Thanks Orion! That makes sense. Since I'm only 11 days out from deer season, I will wait until spring to make any more adjustments. But I may increase my point weight then.

My total arrow weight from nock to point right now is 440 even. I'd like to bump it closer to 500, but I think I'm good for whitetails for now.

Tennis ball sized groups at 15 yards is pretty darn good.  You must be doing  things consistently.  Correctly -maybe /  maybe not, you'll find out later.

I'd stick with it those arrows for now (without cutting too many more of them)) and practice practice, practice, practice, practice, and practice even more.

You'll tweak your form multiple times, multipe times, and multiple times and eventually you'll acheive a feeling in your shot cycle that's goooooood.

When your shot cycle starts feeling like second nature to you, and your bow and arrow feel like an extension of your body, you'll almost salivate when you focus on a small spot that you're about to draw on.  If you're feeling this and consistently grouping tennis ball size or smaller day in/ day out - your arrows are pretty darn well matched to you and your bow.  You may be able to tweak things to even better - but tennis ball groups at 15 is good to go for hunting.

Out of curiosity, do you know what the string material is on that Montana? It matters.

Thanks for the encouragement Darryl! I am pretty tough on myself when it comes to getting things right. I want to be as ethical a hunter as I can be.

Mike, the string is a D97 Flemish, the factory string. I'm planning on ordering a custom one soon.

D-97       good to know.

Not trying to be a smarty pants, but the most obvious solution is to buy some stiffer spine arrows/shafts.

Thanks for the input John. I know I may have messed up and purchased the wrong spine shaft, and I know I could purchase more, but it's just not in the budget to do so right now. Those things ain't cheap. haha
