Broadhead/bow terminal preformance questions

[sneakboxer]

I shot my first deer with a bow on Wednesday and have a few questions for the pros.
I'm shooting a Parker Blackhawk @31in and about 63-65lbs. I'm using older Easton 29.5in carbon storm 340 arrows and (sharp)Muzzy 3blade 100gr heads.
I put a good shot on a buck, hitting him just behind the front leg, breaking one rib and catching both lungs and the top portion of the heart. Due to the ridge i was hunting on the shot was at a gentle angle and at 25yds. The arrow only penetrated 8in with the broadhead lodged in the off-side ribs. He only went 50yds and crashed hard. The blood trail was usable but not the greatest.
Questions: Is this normal? I was hoping for a better trail and a pass through at this range.
Is this a tuning issue? for example my arrows hitting at an angle. I'm grouping better at 30 than i am at 20 but chalked it up to more concentration made me shoot better. I also have vane marks on my fall away rest. Accuracy wise I'm shooting 2-4in groups all day long.
Arrow spine and weight issue?
Add more draw weight?
Different BH?
Here is a pic of what was left in the buck. Note the bent blade.

Sorry for all the questions and i'm not complaining about the performance - dead deer in 50yds is pretty good in my book.
I just want the best for the critters sake.
Thanks

I have had only one muzzy not pass through and that was a direct shoulder hit. I would be concerned about the fletching clearance. Your arrow may not be flying true and using up some of your K.E.

Also, if you hit a rib going in and coming out, that significantly slowed the arrow. I agree with MWoodard, get the fletching clearance issue taken care of first and I think you'll be ok.

I had issues a few years back almost exactly like you describe....My rest was not true (straight) on my bow causing alot of KE loss. I adjusted the rest re-sighted the bow and have had nothing but pass throughs, Did have one that took out a rib and hit the other side as well but the arrow went three quarters of the way through and fell out as the deer was running away. If its a fall away, the fletching slap is pretty significant to leave a mark. Definately tune her up and I bet your results will be like mine.

It is worth the time and effort, IMO, to paper tune your bow. When you get it shooting "bulletholes" you can have confidence that you are not wasting KE for untuned occilations and are getting top performance from your setup. It can be amazing the difference that moving your rest L-R or U-D minute amounts can make.

Thanks guys. I was kinda thinking that. I was admiring the engineering of my bow in the tree one afternoon when i noticed vane marks on the rest. I thought this was not right being a fall-a-way. I also noticed porpoising but discounted it as an optical illusion due to different colored vanes.
When i bought the bow i thought the tech set it up too fast and did not put alot of time in to it. But discounted this to the new super bows compared to my old beater.

Edit: i thought some thing was up with better groups at 30 vice 20. Similar to long range rifle shooting where a bullet needs time to settle out. Where 100yd groups are worse than 200yd groups.

I feel bad knowing that i did not go afield 100% ready. Well its off to the bow shop for me.
I'll report back when i get her shooting strait again.
Thanks,
