Dialed Pruf and Sight Tapes

[bipock]

For those of you who shoot these, I need some sight tape help.

20 yards at Test, each 10 yards after that steps at 8 lines (30 is 8, 40 is 16, 50 is 24 and 60 is 32). I would have thought this would be a somewhat normal progression.

When I line up tapes to the index card, I find that I can get 20 and 60 to match, but the others are off. Or I can get 20/30/40 to match and 50 is about 1 yard off, but 60 appears to be 3 yards or so.

I am for certain on 20 and 30 be dead on, 40 might be 1/2 yard either way but pretty consistent. After looking at the tapes and thinking through the general physics, it seems like the 2nd tape mentioned above might be closer to reality as I shoot Axis 5mm at 517 grains, so flat to begin with but as I get further out, they would slow down. Therefore the spacing should change a little.

I do know they offer a custom tape designer but, given I haven't changed arrows and I'm not sure I am going to, I don't really want to pay $10 for something I won't use.

Logical or am I missing a step?

Multi pin or single pin? Is this for a 3D type event or hunting? And if for hunting what are your real shooting distances?

Sounds about right your gaps open up the further out you go. Try one for a while and see, I always end up changing tapes after shooting for a while but it’s a good starting point.

Hunting, elk in September then deer back home

Deer will probably be under 30 yards. Elk could be longer, but I don’t know that I’d let one fly at 60 yards right now. A ton of practice over the summer and it could be a different story. It’s not like I completely miss my target at 60, just not quite where I want it consistently.

For me, if it's the 3P adjustable I'm not worrying about the yardages for my pins because I'll adjust them later. If it's the non-adjustable they won't line up with even yardages anyway, you're going to have to figure out what those end up being separately and adjust the black indicator pins accordingly (as an example they may end up being 20-33-46). So, I'd want my longer roving ranges to line up closer. I also need to know what my maximum effective on a elk sized vital is.

The advantage with tapes is they come off and new ones go back on. So you can adjust an "dial" in your tape as you get more practice this year. That's my .02
