As the title states. Does anyone have any good cast loads for these calibres? I have purchased some 225 gr .358 cal bullets and 286 gr 9.3 mm bullets from jet Hunter and need a couple suggestions. I am looking for some plinking loads all the way up to about 2000fps. I have Trail Boss, H4198, H4895, IMR 3031 which I am guessing is a good starting point. I also have an assortment of longer burning powders not listed. Any help would be appreciated:)
Thanks
 
Trail boss for small game loads work great for me in 9.3 x 62, about 5 grains covered with Dacron.

Of the powders you listed H4895 in the 40 grain range would be where I would start for a big game load in the 9.3 x 62 as well.

35 Whelen just trim off a tad from 9.3 x 62 loads and carry on....
 
I have used the following loads in MY Stiga Swedish M96 based 9.3X62 with fairly good results, pressure mild and grouping OK by my standards. All loads are hard cast 280 gr. bullets from the Bullet Barn in reformed 30-06 brass.
14.0 gr. Unique, 28.0 gr. IMR4198, 13.5 gr. Trailboss, 16.7 gr. Bluedot..
 
I used 20 grains of 4759 and a 210ish water quenched WW GC bullet in the 35 Whelen, 350 Rem should awful close.

I had a bit of a pattern going for awhile, 14 for 30-30s, 16 for .308s, 18 for 30-06s, the 20 for the Whelen. Magnums in general jumped up to 25. It always seemed to be about what the bullet could take, exceed it and accuracy feel apart.
 
Ken Waters gives the following loads in Pet Loads:

350 Rem, 226 Lyman 35897:
21gr 4227 for 1556fps ("good")
27gr 4198 for 1700fps
32gr 3031 for 1560fps ("best")

35 Whelen, same bullet:
26gr 4198, 1692fps
35gr 3031, 1883fps

He also used a 252gr bullet (358319) with 21gr of 4227 in the Whelen which ranked "best" in accuracy at 1525fps.

Posted this in the cast bullet #### thread quite a while ago. How's this for a hunting load? Northman 285 gr plain base straight wheelweight metal at over 2200 fps muzzle velocity has worked very well for me in the 9.3X62.


The loads feature a wad of half-inch square of old cotton towel tamped down over the powder and under a Cream of Wheat filler. The wad protects the COW filler from powder gases, the COW filler protects the base of bullet, and scours the bore clean with every shot. No leading, absolutely none, and groups are consistently two inches at 100 yards.




This bullet penetrated six four-litre jugs, and was caught in the seventh in water test. That's over 36" of water and about an eighth of an inch of plastic!



You can see how cleanly the bullet is engraved by the rifling, and that the base of the bullet has not fused at all. Will have to check my notes to give you the retained weight of the expanded bullet. Just checked, and the bullet pictured weighs 204 gr, a bit over 70%, and is expanded to almost 45 caliber.



There was no unburned powder in bore or on the snow, and best of all, no leading! One patch of bore solvent, and one of KROIL, and it is ready to go again!

Hi KG,
What is the weight of that 226 Lyman 25897 bullet. I cannot find it on the Lyman website.
Thanks
 
As my taxpayer service agent would say, you should have read 35897 :yingyang: .

You might find some loads at castpics.net, like:
http://castpics.net/subsite2/ByCaliber/The%20358009.pdf

Their cast bullet data lookup has the 350 RM and the Whelen.

Note that LEE has a new 358-200-RF mold. You can find some chats about it or the Whelen on castboolits.
 
My best load in 9.3x62 with 280 gr cast bullet (Mauser98 26in barrel)
48 gr IMR4895 = 1980 fps (about 85% fill)
Low pressure load under 40K psi.

Traces of copper in the bore from shooting jacketed bullets can cause some leading. You should scrub the barrel well before shooting cast the first time.

For a new barrel you should shoot 10-20 jacketed bullets before trying cast bullets. Sometimes there is still some working edges left in a new barrel from the rifling process and jacketed bullets will smooth them out so your cast bullets will be less prone to leading.
 
If you don't have cast bullet data for those three cartridges, you can safely use 358 Win data for a 250 gr bullet for all three with both the 225 gr and 286 gr bullet weights.
