Your experiences with the polymag

Hey,
I have been looking for a little heavier pellet then my 14.3 grns for the infestation of Jack rabbits nipping my young trees in half. I have a benjamin discovery .22 and am curious to know how well these pellets work (accuracy wise) for you. These pellets have held my attention for a while and I think they would work great for my uses if they have decent accuracy. Yes I am aware of the fact that it depends on the gun whether it shoots these well or not.
 
I like the sound of the 16gr polymag it hits with a POP, It does a lot more damage to the pest than the 18gr JSB , Not sure why as I have dug a few pellets out that have hit bone and they do not seem to expand more than the JSB pellet,
But, and there is the But, they drop the pest better and cleaner than the JSB?
I shoot the 22 16 gr Polymag out of my 22 Mutant just because I had about ten tins and the mutant seemed to like them,
My 22 Cricket did not like them that much as my targets are sparrows and Euro doves at 48 yards just to many flyers with the cricket.
I have shot a few cotton tail rabbits and even with a head shot it sounds like a gut shot,
Its just a POP sound.

These are shot at 30 yards. I'll use Hunter Extremes out to 30 but I don't use anything other than JSB Exacts or Air Arms for beyond that.

6-9 are .177 JSB Exacts, Polymag, JSB Ultrashock, and H&N Hunter Extreme
11 - 15 are .22 of the same pellets in the same order. The one pellet by itself on 15 is my fault.

The .22 Polymags are so far off the target I hard to circle them to show where they went.

They're basically hollow points with the pointy tip for a bit more penetration than you might otherwise have from an HP. It also helps with aerodynamics, so they're better at medium ranges HPs.

The massive internal damage, despite not too much expansion is probably due to them tumbling after they hit something hard. I noticed my Supermag wadcutters tumble after they enter the animal. When they clip a bone, they tumble. When a dome clips a bone, it just kind of pushes it to the side a little; maybe breaking it, and continues on through. But they don't ricochet violently off bone and tear up internal organs like wadcutters, HPs, and Polymags do.

Bottom line is that they're expensive, but you only have to buy a tin of 200 to find out if they group. If they DO group in your gun, you can pretty much be assured of their effectiveness at short and medium ranges. (and long range depends on your definition; they won't do 100+ yards like domes will, but 40 or 50 is probably OK, if there's enough energy left in them from your gun)
 
SmaugI've also read that when Polymags are recovered from the target, the tip separates 100% of the time. One more chunk of debris floating around inside the animal can't be good for them!


Lol!! You are supposed to kill an animal when you shoot it. If it is dead, it probably doesn't care. Also, out of a suitably powered airgun, the pellet usually passes clean thru.
