>480 Ruger SBH bullets

[ebg3]

Specifically the 345 gr gc Keith style bullet from Montana Bullet works. Bought 100 to try and they look good. Bullet length is .826" and nose to crimp looks like .385". With some loose calculations, it seems like 24.6gr of H110 will just touch the bottom of the bullet in new Starline brass. Would that be considered a 100% load and a good starting point? Was thinking of trying 23 gr H110 to start.
I loaded some 400 gr Lee powder coated bullets with 21 gr H110 and a cci mag primer. With my capacity calculations, 22.8 gr of H110 will just touch the base of the 400 gr bullet. I do not necessarily want to load a max charge of H110 with either bullet, I just want to know where 100% is. I'm curious to try some full loads before settling on a more pleasant load.
I guess another question is will you get into trouble loading a 100% load with H110? Not compressed, just 100% full.

I don't know much but filling to case capacity sure as the world isn't how I decide on a load.....

Lee Precision data listed on Load Data lists a 405 Grain lead bullet w/22.3 grains H110 yielding 1328 f/s and 45200 psi. Primer and case not listed.

Did not find any data for the 345 Montana bullet. Hodgdon did give a max load of 27 grains WW 296 or 27.0 grains H110 with 355 grain Beartooth LFN GC yielding 1464 f/s and 38400 psi. I did not verify these loads on their respective websites.

I do not load for the 480 so I have little to add.

I don't decide on loads by capacity either. I've always heard H110 needs to be 100% and most H110 max loads I've seen for various cartridges are greater than 100%/compressed. I think in the case of the 480, 100% density will be a little heavier than I want to enjoy.
I shot 21 gr H110 with a mag primer and the Lee 400 gr pc bullet yesterday. Primers looked fine and extraction was easy. I'll be trying the 345 gr bullet and will start with 24 gr H110. The data on Hodgdons website seems a little high but they don't have the exact bullets I'm using and I know available case capacity will make a difference. This goes back to why I was figuring where 100% fill is with H110.
Thanks.

Load Data from Hodgdon shows a starting load of 26 grains of H110 and a maximum load of 27 grains of H110 with a 355gr Beartooth bullet. H110 does not respond well to reduced charges as I am sure you are well aware of. Look at the specs for the BT bullet and see if the amount of bullet in the case is similar. In any case, I feel that 23 grains would be too low, and could cause problems.
