I'm looking for a load for a 30/30 = 30 WCF with a 200 grain 311299 and IMR 4350. I used 30 grains yesterday and had a lot of unburned powder in the bore. It shot fair. There's not a lot of room left in the case with 30 grains, I'm looking for the max safe load. Maybe with quickload?

Joe,

In order to give you something that close, you need to provide the length in .000 of the bullet, the OAL of your loaded cartridge, and your bullet weight, I'll run it for ya.

Since you mentioned it above, your amount of propellent burn well over maxium is still only 87% which means that you are still going to see unburned powder no matter how high you go. Just so you know.

But if you

The bullet is 1.208" long just now with GC on, OAL is 2.875".Bullet weight is 206 grains about, varies with hardness. I really want to know if a full case of IMR4350 is safe with this bullet.
Thanks;

Joe,

Says you have 38 grains of usuable case capacity after seating the bullet.

36.5 grains is 40,118 psi for 2017 from a 20" tube and the powder burn rate is 90%. Just 1/2 grain more puts you over 42,000. If your chronograph pushes you over 2000 fps before you get to that point then your barrel conditions are producing higher pressures. Because velocity is the result of 40,000 psi reguardless of where you reach it. Just so you know.

Good Morning, BA;
The case capacity is a Lee 2.5cc dipper of IMR4350. The enclosed table with the dipper set says it should weigh 34 grains, it does weigh 35.3 grains.
This fills the case to the base of the bullet-maybe shaking would settle it a little bit. 36 grains would not fit.
The rifle is a M54 Winchester with 24" barrel.
If I read you right, a full case = 35.3 grains of IMR 4350 would be a safe load. Is that correct?
Thanks;

Joe,

Oh hell yea. The program uses 42,000 as max for levers. In a bolt, you have the limit of the brass which I should think is 48 to 50,000 psi with reduced case life. Plus the velocity was quoted as for a 20 " barrel.

35.3 grains is 37,779 psi for 2036 out of a 24" tube.
