The points I dropped were on the simplest of targets, three wounds on one easy target alone. Strange, but overall very pleased. The Supra and my 305gn Carbon Ones did the business.
I found that estimating distance is easier if I try and find a halfway point and then ground walk up to the halfway point, double it and add a few metres for luck! The bow is pushing the arrows out at 293fps so there is plenty of speed to handle any small errors.
I also had a nice surprise in the form of a certificate from the EFAA saying that I had equalled the national record for the EFAA Marked Big Game round as the EFAA 3D Champs (max score of 560/560).
P.S. I shot a 30m Frostbite round a few weeks ago, my first "target" round for well over a year. Put in a 356, quite pleased with that considering!
