Don't even think about it!!!!!!!!!!!!!!!!!!!!!!!!!!!
That is a shotgun powder and is not suitable for rifle loads. It is sometimes used for reduced loads in centerfire rifle cartridges but this is a dangerous undertaking as load density is not sufficient and hang fires and excessive pressure can occur.
I do have loading data to use Unique for the 243, it's for cast bullets only
Think about a tire with 32 psi blowing up.
Now think about a rifle designed for 52,000 psi blowing up in your face
Any questions :)
PS look at my pics, you will see what a rifle looks like with barrel obstruction. Now imagine the barrel blowing up on the other end, the end with the highest pressure.
Example: 30-06 loaded with a 150 grain bullet will peak at 52,000 psi approximately 2 inches into the barrel and taper off to 12,000 psi at the muzzle of 24 inches.
What brand, type and grain bullet are you loading?
its a 100 grain jacketed bullet I used 11 grains with it an old timer told me to try but I found it to be very innaccurate and wanted to try somthing else
I'm a die hard IMR Fan
For a 100 grain 243 load
IMR4350 with 42.0 grains at 2958 fps
i load plenty of light loads for center rifles with unique i load 223, 30-30,22-250 a few to say the least but there all really light recoling varint rounds to say the least so I was lokkin to put a little more power in the bullet
I've heard of the "so many grains of powder" Unique loads for rifles but there isn't very much published data. IMO it could be dangerous with a jacketed bullet. I use Unique for my .45ACP loads and nothing else.
I have an older Speer manual (#11) that list some reduced loads for a 90 grain bullet and a 105 grain bullet with IMR 4198. These loads could maybe be a starting point for you. The 95gr. loads were in the 1760-1990 fps range and the 105 gr. loads were in the 1750-1950 range.
I'd feel a lot safer recommending the IMR 4198 for what you are trying to do than Unique.
That should have been '90 gr. loads were in the 1760-1990fps range.' I just made my own case for being careful about accuracy of things posted on the internet.
Hodgens H450 with 48.2 at 3100 fps sounds good, but it's a max charge. I would start at 45.0 and work up
There are lots of unpublished loads that will send you to a gunsmith or the hospital! Never ever use a pistol powder in a rifle cartridge unless you have published load from the powder or bullet manufacturer.
