Yes, I do usually number and mark the arrows so they are loaded the same way each time and I can keep track of them.
Also, of the last two dozen arrows received from PSE I have not had to reglue anything before using them. They came with the dab of glue at the head of the fletching.
Before hunting I shoot them with my practice broadheads heads to make sure they fly well out to 50 yards and then put a real broadhead on them.
Generally I'm happy if the groups are 1-inch or so with field-points at 50 yards. I don't dare shoot the same bullseye with multiple arrows. Three arrows at the same bullseye at 50 yards usually means a busted arrow.
Stock PSE arrows generally group 3 inch at 100 yards for me, out of the box with 100gr field-points. This is not one arrow shot 3 times. This is 3 different arrows. It takes a windless day to achieve this. The wind-drift at 100 yards is absurd - the slightest cross-breeze causes several inches of wind drift.
This 100 yard 3-shot group, for example, shot last year from the table between the headless elk and the target butt:
The black cut-outs in this target are about 3-inches or so. I consider this accuracy pretty acceptable.
I had an 8 year old kid shoot a 4-inch group at 90 yards the first time he tried shooting at that range. 3 different arrows.
Maybe shooting with the stock Whisker Biscuit is the key?
Maybe I've just gotten the luckiest matching set of arrows ever built by PSE?
I'm sorry to hear you're having so much trouble. I really find the stock Tac15i and stock arrows to be quite robust.
