OK, I'm going for it.... I think.
I have to play with what I think is a good candidate for paper-patching, a 375 Ruger. The plan is to run 270ish boolits @ 2200ish. As far as I can tell, I can't get there w/ grease froove boolits, and I have no desire to pay for J-words. Swaging looks to cost a lot, so it leaves me at PPing.
Can I size down a regular boolit to bore diameter, down .010" to use for patches w/ no issue? It looks like it is OK since I don't have to worry about lube grooves.
Do I have to size after patching? I am hoping not, since I often shoot as-cast.
Will water dropped scrap get me to 2200?
Can I use paper that is available, or does it have to be really special? Hmm, I have tried 3 sitting around the house, none worked when they got moist. How wet do they need to be?
If I end up w/ a roundnose or a spitzer mold, will it expand >2k fps, or should it be flat?
If I roll them dry, how do I know when they are tight enough?
I have no measurements yet because I have been hours getting the cerrosafe out. Finally shot it out w/ 10g of 5744 this a.m. Trying to do this on the cheap, so would like to get by w/ one mold and one sizer if possible. I would like to get a 375449 and a .366ish sizer, and patch up and be done, if that is plausible.
I have 2400 and 4064 to work with for powders, as well as faster stuff.
Any thoughts and advice are welcome.
