I've shot Bear Razor heads an one or two other similar heads for quite a few years,but I'm looking at increasing the size and maybe blade count,but I'd like a bit of feed back from guys that have shot big heads.
The two I'm looking at trying out are the Sasquatch and the Muzzy Phantom.
I'd like to shoot either with the bleeder in the 4 blade format,have no problems getting them scalpel sharp,and currently shoot 50lbs.
Cheers,
ED.

I generally tell guys that 50lbs is about the minimum I'd recommend for the big 1 1/2 inch Snuffers on typical sized game animals.  We've killed lots of animals up to elk sized with bows in that range.  Last fall my father was recovering from rotator cuff surgery and killed several whitetails including a buck in the 250 lb size range with a 42 lb Black Widow recurve and big Snuffers with carbon arrows with exit holes on all of them.

If you're shooting a reasonably efficient setup I would not worry at all about using the heads you mention as far as penetration goes.

I've only shot them out of fairly stout bows 65+#'s I don't think it would be a problem as long as arrow flight is good.You'll have a bit more FOC.I,ve used the big Muzzy with good results.

No problem.

I've shot the big snuffers for many years.  Depending on your arrows, you may have to deal with getting to the correct spine again for good arrow flight.  Aside from that you should benefit from the larger head.

personally, i've found that more and wider razor sharp blades are just fine with most any weight bow as long as you hit the right spot on the animal.    

with that in mind, and knowing your own consistent accuracy at hunting distances and during hunt conditions, with much less than a true 50# holding weight i'd opt for a long 1-1/8" to 1-1/4" twin blade.

Ed,all my bows are around 50 pounds and I've gone the other way. Small broadheads. I use to shoot the 4 blade Phantoms and have taken many deer with them but as Rob says "As long as you hit the right spot" they are fine. Well hunting with any weapon you can not always be guaranteed a perfect shot. That's why I've gone small diameter heads.

I've found that a small 100 grain four blade head gives me much better penetration simply due to less drag as it passes through the animal (in my case whitetails). To make up for the heads light weight I simply add 100 grain brass inserts behind them. I am very pleased with my results now after shooting many more deer with my slimmer configuration.

I use bigger heads with lighter bows but only with heavier arrows.I have no problem at all putting 2" wide treesharks through deer and hogs with 40-45lbs but would not use them on a 350gn arrow.The lighter the arrow the smaller the broadhead is my rule.I will shoot any head made for deer on a 500gn arrow but go to the smaller 3 blades like the woodsman or 4 blade stingers for the light arrows.I always shoot 450gn plus for hog hunting and prefer the big two blade simmons or woodsman over everything else. jmo
