Sierra accidentally produced a great bullet with the TMK, but otherwise could not find its own ass with both hands and the lights on. I’d love to see them wake up and expand, produce and market what they have with the TMK. Everything else they make is 30 to 60 years behind the times. I’ve emailed them suggesting that they should make a 145 gr 6.5, a 105-115 gr 6 mm and an 85-90 gr .224 in the TMK line and ramp up their manufacturing of the rest of the line. Their response was that the bullet was not appropriate for hunting and that those weights were too heavy for most factory twist rates.Sierra is "putting resources mostly towards the most popular offerings, production timelines may be extended for less popular bullet offerings" is what I was told.
