Currently I'm shooting 100 gr. slicks on 3-49 acc with blazers and I have to admit that they shoot really good with my fields up to about 25 or so yards but at 35 yards they shoot about 4-6" low. Is this normal even if my bow is tuned?
 
No that isnt normal at all. Sounds like there may still be a tuning problem. Maybe the nock point is off a little or the rest itself may need tweaked.

When your bow is tuned properly.. they should fly the same.
 
My blades shoot pretty close up to about 40. After that the wind seems to effect the flight compared to the field tips.
 
Yes that is normal. Too many folks are trusting the "flies just like field points" sales pitch. Just because the grain weight is the same, doesn't mean they will fly the same. ESPECIALLY at longer distances. Lower profile things (like field points) don't catch as much wind as larger profile things (like broadheads) so on further distances, the impact point for a broadhead will usually be lower than your field points. Now hitting to the lefts/rights will tell a tuning problem in windage but otherwise, it is normal for them to hit a lower impact than your tips. That's why you should ALWAYS shoot your broadheads prior to hunting with them.

There is an article in the Nov '09 issue of Bow & Arrow magazine that Joe Bell discusses this very question in detail.
 
Ghost, if you are loose 4-6 inches between 25-35 yards there is something off. If your setup is shooting good at 25 yards.. and loosing that much 10 more yards.. something is a miss.

Are you using a different pin for 35 yards? Are you field tips hitting right on target at 35?
 
Guys,

Try this: paper tune your bow with broadheads. Robbie at Mid South Archery (new shop in Rossville, TN) suggested that to me about 2 weeks ago and it works. I shoot Montec fixed blades. We aligned the blades with the fletchings so you don't get a wierd tear. I was shooting bullet holes with field points, but was getting left impact @ 30 yards, only about an inch. We moved the rest about 1/32 inch to get it correct with the broadheads, and at 30 yards shooting a broadhead first, then a field point, the shafts were touching!

If you think about it, tuning with broadheads on is the most sensitive configuration, so if it shoots "correct" with the most sensitive config, the field points should follow.

I've been in this game for almost 30 years and this is the first time I've had absolutely no difference in field point and broadhead POI difference. That's worth loads of confidence going into the season.

If you're in the Memphis area, check these guys out. Jason owns the shop, and has a few of us helping out. They're very good technically and can special order just about anything you need.

Good luck this weekend.

Yes I do use a different pin at 35 yards and my FP do hit right on. I will try today when I get home from work to adjust my rest up about 1/16" like Radar suggested.
 
Thanks for the input. I didn't adjust anything. The problem was just me.. They fly just fine. I think it was really due to poor form.

Yes the November issue is already out. I got mine last week at Books a Million. Joe Bell is one of the best tech guys in the industry.

I like his his tech articles in Bow and Arrow . I might have to get the book . I read everything Randy Ulmer writes too.
