using jacketed bullet loads for cast

[Oklahoma Rebel]

I seem to remember hearing, for example, say I have a 250 grain boolit(cast) in so and so cartridge, but cant find cast load info, that you can use 250 grain jacketed load info ( same powder/cartdg obv.) by reducing it by 20% or something. I'm pretty sure someone here said that, just wondering if its true, false or what? thanks, a lot!

Depending on the cartridge I use jacketed load data straight up for many of my powder coat loads. A powder coated 311413, water dropped after coming out of the oven runs great with a starting charge of Varget [for a 168g BTHP] in my FAL.

It really depends on what you're working with

[dragon813gt]

Reducing charges will be powder dependent. You can get in trouble real quick if you do that w/ a powder such as H110/W296. I use the starting charges and work up from there. For reduced loads in rides I'm using pistol powders and there are no published charges for that application.

[Oklahoma Rebel]

it would be with something like 4895, and I know about the 60% rule, is that rule fairly universal with the powders in the 4895-4350 range? I am saving for a 9.3X62 and there just isn't much in the way of cast loads, lee is all jacketed, and lyman doesn't even list that caliber!

[w5pv]

Find a mouse fart load work up from there,personally I have never had a problem with this procedure using any powder.

[Texas by God]

You can find heavy bullet data for the .35 Whelen and use that.

[Hardcast416taylor]

I use jacketed bullet load data with my paper patched boolets. I start at the lowest loading listed for a powder and slowly work up from that.Robert

[Oklahoma Rebel]

ok, cool. I use oven heat treated, gas checked boolits of lyman #2 w/ .5% copper, I think around 20bhn after ht'ing, and I use homemade moly lube. thanks for the info guys, and if anyone knows anything else about the 9.3X62 that I might need to know, let me know!

[Yodogsandman]

That 9.2x62 seems like a headache. Many in the past have suggested using 35 Whelen data. Simpler to just use an all American, 35 Whelem.

Down here the 9.3x62 out numbers the .35 Whelen 20-1, I have Accurate mold 369-285B with my lead mix it weighs 292 grains the load I use most is 20.0grs 2400
I have tried H4895 and Varget started with the jacket minimum load and worked up pressure was too low and not sealing the chamber was getting lots of soot down
the cases and accuracy was not good too many flyers, will try some faster powders like 3031 and 4198 see if they work better, have not chronyed the loads only use it
for close bush hunting need accuracy more than speed any load doing more than 1300fps is all I need

[Oklahoma Rebel]

do you think reloader 12 would be a good compromise? and as far as the whelen, I would have to buy a Remington 700 bds and have it rebored, or buy the 35 whelen rem. 700 cdl, which has a 1-12 twist,( I was hoping for 1-14) and I would have to have iron sights mounted on that one, both being over an extra 120$ after the cost of rifle. if CZ made a 550 in the 35 I would get it. but I like the history of the 9.3 as well as the extra power.

[Oklahoma Rebel]

actually on the bottle it says REL12, it a tall narrow black bottle

[Oklahoma Rebel]

also did you use a strong crimp or no crimp? I like using the lee collet crimper or "factory crimp die"

[dragon813gt]

While I don't load for this cartridge I doubt you will have to crimp. Use a proper size expander for correct neck tension. Then all you have to do is remove the bell on the case mouth.

[Oklahoma Rebel]

I just mentioned that because I thought it might help with kiwis problemof soot on the cartridges, means low pressure and unburnt powder. a good crimp will help with that

[Oklahoma Rebel]

and also I crimp so I can toss a box of shells in my pack, jump in the truck and go hunting without worrying about anything moving, also recoil, especially in a med bore rifle can move boolits around if they aren't crimped. it just makes me feel better

You like the More Power of the 9.3 over the Whelen ?
What are you hunting.
The .35 Whelen will knock the snot out of a Moose.
Are you planning to go to Africa or Alaska ?
But the 9.3 does punch a little bit bigger hole in paper, but not much.

But there was one other advantage to having a 9.3.
Back in 2008 when all the ammo and reloading components dried up, the only thing on the shelf was bullets for the 9.3 and a couple boxes of 9.3 ammo.
I remember telling my friend, I wish I hadnt sold the old German Drilling I use to have in 9.3

[Oklahoma Rebel]

whats more American than having more gun than you need, do you really need 400HP in your daily driver? no but why the h not! lol

[Oklahoma Rebel]

I would like to go on a moose hunt in the next few years, so it is not out of the question, and also hogs can soak up a lot of lead.

[sharps4590]

As has been mentioned I'll use jacketed data for cast bullets dependent on the cartridge, rifle or handgun and powder.

As far as the 9.3 X 62 over the Whelen....some of us just prefer something a bit different or out of the ordinary. Both cartridges are excellent, no question of that. My cartridge of choice in that class is the 9 X 71 Peterlongo. Not quite as big a diameter but the extra 8-9mm in case length more than makes up for it....if I ever need it, which is rather unlikely.

[Oklahoma Rebel]

thank you sharps, I would love it if you would post a pic of that cartridge, I've never heard of it. is it a german gun? and what powders do you prefer for 9.3X62/ 35 whelen class cartridges? (using a 250-300gr boolit)

[sharps4590]

It's actually an Austrian cartridge out of Innsbruk I think from about 1917, maybe earlier, I forget. From what I've been able to learn it was one of a series of proprietary cartridges developed by Johann Peterlongo. I'm aware of an 8mm and 9mm. I don't know if he ever necked it up to 9.3 but it seems such an obvious thing to do I expect if he didn't someone else did though I've never seen one in 9.3. Peterlongo's rifles were/are exquisite. I think I have a picture, if I can find it and the site will allow my posting.

Ah!! Got lucky! It is the second from the right. Data was non-existent so I had to work up my own and used IMR-4064 for that cartridge under a 200 gr. Sierra round nose. I'm confident a load with either H or IMR 4895 would be just as good. The others are some of the obsolete, obscure and nearly unknown cartridges for which I've been fortunate enough to have acquired rifles chambered. Obsolete only in the sense that they were never popular or even known on our shores. Compared to anything in their class they none lack suitable performance for their intended use. All are German or Austrian save one, the second from the left. No one on 3 continents has any idea bout it.

I suspect IMR or H 4895 would provide good to excellent results in either the Whelen or X62 case. No doubt others would also but honestly I have precious little experience with other brands in cases of that class. There's also a pile of guys who have worked extensively with both cartridges, I have not worked with either. I would definitely be looking at something in the Reloader series. I've used a lot of RE-7 and I really like its performance so would expect similar from one of their powders suitable for the Whelen or X62. My oldest son uses one of the Reloader powders in his 6.5 X 55 and loves it. He also likes H-4831SC for the cartridge.

[Oklahoma Rebel]

I like reloader also! but it seems rel 12 is a little fast and rel 15 is a little slow. 15 is popular for the 9.3X62, but with jacketed bullets. so I will probably go the h4198 route, and I will probably change my mind 3-4 time before I get anything! lol, Travis

[sharps4590]

Well, Ben Franklin said "only a fool never changes his mind" so it ain't a bad thing.

[Wayne Smith]

Second from the left - no one on three continents knows what it it? Have you sent a chamber cast to Dave Davidson at CH4D?

[Oklahoma Rebel]

I meant imr4895, not 4198, sorry. my plan is to order a 4 cavity mold from accurate, with 2 285gr, and 2 240-260gr boolits. that way I have a good option for whatever.
