Re: Best 22 tac trainer?
IMHO, the goal of a trainer is to be durable, reliable, consistent, and make the training process cheaper. Yes, a really nice hammer can drive the nail, but so can a bargain Stanley from WallyWorld. In the training process, quantity (of rounds fired) is at least as important as quality. Less buckage spent on the rifle allows more spent on the ammo. The trainer is a tool, not a trophy.
I'd keep it simple and frugal. I'd step back from the accuracy hangup and set my goals on consistent performance, and try for consistent improvement. The important thing to do is to rule out the equipment as the source of flyers. I use a very old, very basic Savage MKII that is probably equivalent to the current MKII-F, but has a receiver that's grooved for a scope, and of course, the pre-Accue-Trigger. It throws me no surprises. The sporter weight barrel likes CCI blue box Standard Velocity Target ammo, and is a bargain.
More than this is neither necessary, nor perhaps even desirable.
