Which powder(s) do you prefer with the 286 grain bullets. I have IMR 4064, H 4350 and Reloader 15 all of which are suitable. Are their others which should be considered?
 
I just posted results for my 9.3x62 Mauser in the Firearms (Up to 0.375) Forums.....

I have not experimented with IMR 4064, H4350, or RL15 in the 9.3 Mauser, but as far as I am concerned, Ramshot BigGame is the powder for the old 9.3 Mauser. However, I've seen hand loaders post that RL15 has worked well for them in the past. Again no experience.....

What 286 grain bullet are you thinking about shooting? If I have a load manual for the bullet, I can probably forward some data along....
 
I use 56gr ADI 2208/Varget with a 286gr Prvi Partisan projectile. This is pretty much a minimum load. Gives 2250fps with a 24" barrel.
 
I have used RL 15 and Varget successfully with 286gr. bullets, Have not tried 4064 but it seems to be the correct burn rate too. I think that H4350 is too slow to be ideal.
 
We were limited to only South African Somchem powder until last year in SA. I've loaded mine with S341, the burnrate being similar to IMR4895. It gets a 286 Woodleigh or Partition downrange at 2300fps with no pressure signs, gives an ES of 15 or so and good accuracy for a open sighted rifle
 
RL 17 and Ramshot Big game if you can get them
 
I used 4064 for the 250 gr bullets and R15 for 286. In two different rifles 4064 shot extremely well with 250gr Nosler Acc Bonds and Barnes Triple Shocks.
 
Quaticman, when you have a moment please take a look at Nathan Foster's Knowledgebase posted on his website
https://www.ballisticstudies.com/ He has a very good treatise on the 9.3 x 62 including recommended powders. I think I may have referred you to this same website for info on your 6.5 x 55 Swede. IMHO Nathan Foster's writings are the first place to go when looking for information on almost any caliber. Admittedly there are many big bores that he does not cover, but the calibers he does cover are spot on.
 
Big game and 286 grain Barnes TSX go together like peas and carrots. Search internet for Fred Barnsnes articles on handloading the 9.3 for starters.

You mean John Barsness?
 
 
Yes John Barsness. I should not smoke cigars, drink, and type at the same time I guess
 
I use the load right out of the Swift #2 manual.

58 grains RL-15 and 286 gr. A-Frame. OAL of 3.160". MV of 2375 from my 24" barrel.
I also use this same load with the Interlock and PPU bullets I use for practice as well.

Nice Report! Im about to pull the trigger on booking the LDE with Patrick. I have been talking about it with him for about 3 yrs now. Romain hit me up the other day with an offer I can't refuse for 2027.

Andrew, I commented that your on 375 H&H for sale was the fair price.

Like I commented, my classic stainless has the original 24” barrel.

Did you buy yours with the barrel already cut down to 21” or did you do it (or a gunsmith)?
