I got my FMJ's today they seem so fast! The first one blewfletching deep into the middle of mynew Gander Mountain block from 35 yards. Needless to say this rippled my virgin vanes[:'(]. This is from my "old" 05 Alley. Shooting Beamans, (which I did side by side), they only sunk in half-way to the fletching at the same distance. Granted the FMJ's feel slipperier and pull easier is that what I was seeing?

What the heck kind of targets do you guys shoot at with these 320+ fps bows.

Block is rated up to 400 FPS

You saw my bow/arrow shoot GR8, needless to say I ruin targets with it. My 3D targets have holes blown out the back side.

The plus is I'm shooting a light arrow for 3D but just ordered some 2413's to set up for hunting, the should pound the targets. I'm anxious to see what they do to the targets. I know I about knocked a turkey off it's perch in the Harrisburg shoot.

Yeah mine too..from over use more than anything. Thats why I picked up the new Block knock-off from Gander mountain. Heck I could throw an arrow through my original block or my 3d Deer. As a side note does that crack filling foam really work on 3d targets? I've heard many, say it does.

Actually it does work. It's not like it's new but it does work.

I have the Block knock off too. My ACC's burry to the vanes depending on which bow I shoot it out of.

its not the speed with the fmj its the kinetic energy because of the weight of the arrow

It weighs .4 grains/inch more than I was shooting [>:]

KE out of the same bow, different weights doesn't change. Must be momentum.

I've run my own test with the fmj and my results were not impressive. Which beman were you using? Last I looked the mfx was the same as an fmj and an ics is almost 2 grains lighter. As far as slippery the bemans I'd say are the slipperest one's out there.

I've also shot arrows of different weights and the moderate one's with good ke and speed sunk the deepest, a full 3"s deeper. They were close to 120 grns lighter than the heaviest which was 560. All test are done with 1 3/16" fixed blade broadheads.

One factor that does change things is diameter and the fmj is small compared to the beman.The insert difference isone reason they pulled easier.

I use a solid block. I think the gander one is layered. Solid ones aren't for points.

I think they do make a little difference, I did notice that going to a smaller diameter arrow but keeping about the same exact weight, Ive increased a few fps. I was shooting Easton 2314s now Shooting the Easton Carbon Excel St's 400's I never had to adjust anythign on my bow which I found to be a good thing. The aluminums and carbons are shooting the same but the carbons seem to be a little more flatter and faster. Maybe its just me. I think I run each one through a chrono and see what I get.
