Just ordered six of these. I am switching from victory HVs so I know they are going to be considerably slower, but I am looking to gain some KE. How much pin adjustment do you think will be needed? People who shoot them, are you happy with them?
They were suggested to me by a friend who buys them by the dozen. He claims they shoot great. I had already fallen for the Maxima Hunters which I love. Not sure for the adjustment depends on the previous weight of your HV's, I didnt look them up.
I just shot my first buck of the year with them today! 30yd double lung complete pass through...simply beautiful! You will have to adjust your sights...down...If I looked at the correct arrows your arrows are very light...in the 6.0-7.0gpi range..whats your draw weight?. Pile drivers run 10.4 gpi for the 250's and 11.3 gpi for the 350's. I like a heavier arrow..more KE (like what your looking for) and it helps quiet your bow! I'm shooting about 76ft/lbs of KE which is plenty!
I shoot the 250's, and they're an ok arrow. I can't get the FOC I'd like without going 500+grain total weight, which is a little heavier than I'd like. Once I shoot through them I'm going back to Easton. They are heavy and accurate, and would most likely work good for you. When I switched from my Axis 340's the pin adjustment was very, very slight.
I am pulling 70lbs. You are correct about the gpi of my old arrows. I did not want a light arrow they are what the pro-shop owner told me I wanted. I made the best of the situation and opted to use a cut-on-contact head with good results. Now that I have shot through those arrows I decided to go for the KE route. Based off of the charts I ordered the 350's. I had them cut the arrows at 28in and my draw is 29in.
Whats your bow's IBO?...regardless you'll get plenty of KE with that set up! You shouldn't have to move your sights too much...like I said before hopefully and most likely just down!
KE is based on speed, you'll gain plenty of momentum which will help you tons. The way the equations are written, in KE, velocity is squared so your KE will increase more greatly based upon speed. As you lower your speed, you will lower your KE. Momentum is just the opposite, it puts more of a basis on weight. Think of it as this... a car will have more KE immediately before a crash, and a frieght train will have more momentum. The goal is therefore to get an arrow setup similar to a bullet train, a tradeoff between speed and momentum. 11.3 gpi is a little heavy for my taste however, to each his own, carbon express makes some good arrows, I love my maximas. Easton full metal jackets are the same concept, maybe you can look into those as well. Some people on here love the heavier arrows and swear by them. I'm sure they'll work great and be some reliable arrows. I would definitely retune your bow from scratch. It's just better to be on teh safe side.
Thanks for the input guys. I had planned to broadhead tune and bareshaft tune when they get here, I was just curious to get input from others about what I could expect in speed difference with such a drastic wheight change.
There's a loose rule of 3 grains per foot. Meaning that if you add 3 grains to your arrow, you'll lose 1 fps. It will at least give you a ballpark figure.
