I'm a third year bow hunter who doesn't really count the first two because they were with borrowed or defective gear. This year I got my Magnatec working well two weeks into the season so I opted to use 100g proseries spitfires instead of the 100g thunderheads I bought last year. I was under the gun, didn't want to sacrifice practice time and the dealer said "sight in for the fieldtips and these will shoot in the same hole". Well he was right, I've shot two deer this year (first with a bow), a 100lb doe and a 143lb 5 point, Both from the same stand after 3.5 hours total for two outings! Here's my data

Hoyt Magnetec-Saber cam 28" draw
Beman ICS 400's cut to 25.75 inches
100 grain Proseries Spitfires
Tru-fire release

The doe was a slight quarter shot at 20 yds. Enter back lobe of right lung, liver and then paunch before exiting in front of the left rear leg. I didn't get a complete pass through, about 60% was hanging out. She didn't bleed for about 50 yards, then spots, stopped at 60 yards stood for a while and expired.

The buck was right below me in the treestand, about 20 feet. Got him to the left of the spine, slight angle through a major feed for the lungs and dead nuts through the heart, on to wedge in the breastplate. Solidly I might add. He ran about 3 yards, stumbled into a tree that another 6 yards and fell.

Both hits exhibited major internal damage, effective in the end for harvest. My only wonder is shouldn't I have got a complete pass through on a near broad side at 20 yards and overhead at 6 yards? Is the breastplate that stout? The doe had a belly full of browse from a night full of feeding before a nor-easter would either one of these slow an arrow down that much?

They do shoot exactly where you aim them though, I made zero adjustments when I went to the spitfires.
