Do any of you have experience with a .25 Marauder? Since pellets do not mushroom like .22 LRs on impact it may be better to use a larger round. Just wondering if it makes that big a difference on lethality and also if trajectory is suitable for gray squirrels. Most of the time range is under 40 yd, but as someone pointed out it needs to be precise as the kill zone is very small. I have been thinking about one for sometime, just have not talked myself into it because of the hassle of supplying air to a PCP. It may be necessary however, especially if the .22 SSP is not sufficient.
