Thanks for the input folks, will see if I can source RL-15 or Norma 203b

couple more pages on this blog on the 9.3, RL-17 would be worth a try if you can find it

https://bigborefan.wordpress.com/2018/05/

found this one scrolling back and forth on the blog calendar and clicking on highlighted dates

Very interesting. I just hope we can trust Bob Mitchell's understanding of ballistics and reloading better than his knowledge of typography - which has only the faintest clue

I don't think you need to trust anything he says, get some RL17 and find out for yourself. A quick internet search will show that RL17 shows promise for lots of folks. His blog is interesting for sure, if you like big guns it's a lot of info.

Sorry Gale, I was making a little joke about his using pages of light-face sanserif type in reverse, an eye-fatiguing no-no until desk-top publishing blew away the wisdom of generations.

Despite complete silence on the 9.3x62 from Alliant itself, I notice Nosler does give RL17 a good wrap, with velocities hundreds of feet faster than our local ADI powders show for 250-grain bullets.

The 9.3x62 is my new favorite, so I'm not going to bag it. I can't see that it really eclipses the 338WM, though, except at close range where its greater frontal area may work better on some species - and there I prefer the penetration of heavier bullets.

With its greater expansion ratio, the 9.3 is certainly a much more efficient cartridge but I'd be reluctant to push its loads just to prove some superiority. For 40 years I used the 338WM as my go-to sambar rifle, not because I wanted maximum velocities but so I could get adequate results without pushing my luck. I'll try to do the same with the new rifle.

No worries sir, I reread my post and came off a bit wrong on my part, I get what your saying about the site. I am new to the 9.3 found it pretty easy to find an accurate load in the CZ's I had. Good luck with you 9.3 and let us know if you try some RL 17

thank you
Gale Johnson

For the record.....Varget is the "go to" powder for the 9.3 X 62....at least that's the way it appears to me.

As to the 250 Accubond, I find it a bit too harsh on the shooter.....I use 250 Barnes and remachine them to 200 grains.....

Make no mistake about it.....the 9.3 X 62 is a lot of gun

The RL-17 is pretty impressive, Ive been playing with it and it bests the RL-15 in every case so far, The 9.3x62 sure needs a 26 inch barrel (25.5 is good) to get the needed velocity to top off a that big bullet, at least on paper, but every little bit counts in the field I suspect.

A lot of time has passed since this post, and my test indicat the RL-17 beats my pet load of RL-15 by 54 fps in one gun and 69 fps in another..I have about 200 or more rounds loaded with RL-15, so can't see changing anything until I shoot the supply up, but its definatly on my agenda, also was doing some testing with CFE-223..but sold my 9.3x62, sent the other one back to the owner and got a heck of a deal on a 375 FN, so Im on that one again..Ive never beenm able to make up my mind on the 9.3x62 vs. the 375 H&H..never will...

Good comparison, Ray (between the 9.3 x 62 and the famed .375 H&H.)

The late Dr. Don Heath (Ganyana)and Dr. Robertson apparently had the same experiences.

I've owned each and have kept the 9.3 x 62. RL-17 makes it sing!

The 250 AB gets +2700 at 0.44" for three at a hundred. Worked great on bear. IMR4320 and RL-15 are quite similar. I've shared my results from RL-17 for the 286 NP with several who've enquired, but +2400 fps for the 320gr Woodleigh is easy from my Tikka with its 22.4" barrel using RL-17.

Thanks folks,

A good friend of mine suggested to me going with powders that make the 270gr Speer work well.

Seems RL16 and RL17 are top of that list so think will start there.

Scrummy

The 270 gr. Speer is too damn soft for me, but would make a decent whitetail load at under 200 yards albeit destructive....A 286 Nosler spritzer will pass it up velocity wise at about 200 yards however, kill clean and not too destructive if kept off bone..

If I were to go with a 250 gr. bullet which is highly unlikely because I have a .338 or three. Id use the 250 gr. Accubond a bullet I dearly love and shoot it at 2550 to 2600 FPS, depending on the rifle.

In the .338 I like the 225 gr. Accubond at 2913 FPS for elk.

I suppose the 250 Accubond at 2600 FPS would be a decent enough elk round for sure, be flat shooting for up to perhaps 300 yards and that's about as far as I like to shoot at elk as a rule, but its just not my pick. I like the 286 gr. Noslers. I also like that 320 gr Woodleigh, I killed my 389 wild bull elk with that load, went in the flank and came out behind the ear, now that's penetration like Ive never seen before, it dumped in within 10 yards of the hit.

Lamar,
Yeah well there is Austin, the shame of a great state..and they breed (free love and nickel beer) and spread like cancer, A good place for M-44s that some complain about!

Hi Ray, Someone told me that the 270gr Spitzer was originally developed with the 9.3x57 in mind hence being a bit softer

Scrummy

I suspect that is/was the case, it makes since as it is very explosive sometimes, even on small deer..

it'd be a case of velocity [again?, as usual anyway]
horrible pun right there although unintended.

the X57 case with a 270 would really be pedestrian.... 2350 +/- 2400?
but I for sure wouldn't want to be standing behind a deer catching one at 150yds.
it'd out 358 win the 358 win for sure.

Hi folks,

Think have solved the powder dilema.

Lovex S062 is apparently very similar to H4895 which gives good velocities and works with REACH (Chemical) compliance.

Scrummy

The Africans have been loading the crap out of the 9.3x62 for years and with a great deal of success on the velocity end, using that African powder..They wonder why we load the caliber down like we do...Guess they don't understand how many lawyers we have needing a job!

Hi Ray,

Lovex is made by Explosia in the Czech Republic.

Is it the same as the Somchem stuff?

Scrummy

I have shared my loads and articles with many here.

I have never tried Re17.

In the last 15 years, Varget (AR2208), Re15 & N150 are my powders. Varget is the top for accuracy & consistency. AR 2209 (H4350) works well too.

I have never gone above 2400 fps with any powder for the 286 gr bullet. I think 2550 was max for 250 gr. Woodleigh 320gr stopped at 2200 fps.

Thanks Gale,
I still haven't seen any RL17 here but have been having good results loading 286-grain bullets in front of ADI 2209 (H4350).

I'm happy to get a nominal 2350fps from both Woodleigh R/Ns and Hornady SP-RP Interlocks and that they both shoot to the same point. For some reason the pointed factory Winchester 286-grain PPs shoot about two inches lower, destroying my hope to use them for long range shots, so I might try to load the pointed Hornady bullets a bit higher, for that purpose.

I'm amazed how long the throat or leade is in the Zastava. Loading my bullets out to fill the magazine I find there is still about 3-4mm freebore, so maybe at last I've found an application for Woodleigh Hydros.

I never had any trouble getting 2500 to 2550 FPS with a 286 Woodleigh or Nosler in my 9.3x62s, how ever I had long magazines and throats on those rifles, I could seat the bullets out half way to the cannalure or basically .366 deep..I really was partial to the Swift A-frame 300 gr. bullet at 2400 FPS as I recall...That bullet at that velocity really made a buffalo hump..but was not impressive on plains game??

Scrumbag,
I can't answer that question, I have almost 0 knowledge of the African powders other than what I read from time to time and that's just load data, and I never use it, as its hard to get in the US and expensive when you do see it on the shelf..Most of what Ive learned is in Pierre van der Walts African Dangerous Game, a great book, and also has more load data for Dangerous game calibers than most if not all the loading books combined..

I just bought a Ruger African in 9.3x62 and have bought quite a number of “blemished” 250 gr. AccuBonds from Midway. I hope to carry this combo to Africa one day for a hunt.

Ive had great luck with those Blems, that's all I use in most of my rifles, they just work..

Norma 203B Start at 56.00 grains and tweak it up.

Hi folks,

Loaded a batch with Lovex SO62 so will see what that shoots like.

Scrummy

The fastest load Ive found with the 250 gr. bullet is 67 grs. of H414 for 2650 to 2700 FPS depending on the gun and the barrel length. My test was with a 24 inch barrel and a Brno mod. 21 SR rifle. the barrel was a Lothar Walthar..Super accurate with all loads. I got about the same with RL-17 and CFE-223, but Ive misplaced that data, still looking for it!!

As I've indicated earlier, my most accurate load in my 9.3 uses 250gr Accubonds over a stiff load of Varget. I have used both blems and Nosler's more expensive boxed Accubonds and I, see no difference in accuracy whatsoever. I usually weigh a sampling of the blems and again see no more variance than I do in their boxed ammo. Other than some minor color variation in a small sampling, I see no difference. I have and will continue to keep a good stock of blems on hand.

According to that list you can use RL powders I suppose...RL 15 and RL-17 are outstanding powders in the 9.3x62..Imr 4320 works also..
