Not me, sticking with my fixed blade nitron. I think I disagree with them.

It would seem to me then that if you are using a 100 grain broadhead on a 20 inch bolt, in general the lighter the bolt the more FOC. Maybe that is why my 410's fishtail and my 350's do not with the same broad head.

I like the idea of a little less spin. Although I really don't know how much my bolt spins now. Sort of hard to tell. I like my combo's I have but it is nice to hear other ideas. I wonder why a more forward FOC helps grouping. I know it causes a little more drop in trajectory, but what about it help...

I would love to hear a discussion on vanes. Feather vs plastic, 2-3-4-5- inch, degree offset, blazer vanes. It is just a discussion so if anyone has anything to add feel free. I know very little about that, but I sure would like to learn.

Not my thread but I know summer won't mind.

I don't really know anything about the blazer vane Summer. My ten point and my beemans both have I think a 4 inch, but my Gold tips have a 5 inch. Hard to say really why they fly better. I don't know that much about all the intricacies of bolt flight. But I do know the setup I have is very accurate....

The rocket analogy is interesting. At first I thought is that really ballistics, well yes it is. But it is different in a very important way, like an aircraft a rocket carries it's propulsion system with it. So at least until burn out, it does not have the same type of ballistic behavior as a bolt o...

True speed can cause instability. But remember, in this day and age the speed of a bolt is really quite slow compared to other type projectiles we have mastered. So the difference in speed between a 350 and 450 in my experience does not effect flight. That is if the bolt is set up properly. My most ...

Also think of trajectory and the forces of gravity. It is similar really to wind effect. It is just force over time applied to an object. So the faster a bolt fly's to the target the less it will drop. I realize there are other forces involved in drop like FOC, but in general the amount of drop is g...

There is a lot to ballistics. There are many things than cause a bolt to fly differently I agree. But I think in general if we are thinking about wind effect. Whichever bolt gets from point A to B the fastest will have less wind effect. By that I mean the speed of the wind will have less time to eff...

I shoot 345 grain bolts from my emag, and also with the forward riser on it. So it is an emax. Gold tip II with 100 grain nitron. Very accurate and fast.

It stands to reason that the faster and heavier an object is, the harder it will be to knock off course. Faster vs. heavier . . .where is the trade-off? Is the weight more important than the speed when talking about stability? I know speed is better for getting the bolt to travel flatter . . .but, ...

Wow, poor bear. I am surprised that does not happen a lot.

Unless it has the accessories it is about $75 dollars higher than on ebay.

Oops I bet you are talking Canadian, never mind.

Well like I said not sure about ballistics of the bolt. But I do know an F16 and a C5 will drift exactly the same degree if they are traveling in the same wx system and traveling the same speed.

It seems it would work this way on bolts also. But I could be way off.

That looks completely impractical.
