Daryl,

Relatively new here, but I've been using the combo's that you're asking about and I might be able to assist somewhat.

Regarding the .44 Mag load, anything in the 240gr. JHP range using H110, has always worked well for me out of my SBH with 24.0grs. and a magnum primer. I used to use Sierra's exclusively, but Hornady's XTP's have garnered quite a following in the last couple of years. I also switched back to Hornady's VMax's in all my CF Contenders, Encores & Strikers.

If I were going to use bulk, as with you, I'd opt for the Remington 240JHP. I've used them alot, as well as the 180gr JHP .357 varieties for loading in the Magnums and Maximum's for the last 20yrs. or so, and they perform as well as just about any premium bullet.

I use 99% cast bullets in handguns anymore as I "roll my own".
Magnum velocities get the gaschecked types, but 260 to 300 gr cast hollowpoints work real well on deer, or whatever I've hit with them.

Also, regarding the 7-30 Waters, I did some load work on a friend's gun recently using 120gr VMax's and his report when asked how they performed was......... "stellar!"
He uses a 14" scoped Contender.
I'll relay any info that will help.

Take care,
Bob
