When i bought my Z7 the dealer suggested CX Mach 5 350's. They shot nice with field tips but not so great with broadheads. My draw length is 28" and the bow is set at 60lb draw. Arrow length is 27" I recently went to the shop to get new arrows and they were sold out so i went to another shop. Ended up getting the CX Maxima Hunters (what i really wanted in the first place). The guy recommended going to a 250 gr. arrow which i listened bc im new at this. The broadhead flight is unbelievable . Im just wondering if a 250 is okay for that bow? CX website arrow chart shows Maxima 250's for my draw length and weight but EVERYBODY is shooting 350's and 400's. Kinetic energy will be sufficient for white tail deer is my real concern. Thanks
You're good to go. CE 250s are a .400 spine. That is the typical recommendation for a 60 lb setup. My maximas have always flown very well and been very consistent. You'll have no problem at all for whitetail hunting.
What he said! Be careful about spine and "weight". Each manufacturer gives their spine differently. For CX the 250 is an arbitrary number to indicate a shaft spine deflection of .400", this is the proper shaft for your set-up. The same deflection for Easton is a 400 and for PSE is a 200. The industry really needs to improve this as it's one of the most confusing things I see people getting tripped up on. Shaft weight in grains has nothing to do with the spine so when someone mistakenly refers to the "weight" of a shaft, in your case as 250, what they are really talking about is spine. A heavier spine shaft (one with less deflection) will weigh more than a lighter one of the same manufacturer and type. People arbitrarily throw the term "weight" around and a lot of the time it is misused.
This^^I had a hell of a time shoping around for arrows looking at different companies they all have stupid ways to tell you what the spine deflection is. I decided to go with Easton since thier's is what they say it is. The GPI is going to be your arrow wieght. The spine is something completly different try not to get them confused i know i used to. I got alot of advise on this forum when I first started doing my shoping and everyone was telling me I need a 340 spine(they went and looked at the chart) well I went ahead and bought a 340 spine this is before I learned what FOC is. Now I want to put heavy inserts into my arrows and shoot heavy heads but I'm shooting a "speed bow" (Mathews Monster) at 70# so with my 340 spines that I feel I wasted money on I'm not going to put in inserts or shoot heavy heads. I wish I would have taken the time to really understand what I wanted before blowing 250 bucks on a couple dozen arrows. I should have got the 300 spine or maybe found one even higher. Like 280 range. Kodiak what do you think of my current set up? I am going to drop my wieght to 60 and shoot the 340's with 100 grn heads. I think that should be fine for now although I'll have crap for FOC. What would you recomend for my next arrow purchase as far as spine is concerned if i'm going to wieght the tip down as heavy as possible? sorry I think people don't consider the difference between a speed bow and your typical hunting bow. There should be a chart for speed bows and heavy head inserts.
Its like HDTVs and their contrast ratios. They all say 1000000:1 or 2000000000:1 but the 1 is defined by each company diferently. So stupid. But there isnt a law saying you can't up your contrast ratio to make it sound better. Oops I'll shut up now.
