So, here goes,

I am looking for a load to push a 122 grain gas checked cast round out of my 30-30.

I have imr 4064, imr 4895, h4198 and ff/fff black dirty stuff. This is all i can get my hands on in my area, and my manual has nothing I can use, does anyone have one?

Use the 115gr data and work your way up. 7gr isn't gonna make a difference.
Seat the bullet at a length that works in your gun or at the crimp groove if the bullet has one.
 
Most cast books do not publish any data for a bullet that light in a 3030

a light bullet = paper only or a small animal

RCBS CAST BULLET MANUAL has some data and it looks like you need a different powder

Of those powders, H4198 is the most suitable IMO. You could work in the 18.0-25.0 gr range.
 
Go to Hodgdon's website for load data, they have all 3 powders you have for a 130gr bullet. Since your using a lighter bullet there will be less pressure then what they list.

I have looked at there data, and There is no selection between a jacketed or cast round. which in that case opens up the can of worms of, Can you use cast bullets with jacketed data.

I have the lyman cast bullet handbook, plentyse of data for my round in it, the issue is powders, I have what I have listed, and everystore in calgary is sold out.

You can, but just don't go near the max loads. It's all about figuring out what your gun likes and doesn't. If you can find cast load data for what your loading go with that, but jacketed data will give you an idea on where to start. Make sure the bullets leave the barrel and that you don't start building up lead in your barrel.


Are you casting your own bullets, or using factory cast?
 
At a pinch, you can safely start at 75% of the jacketed bullet load and work up(or down) from there. Off the top, conventional wisdom has it that 4198 is the best chance, but you can only know after you've tried. There's a fair chance that both of the other powders will work.

So using the same start point? How little can I reduce loads before it is an issue?

I am casting my own, 10-1 alloy
 
I would start at the starting load and work from there in either direction. If you can get it trailboss is an excellent powder that cannot be over charged because of how low it's density is. I will be using it for my steyr m95 and cast bullets.
 
Thats my issue though, everyone in town is sold out. I have looked at trail boss though, and will try it when it comes up, until then, just gotta use what i have
 
I have never used bullets as light as 122 grains in a 30-30, cast or otherwise.
The 30-30 is most efficient with the bullet that was designed for it, a 170 grain round nose.
With the 170 grain bullet you can use the same loadings for cast gas check as you can with jacketed bullets and velocity will be very similar.
With the powders you have, either 4064 or 4895, either variety, will get you full velocity loads with either bullet.

I guess i could expand more, i just want gallery plinkers, and i have data from the lyman cast book for a 122 gas checked using sr-4759, i am just looking for alternative loads using what I have. The 122 is the mould I already have, for this purpose. For hunting I will be using jacketed rounds.

OK then, Andy has already told you that 4198 will be suitable for that purpose.
Just load up and shoot.
 
I use 9 grains of TB with 165 cast RN's... I've never used a bullet as light as 122 grains... I stick with 150's for the most part in jacketed and the 165 RN's in cast.
