Next year I think I will give them a go 190 lrht or the 220 lrht to see. I have both bulletsI was curious how it would effect performance as well, however (my guess as well as a few other individuals) the empty cavity behind the hollow point seems to make them perform properly, I think the copper nose crushes in and then essentially the bullet begins to act like a standard exposed lead tipped spire point bullet, mushrooming/fragmenting as it goes through.
