700ml sml conversion with factory contour

[Clifton1011]

Just looking to see if anyone has any recommended loads for a 700ml that's been converted to 45 sml with a .458 barrel and factory 700ml contour. I know I'll have to stay on the lighter side, just looking for any info. Thanks

More details, please. Fullform, bore rider, sabots? 209s, DI, etc?

Has 209 bolt nose kit and arrowhead 209 plug with .030 bushing. Barrel is fluted. I have federal 209a and cheddite 209 primers. I ordered some 200 gr sst's and some harvester smooth blues. Will probably be trying n120 since it's easily found and I do have a lb of it. I Have not shot it yet just received it back from Mcgowen. Not sure what it can handle with having a factory contour

We need to know the barrel contour and length of the shank before recommending any loads.

I think that he did mention that its a smokeless barrel that is contoured to a factory 700ML contour.

Look at the Lee Reloading Manual for loads designed for the 45-70 Trapdoor and Rolling Block rifles. These loads have a maximum pressure of less than 30,000 psi. I used this load data for my "NitroBreech" muzzleloader idea. Notice the Lee Manual on the table during this video.
