HI;;;
Anyone have any personal data with this cartridge and powder with the 250, 270 and 285,286 gr bullets ... and chronograph data ...
With molly coated ect bullets ...
Thanks ...

gummy, going to use this caliber this spring? Bear I suspect. Grain for grain the IMR is a faster powder than Hodgdon in 4895. Just leading to a non use in this powder-sorry. Do use RL15 with 59grns. and 286 Partitions @ 2415 fps avg though in 23.5" Lothar barrel. Suspect the velos to be in the low 23's and 286 grainers with H4895.

Never tried 4895, I to think it is a bit to fast for this cartridge. RL15, Varget, Ramshot Big Game seem to work best for me. RL15 is best for the lighter bullets 232, 250, and Varget middle weights and Big Game for the heavy weights.
These work well in my CZ 550.

big game is definately one of the best powders, along with re15.

My 358 Norma thrives on IMR 4895 and your 9.3 would as well. I wish Nosler made a 286 gr in 35 cal too! The spring opener is my birthday here in #9.

Hogdon is the Australian ADI powder.
If you can find out what H 4895 is in the ADI Code I might be able to help as I use this brand of powder with my two 9.3x62s.

H4895 is 2206H, ADI list their best load from 2209 which is H4350, there's not much to choose between 2206H & 2208 which given as an equivalent to Varget in the ADI manual, but the H4895/2206H does it with a few grains less. This is all for 286 gr bullets.

I'd stick with the consensus powders in the 9.3x62. Big Game and RL15 have worked the best for me. You will not be able to beat Big Game with a 286 in the 9.3x62 IMO. It has shot in every rifle I know of that has used it and will just darn near hit 2500 fps in most of them.

I am relatively new to 9.3x62, but Varget was recommended to me when I first started reloading for it. I have been plinking with 285 gr PRVI bullets and 270 gr Mt Baldy cast bullets and haven't found any reason yet to try any other powder. I am more concerned with accuracy than velocity, and I don't think I can do better than one hole groups at 100 yards.

WOW, Thanks for all the replies ......I,ve got a little RL 15 so I will try it ......As I,m in a village getting powder here is a challenge and I have a bunch of H4895 ...........
I want to use it this spring for Black bear over at HomeShores .......The rifle also fits my wife and I may see if she can hit with it for brown bear .....From what I know it is far more effective for them than her 308 would be ......
I will try Big Game as soon as I can get some....I like all the velocity I can get as long as everything is Absolutely Reliable ......

Waterrat ,bear season starts on your Birthday , Thats a good birthday present , tho alot of work ... ..The next standard mag bolt face Ruger stainless action I find is going to become a 358 Norma ..........It is just too good a cartridge not to have and use ...

Varget is my favorite powder in the 9.3x62 but feel your powder choice will make very little difference as every powder I have used in the 9,3x62 has worked most favorably it has not been a very prsnicketty to load for and lets you spend more time hunting than doing load developement.

286 gr partition, with 56 gr H4895 gives 2350 fps in 22 in barrel. 250 gr northfork, with 57 gr H4895 gives 2500 fps. Actual speeds from Chrony. Both very accurate in 2 different guns. Used both loads in Africa with great results!

I reload for friends as well as my own use so I've had the chance to experiment with some other powders in my 9.3x62.

I've come up with a couple of interesting observations: First, any reasonable powder will get you 2300 and usually a bit more with a 286gr bullet. Some stuff you'd never expect, like H-335 worked fine. Accuracy is well, variable, and is probably more a function of your rifles likes and dislikes as well as what you consider "acceptable" accuracy.

Personally, I've had the best luck with Ramshot Big Game, specifically 65grs of it. This seems to hold for 232, 250 as well as 286gr slugs. Granted the velocity for the lighter bullets is not what you can get out of other powders but the accuracy was excellent, consistantly under 2" and all three bullet weights hit close enough vertically (with no noticable horizontal varience) that no sight adjustment is necassary, at least in my rifle.

I've loaded a little for 3 different 9.3's. My little CZFS 20 1/2" barrel - 60gr Varget and a 286 Nosler-2355fps- 1"group
A 23" Kreiger-66gr of VVN550-270 speer-2600fps-1" group
A 25 1/2" Lother Walther- 60gr RL15-250 NF- 3/4" group.
I plan on testing some more loads this summer.

....I made up a bunch of 270 and 285 gr loads today but got too busy with work to drive over and check them on the chronograph ... I need to build a house with a shooting range behind and a remote switch on a chronograph so I can open a gun port and fire when ready .....

,,,,,,Some people don,t understand that a heated , enclosed , lighted chronograph stand is far more important than a big flat screen tv . .. Ol Bull how fast does the 250 gr North Forks go ....???? 250 is my preferred bullet weight in the 9.3 .....

The folllowing came out when I loaded 9,3x62 with IMR 4895 (same burning rate as H4895 according to vihtavuori reloading manual 08) and GSHV 230 gr bullets in 50 cm barrel:

9,3x62 IMR 4895 oal 83 mm:

59 gr= 2474 fps
60 gr= 2506 fps
61 gr= 2573 fps

gumboot458, sorry, it was 59gr RL15. Velocity was 2600 fps. It's too bad there are no more North Forks

Mouse , I had to dig out my metric /sae tape to learn that 50 cm was 19 11/16 th inch ..
Was that a max load ?? Pretty good load with that bullet ......

Ol Bull ..., Hopefully I,m not going to start a rouw with this , but I think a GSC bullet would produce simular velocities ..
59 gr RL 15 = 2600 w/250 . With my Brenneke 21.5" brl . 68.5gr =2750fps w/250 TSX .......
I never tried North Forks so I don,t know what I missed tho I gather it was alot .....I wish Alaska Bullet Works in Juneau would make a 9.3 bullet ...A guy gave me a bunch of Lapua Mega bullets for the 9.3 so I,m going to work up a load for them .....
Thanks everyone for the data ....

you and me both.

gum-boo,

When I first discovered the joys of the 9.3x62 I tried a little bit of everything that was considered a potentially useful powder for use in this cartridge that I had in my powder cabinet.

I use Nosler 250 gr. BT's and still have a good hoard of them, too. Think they work good - or this has been my expereince anyway, they're certainly very accurate.

Like ron williams said - at least my rifle really doesn't care what you feed it - it just shoots great groups with every powder & bullet combination I've tried so far.

I tried H-322, IMR-4320, IMR-4064 and H-4895 with 250 gr. NBT's & 270 gr. Speers. All ended up shoting very respectable groups, I'd say small but .366" bull holes aren't my idea of "small".

Anyway, I digress; 53.5 grs. of H-4895 was the all time looser as far as velocity goes at 2252 fps outa my 20" tube but the groups were pretty much one ragged hole and I thought the recoil rather mild.

Not a max - but a jump of ~ 70fps from 60 to 61 gr load it may be close.

I did some extensive testing some years ago and included the use of H and IMR-4895. As I recall it was a good enough powder, but I found the only powder to use in the 9.3x62 was RL-15, it got me 2525 FPS with a 286 gr. Nosler and 2455 FPS with the 320 gr. Woodleigh in my most recent recent tests. I have only used RL-15 since that time. I do recall that I got decent velocity and very good accuracy with IMR-4895, but RL-15 was my shining star.

H4895 was one of the first powders I used in developing loads for my 9.3x62. I worked up from 60gr of H4895 and a 286gr Partition stopping close to 2400fps. This produced no pressure signs, but the final charge weight was an over charge.

I found that Varget worked better than H4895 and highly recommend Varget. Even though my ultimate load with Varget was also an overload in some manuals, but produced no pressure signs in my rifle and was less of an over load than the previous H4895.

You can find my experiments with 9.3x62 and 250, 270 and 286gr bullets and RL15, H4895 and Varget on the reloading forum under Kudude and 9.3x62.

.......I,m going to try some RL 15 with the 285s . I need to take the time to go chronograph .... ... I,ll stay with the H 4895 with the 250,s for now ... 2600 fps with them makes for an extremely useful load for all around ......

My brother and I used my CZ 550 with handloads featuring RE15 and the 250-grain Barnes TSX in Lapua cases in Namibia last year with excellent results. Wonderfully accurate and temperature insensitive, although heat won't be a factor up your way, Gumboot.
