454 Casull Load with cast bullets question

[WESTTX4570]

Just bought  a good amount of cast bullets for my 454 Casull for hog hunting. They are a .452 dia. gc that are supposed to be 360gr hard cast. All the bullets are demensionally exact and look to be cast of linotype. Here is the question, they all weigh in at 338 gr. , would I still use the load data for a 360 gr FNGC or use the data for a 335 gr FNGC? The price seemed to be pretty good for these bullets and the fella I purchased them from in Ky was nothing but great. $25.99 shipped per 100? If I can get a good load worked up for them, seem  to be some good hog medicine.

Thank you,
West

Am I overthinking this and just go with my 360gr. FNGC data? There is 2gr. difference between the Max load given by Hodgdon in the two bullet weights using H110.

Use data for the bullet weight you have generally speaking now what someone claims it should weigh. With a cast bullet most times that's fine. One thing you need to watch for tho is how much of the bullet is in the case and how much is NOT. That changes the capacity of the case and can affect pressures.

If the nose is particularly short on a heavy bullet that means it is intruding big time into the case capacity. I have no way of knowing how those things factor in. Does the maker provide any data for them?

GB,
No Sir, he did not provide any load data. Hogdon shows a min. of 23gr of H110 for a 335 gr FNGC and a min. of 21 gr for a 360 gr FNGC with a max of 26 gr for the 335gr bullet and 24 gr for the 360gr bullet. I do understand the loss of case capacity with the longer bullet seated to the canuler, therefore I will start at the bottom end of the suggested 360gr load data and work up slowly, paying careful attention to pressure signs and accuracy.

Thank you,

My guess would be that you should have no trouble with the data for the liter bullet. That said I don`t think that any of the hogs you shoot will be able to tell the difference if you go 2 gr. lower.

I doubt they would either, lol. Just want to make sure I have enough oomph at 75 to 100 yards, thats about the closest I am able to get to these jokers around here.
