As far as the cost of the HST's, once I completely finish reliability testing and purchase a stockpile, I'll find a cheaper practice round.
I read this entire thread but it's been awhile, and you may have covered this already, but did you test the HST vs. the HST +P? Which do you prefer?
I had planned to use the HST, but when I tested both, I was a little more accurate with the +P. My theory is that the bullet went downrange quicker and thus any bad shooting habits of mine had less time to affect the path of the bullet.
What do you think? I suppose +P's will wear the spring a little more, but I don't shoot a lot right now. I'm trying to buy as many supplies (guns and bullets) before the election. What's your opinion on the HST standard pressure vs. the HST +P?
