When I asked Kirk if it was OK to shoot my Sasquatch in -15C he told me he didn't know anyone who had but that it was probably going to be fine...so this AM at -21C I had a little time & starting tuning my recently revamped Sasq out to 30m - this winter I've been shooting ILF with a plunger & some Blackmax wood carbon recurve limbs of the identical weight so I pulled out the feathered arrows I'd been using & got on with it.

In short order I had feathers flying off shafts  at launch & on target impact at a ratio of about 1:2. In one short session I learned that Kirk's bamboo R/D LB limbs can put a lot more stress on an arrow shaft than a wood/carbon recurve limb: 15 feathers off vs. 3 when I shot woodies out of the recurve. Love my BlackMax limbs but but wow Kirk, pretty impressive - when will you start up an ILF series for those of us who are canting-challenged & love shooting with a plunger?

BTW I'm guessing that the plunger probably helps minimize launch stress but I'm guessing that feathers off on impact says a lot for speed.

Last time I shot down near that temp I was using tape on my feathers and they were flying off like that.

That's a mite cool for this southerner! Single digits and below are for those with more juice than I have left!

That has to be frustrating, for sure, but I would have to wonder if the effects of super cold would impact point of impact more than to use feathers coming off as an indicator of speed at launch...

As Extrema put it, how they're affixed (feathers) might be a big factor too...

Be interesting to see what impact cold has on point of impact at same yardage with warmer temps...
