Big Tom,
Go get the 35 Whelen, great gun/caliber for anything the big woods has to offer.
I am not an expert, but have had enough experience with the 35 Whelen to address your questions. I have a M700 Classic in 35 Whelen and the rifle shoots under MOA with handloads. Target shooting is done with the Seirra 225 gr bullet and hunting is with the Nosler 225 gr Partition.
I once shot a 2.5" group with 225 gr Seirra at 300 yds off the seat of a 3 wheeler.
I have taken 17 WT deer and a 250 lb Black Bear. I only blood trailed 2 deer, which were 30-40 yds and the blood was very heavy. The rest were bang-flop kills. Always get a nice exit wound with the Nosler 225 gr PT's.
Let me know if I can be of any additional help.
Regards,
