Powder question

[tdale4]

I have a SSK 10" T/C in .300 whisper that I will be converting to a suppressed carbine after I get my approved ATF tax stamp. the barrel will remain 10" but the suppressor will bring the barrel length to the required 16" and it will be permanetly installed

My primary use for this gun will be night hog hunting. I will also be using this gun during the day with supersonics

For subsonic I plan on using 240gr SMK
For Supersonic Nosler 125gr Ballistic Tip

I was going to use H110 but I have read that it is temperature sensitive

I heard that V V N110 is good, but it is hard to find

Would AA #9 or AA 1680 be a good replacement for H110, my primary concern is temperature because I hunt in Texas where it will be over 100 degrees in the day and then cool down to 80 at night so I want a temperature stable powder

I reload for my 6.8 SPC with Reloader #7, not sure if it will work with the .300 whisper
