Spikes Tactical 22 conversion kit

I just got in my Spike's Tactical 22 conversion kit today. I headed out to the range this afternoon to give it a bit of a workout. It ran pretty well on Federal Champion 40 grain solids. I shot 75 rounds with two different magazines and had around 5-6 failures to eject. I believe this is likely to be a break in problem. I'll feel better once I've run a couple hundred rounds through it.

I had some Remington 36 grain hollow points which are not recommended as they are oversized. These were no exception. They would not chamber without repeatedly pulling and releasing the bolt, essentially hammering the round into the chamber. I got two to chamber and fire but decided life was too short to continue with them.

I have the rifle sighted in at 34 years to approximate a 300 yard zero with my 55 grain loads. I set up a target there to check the 22 LR accuracy and was not terribly impressed. I fired around 25 rounds and got a group around 3-4 inches in diameter. I'll have to measure it and see what it really was.

I'd like to get a dedicated 22 LR upper but for right now, the conversion kit seems to be a better investment, ~$245 delivered with two magazines vs. $630 plus shipping for the upper.
