's available, relatively inexpensive and a good performer. People shy away because few loads are published. It's a high density Ball Powder with a Burn Rate between H4350 and H4831.

Once I tried Ramshot Big Game, I stopped looking. Hard to source I know.

66 grains clocks 2475 fps with the 286NP, and has the identical POI on a 100 and 200 yard target as a 250 grainer at 2650 fps (62 RL15). Both in Lapua brass with CCI250s.

Those loads were shamelessly stolen from John Barsness. He had them pressure tested and they do not exceed 60,000 psi (30-06 level pressures).

Which one did you find the most accurate? That RL17 load was the ticket in the '98 I got from you....I just finished lowering the cheekpiece and fitting a new recoil pad, installed a Dayton safety
... first time using one of those, install went ok, but you can open the action with the safety on with this design, which is good and bad, will see if I like it in the field, can always drop a timney in later.
Still have to detail finish it but looking good so far.

Two few shots taken to really know, but I need to bed the action.

P.S. the Lee 9mm Makarov F/L Die makes an excellent 9.3X62 Neck-Sizer.

 

[saskgunowner101]

That's some impressive performance with RL-17!

 

[medvedqc]

impressive speed. i do not know how the bullet will handle the impact ...

 

[BigUglyMan]

That's moving right along. I'm with Phil...I wonder how much impact that bullet can take. A Partition would make me much happier if I was squeezing 150 FPS extra out of the old Wagner.

shipping starts back for the big game powder from Belgium ( the plant exploded then NATO was using a lot of the powders made there) for our southern neighbours so we may got the surplus next year ....

PRVI is holding better than partition so far .... and i really like the partition in 9.3s and 375 ....

1. RL17 - 67.0 grs (compressed) - 2610 fps Ouch!

Now, that is smokin' Andy, and must recoil more than the 325s heading out at over 2300.

Even though the 9.3X62 doesn't need that much velocity to perform very well on really big game, I am quite interested in how a single case will hold up to five or six repeated loadings of that, if you are so inclined.

You probably meant an extra 150 FPS, and it would be crazy in this "little" angel.

A svelte 7 1/2 pounds as you see it.

My neighbour was shooting it yesterday with 285 Lapua Megas at a lazy 2240, and says that is plenty for him. It is enough for me, too. That velocity is 90 fps faster than the original 1905 factory loading, which established its reputation on everything that walks in Africa. Imagine what over 2600 fps would feel like!

Any of the loads posted in this thread will be more than enough for big game in NA.

Fast for sure, but folks are free to load down as preferred. 2610 fps is from a 26" barrel, so that probably accounts for 50 fps or so faster over barrel lengths used by most. I used a lot of sanity checks along the way in developing that load, including this table from Handloader Magazine. Ramshot Big Game is faster than RL17, so while I'd consider 67.0 grs of RL17 a Max, it's not overly so.

As stated:

As for brass life, I have a bucket of 30-06 brass so if I only get five, or four firings, I'm not too concerned. That said, I usually drop loads that won't provide at least five firings and tight pockets. In this now twice-fired brass (once a long time ago as a 30-06, and then yesterday as a 9.3X62) it's still good and tight. We'll see.

 

[Why not?]

Some of my CIL-Dominion '06 formed brass has lasted several dozen loadings using 270s at 2500fps and 2856s at 2300+ fps, with 4064, 4895, Re15, etc.

Primer pockets are still tight, anneal the brass every five or six loads, and have been using those same cases so long have actually lost count.

Ted

 

[RickF]

It will be interesting to see how long my primer pockets stay tight. My velocities are within 20 fps of Barsness' so pressures should be about identical as well.

And in the "for what it's worth" category, my rifle weighs 7 pounds 6 oz scoped but empty. I have zero interest in trying any load that kicks more than the 286 at 2475 fps!! . Call me a wimp but that is enough!!

Dirty old typos. Yes, 150 is correct.

This one is 7 pounds 11 ounces with a sling and belly full of ammo. I don't want Andy's 2610 FPS loads either. My 286 RNs at 2350 killed a bison...that's good enough for me at this point.

 

[Why not?]

Every time I see that rifle, I want to clone it BUM, except for the length of pull. That is about as classic as it gets. All the stock needs is side panels alongside the action, and it could have come out of the very early 1900s.

IIRC, your dad made the rear sight, right?

Thanks for showing it again.

Your memory serves quite well. Dad made the rear sight and pitted the front sight to the barrel. That took some doing.

PRVI is holding better than partition so far .... and i really like the partition in 9.3s and 375 ....

Prior to acquiring my 'inexpensive' Zastava



at a local gun show I picked up a set of RCBS dies, including a neck sizer. In addition, along with that was a 'quantity' of new Lapua unprimed brass and some 285gr PRVI bullets. In anticipation of doing some load testing, primarily for accuracy, I've also gathered up a selection of other bullets in a variety of weights. With the accuracy I obtained using the PRVI bullets and my first couple of trial loads, I haven't tried any of the other bullets, yet.



So,Phil, glad to hear the PRVI's are holding together so well, compared to the partitions.

 

[medvedqc]

Johnn: i have more partition than partizan bullets but honestly in those speeds hard to believe how the PRVI is good. at least on milk jugs filled with water ...

Well, I won't be spending much time in the field this season, unless I luck out and get an earlier date for correction of my cataract issue. However, the PRVI bullets should be more than adequate for the monster Blaxktail Deer here on the island. I will do some trials and testing of some of the other bullets I've acquired but I wouldn't hesitate to use the PRVI bullets.
