"WOW" I just had a chance to shoot my Hornady FTX .458" 325gr reloads out of my 22" barreled T/C Contender 45-70 carbine and to say that I am happy with their performance so far is an understatement.
Average velocity was 1897fps to 1917fps and the first 3 shots @ 50 yards were 2 1/2" high and made one ragged hole I next set up at 100 yards and with my old eyes and only a Vari X 11 1-4X Leupold scope on 4X grouped just over 1 1/2" - 2" max and they were still 2 1/2" high.
Did my normal hold over top of the duplex post dead on the 210 meter gong that normally hits appr 2" high and hit way over the gong aimed 1/2 way between the reticule and the post hit dead on so they definately fly flatter than a flat nose 300gr bullet.
Thinking I need a higher magnification 2.5- 8X Boone & Crocket or 2-7 Compact LR reticule scope to take advantage of the flatter tragectory should be able to pop deer this fall out to 250 - 300 yards that is if I can pry my hands off my other T/C Contender carbine in 375JDJ...
