This is the first spring that guys have been shooting the 10s, but indications are that they will probably end up being the optimal size for the .410.

If I told you one of the feed-back reports I got about shooting them (in a 20 ga), you'd say the guy or I was lying, so I won't share it.

But the math indicates 50 yd plus penetration energy and with the extra pellet count, guys are getting bonafide patterns to about that distance. So, no excess either way.
