Nubbs,
You stated it perfectly.
C903,
All I can say is, every time I' ve tuned my bows with my methods, my field tips will stack arrows together, my fixed broadheads will stack arrows together and my mechanical broadheads will stack arrows together. All with the same point of impact out to thirty yards. There are quite a few other accomplished archers here who are basically saying the same thing. You however, don' t seem to be able to accomplish this. If you were a new archer, who would you listen too?
The only problem I have ever had with broadheads not hitting like field points was with an underspined shaft. They would punch perfect bullet holes and stack arrows with field tips and they shot broadheads well in the yard, but the slightest form flaw would make the BH' s impact differently. Those shafts turned out to be slightly underspined with that bow which made them very sensitive to form flaws. Not a good hunting setup. Went to stiffer shafts and the problem was solved. This is the reason I tell people to stay on the stiffer end of the spine range.
Why you would try to tell me and these other archers that our methods won' t work when we' ve been doing it for years is beyond me. Are we supposed to quit using a tuning system that is tried and true and start using yours, which requires the same amount of tuning time AND resighting or changing sights altogether every time we want to switch between field points and broadheads? The next time I want to take a flying leap backwards, I' ll give you a call.
I' m surely not having any trouble tuning my setups and they' ve been consistently punching 2" cut, 3 blade Vortex heads completely through deer for about seven or eight years now. That' s out of a ten year old bow set at 60 lbs. I see no reason to fix what ain' t broke.
Anybody reading this is welcome to try both ways and choose for yourself. As long as your shafts are properly spined, leaving the bow as straight as possible, you' re grouping well with broadheads and getting good penetration on game, you will be a happy camper. How you get it there is your choice. Just please don' t be so pompous as to insinuate that your way is the only way or the best way. There is no best way, there are only different ways.
