Zwickey No Mercy 2-Blade Screw-In Broadheads 3-pack Review

Yes you should not have an issue there.

They should work for your setup provided you get the right spine arrow. As far as the correct spine, we wold need to know your draw length as well as the type of shaft you want to use (wood, carbon, or aluminum). You can look at our arrow charts http://www.3riversarchery.com/pdf/ArrowCharts.pdf . As for books, the two I would recommend are The Traditional Bowhunter's Handbook (Item# 7015) and Shooting The Stickbow (Item# 7832)

Extreme FOC is emerging in the traditional world as the "right direction", especially versus the "speed to the exclusion of all else" mentality of the compound archery mindset. However, 175grains is a heavy broad head weight for a 40 lb draw bow. It's not impossible, but you will have to be willing to live with a substantial trajectory arc for your setup. As for spine, most charts don't deal with the numbers you're talking about. Spine is determined by three factors, draw length, draw weight and point weight( four if you foray into the compound world )so we 're lacking critical info to be able to even start a conversation about proper spine. I will say this, you'll need substantial control on the back of the arrow in the form of long enough and angled enough fletching to compensate for that extra heavy point. As for aid, nothing beats experience, I'd try to find a trad archery club to get help from locally first, then I'd use the resource available from the 3 Rivers crowd. I don't have a lot of experience with books , I have G. Fred Asbell's books, I'm sure there are plenty of others that will help as well. Good luck. Sent from my iPhone

I think the best advice is to go through a paper tuning process with a number of different weight points and lengths of arrow. There are sets of field points available that contain many different weights. Stephen H. Phillips

Yes it will make sure you get the two blade sharpener.

Never used that brand of sharpener , but i will tell you what i know about sharpening these broad heads , first clean the flat side as flat as you can ..then take metal of the bevel with whatever system you have until you create a burr , steel it carefully with a quality steel until the burr just comes off . if you continue steeling or sharpening you will just blunt he blade . The point should be sharp but after that the first 15 to 20 mm will not shave hair , Dont worry this part is the bit that splits the bone, the double ferral just does not Sharpen !! The remainder of the blade is what i call the working part ! this will shave hair and cause as much bleed out as you could wish for . Let me know how you get on . Jap Hunter (New Zealand)

No, the "CC" Sharpener is for double bevel sharpening. It will not work for single bevel broadheads. Thanx, Ned

1 3/16" is the cutting diameter.

165 LW Z-M, 1.155" diameter, 2.44" edge length. At least, that's the average on mine. YMMV.

These broadheads will come in over weight. They have extra metal on them so that they will be the correct weight after you sharpen them. All of the Zwickey broadheads need to be sharpened before use.

The KME sharpener will work on this broadhead. It will change the bevel angle of the broadhead slightly, though.

It is supposed to be 25 degree. I ended up freehanding it on a file first and finishing on a diamond stone. After the file the edge is wide enough to feel as you sharpen as long as you go slow and easy.

Yes you should not have an issue there.

As long as the Easton Helios has a standard thread count inserts they will fit just fine. If they have a deep six inserts you will need to go with a deep six broadhead.

Unfortunately they do not.

No, they are not too heavy. As long as you get the proper arrow spine, they should be fine.

I don't see a grain weight these for these broad heads..but my advice is always with anything new..specially broad heads...use one as a practice tip into a 3d foam target or anything that a braod head can be easily removed from. No fiber bags. But I don't see why not.most deer shot with traditional equipment is done 15 yards or under. I use something very similar and a swear by them now after making the worst shot in my career..lol   hope I helped..james Sent from Yahoo! Mail on Android

No such thing as "too heavy". As long as your arrow spine is sufficient to handle the weight (165 grns) you can shoot them. They'll be slower by a little than the standard 125grn. but it will be made up in better penetration due to increased momentum. Kevin
