Home Forums Reloading Big Game Rifles GMX vs TSX Comparison

I attributed reduced TSX velocity mostly to the increased COL which increases case capacity at ignition and for this rifle, there is still some freebore. I wonder why Hornady uses the same COL for monolithic GMX, bonded Interbond, and lead cup and core SST.

This rifle has much better precision with 150 monolithic and 165 SST because of its 1:12 twist (I think) compared with my single shot Merkel K3 (1:10 twist) which shoots 165 monolithic and 180 gr cup and core (NBT, AB, SST) with better precision. The lengths of the 150 mono & 165 lead are very close as are the lengths of the 165 mono and 180 lead.
