Well, Tiger, sometimes you get what you wish for. I talked to JD at PTR91, INc. a couple of weeks ago and he told me they are in development of the x39 version. He indicated that magazines were a problem at this point. But they are working on it.
Mine PTR in 308 is a real tack driver, so I asked about other possible versions such as a 22-250. He shied away from that one.
I'd do the 243 but it would burn more powder than I would like and the cost of components is higher generally in 6mm, and to try to find the more expensive 243 brass in the grass would be troublesome. As a handloader that would be a downside.
I've shot the V93 at some distance and achieved good groups. Actually, my girlfriend is the one who got the good groups, not me so much. (ugh). But the platform has demonstrated to me at least the potential for really good accuracy. The 10 shots in one inch she did at 100 meters demonstrated that the rifle has potential. The boolits were the 55 grain Hornady FMJ's, so one must ask what would happen with a dedicated varmit bullet and a more powerful scope than 4x? This is one of many experiments I hope to conduct as time goes by.
Anyways... I digress.
