Mule deer. Tell Nosler to make 286 accubonds?

MD: Nosler load data shows a maximum load of 56.5 grains of Varget with a 250 AB and a velocity of 2525 with a 26" barrel. You state 2600 - 2650 fps. Is your 9.3x62 especially "fast"? Thanks.

He’s loading the round to modern pressures akin to an ‘06 or .270. Load manuals keep pressures low in deference to old rifles. JB has pressure tested his data, and many of us have used it with spectacular results.

FWIW, I was doing some chrony work with My son’s rifle and the AB/Varget combo recently. His 20.5” barrel gets 2495 fps. My 20.5” barrel gets 2525.

This is what I get with my FN based 9.3x62 . So I don't think its especially "fast" . Hammer bullets has 258 and 240 grain mono's I'd like to try, ordered a 15 pkg but have not had an chance to load them up as of yet.

I referred to JB's Handloader article and this chart when I had my 9.3x62's.

I just ordered some 250 ABs but am not sure what they will offer over the 286 NP.

Maybe a tad slicker flying to the target.

Doubt you or critters will be able to tell any difference.

For fun I'm going to find some area where we can shoot a long ways and see what they will do.

Hi,

I have and use as my main rifle now a BRNO ZKK 600, made in 1967, in 9,3x62. It is, to me, the best fitting of all my big game rifles!
I use the loads published by M.D. with almost identical results. I use R15 with 220 and 250 grs bullets and W760 for 286 grs bullets.
I think would be difficult to find better, for one bullet weight/type for all, the 250 grs TTSX and GMX I have, plus the Accubond 250 grs I don't have, and R15 as the powder.
Best!

Could you tell me how much R17 please sir? Thats kinda the data im seeking for the CEB.

bluefish,

The 250 Accubonds don't offer any on-game performance advantage over the 286 Partitions. But when started at 2650 or so they have about the same trajectory (and retained velocity) beyond 300 yards as various other cartridges using heavier spitzer started at around 2700 fps, whether the 6.5x55 with 140s, 7x57/7mm-08 with 160s, or .30-06 with 180s.

In fact the 250 AccuBond has pretty high G7 BC, for a bullet of its diameter and weight, of .494--which checks out on the range. This is slightly higher than the 286 Partition's .482--AND the 250-grain .338 Partitions .473.

You may not care about such things, but I have used the 9.3x62 as my primary medium-bore cartridge for almost 20 years, during which my .338 Winchester and .375 H&H haven't been used at all. I hunted with both a LOT before getting my 9.3x62, but came to like the 9.3x62 more, because it could do basically the same things with less recoil (due to using less powder). In fact I found that in general it killed somewhat better than the .338, probably due to the larger bullet diameter.

All of which is why I like the 250 Accubond as a general-use bullet in the 9.3x62 (or 9.3 Barsness-Sisk): It has penetrated more than sufficiently on big (not just deer-sized) big game, and makes shots at 400+ yards not just possible but pretty easy.

I looked in Africa because it is traditionallyanAfrican caliber and yes i do have a way to get somchem the powderscheap theshippings not but i can get it if i want it bad enough. I understand your position but i didnt know writd the gunwriters would help. This forum helped a great deal,and "africa" has been fruitful to me but can youtell me where to go better id appreciate it.

At least one poster suggested the "Big Game" forum in the Reloading subsection of the Campfire, which is toward the bottom of the list of forums. "Ask The Gunwriters" is also good, and it's near the top of the list, below "Hunter's Campfire" and "Hunting Optics."

I have only minimal experience with Somchem powders, but from their loading data I would guess many far more readily available powders will do as well or better.

I got them already!!! Thanks!!!

Im primarily concerned with 2 bullets just right now. The 280 grain solid Cutting Edge Bullet and the 200 grain raptor pointed Cutting Edge Bullet at max speed andthe280 at around 2400.
I want info on all bullets yall have.

I only load my one load so I'm no authority but I know you can't go in a store and see rows of 9.3x62. Even on line I don't see several factory loads jumping out at me. To me for use in the U.S. the 9.3x62 is mainly a reloading proposition.

Have not used the 210 Raptor but have loaded the 200-grain flat-base Raptor to 2850 fps with 66.0 grains of Reloder 15.

For any bullet (lead-core or monolithic) in the 286-grain class prefer Ramshot Big Game, around 65.0 grains depending on the bullet and the velocity desired. Have gotten 2500 with various bullets from the Barnes 286 TSX to 285 Norma Oryx out of the 23.6 inch barrel of my CZ 550; for 2400 around 60-62 grains should work. Big Game is a very temperature-stable powder, and have used the same basic load from below zero to over 100 degrees Fahrenheit with excellent accuracy and no problems.

I like CEB bullets. Never tried them in my 9.3x62's, but did in the .308 and .375 H&H.

Check out my review on the 135 Raptor out of my Broughton barreled Kimber Classic .308.

I shot a one hole group out of my M-70 NH Classic .375 H&H with this one. No blood yet. Too many other projects.

They're expensive, but I don't actually shoot that many bullets at game. Practice with something cheaper.

Terminal performance is great, as is accuracy. I understand some PH's in Africa like them. I've read that in brush, they can come apart too quick if they hit something. I'd use them in open country, something else in a thicket.

Hello M D,

Have you tried the W760/H414 with 286 grs bullets in your 9,3x62? Here W760 is the only ball type of relatively slow burning rate powder we have...at least for a while...The same question for H100v. In your opinion, is the H100v good enough for charge densities able to obtain adequate pressure/velocities with these 9,3x62 bullet weights?
Also, have you tried W748 with 232 and 250 grs bullets?
I understand these Winchester powders are rather "old" powders in regards to temperature sensibility and residues they leave in the barrel but, again, including the H100v, they are the only ones available here right now...!
Thank you very much!

Patagonia Hunter,

I have zero experience with W760/H414 in the 9.3x62, for the temperature reason you state. But would not be surprised if they worked pretty well, since their burn-rate is similar to Big Game. H100V has a somewhat slower burn-rate, so it might not be as suitable. Have not tried 748.
