Arrows including broadhead weigh in at 425 grains. Broadheads suggested are the Shuttle T, 100 grainers. I sacrificed one to pracitice with, keeping the other 5 for hunting.

Point of impact is inline with my field points. Shooting the broadhead first at all ranges out to 40 yards, the field points group in around the broadhead.

I have done some kneeling, elevated (deck), seated (really hard for me form wise), but I will have to try the elevated heart rate. Good point on that.

On yardages I shoot from known yardages primarily, and I also have done two 3D shoots. I'll head down to Luck Shot in Chehalis and do a 3D walktrough on their course once or twice a month once it opens up in May. I've had a rangefinder for about 15 years, so I've played with one a lot, and that has made my unaided range estimation improve dramatically.

Thanks for the advice. Much appreciated.
