Sorry, I know it's not the best thing to be new on a forum and ask a Q as my very first post....but I'm kinda desperate.
Hi y'all,
I have been adviced to use H335 when reloading for a T/CA Contender G2 in 7mmTCU, because it would give superior accuracy. I have the 2000-edition of the Contender Reloading Manual, and on page 147 it lists data for the 150gr Sierra HPBT. I chose a mild load of 26.1 grains, which promised to yield about 1700fps (maximium load was stated to be 27.2 grains).
After loading 5 cartridges I recalled that powder tables change a bit in time, so I decided to check the Hodgdon website for the most recent data on 7mmTCU/H335. I was puzzled that I couldn't find any data for bullets heavier than 139 grains.
Furthermore, I noticed that the listed maximum load for that 139 grain bullet was 26 grains of H335...and I am using a heavier bullet. After a search on the internet I found a post on a messageboard, in which somebody said when getting 2000+ fps, some guy was using more than 23 grains...which suggests that that would be the maximum load.
I have two questions:
1. Does any of you have H335 load data for bullets heavier than 139 grains? I would be particularly interested in data for the Sierra 150gr HPBT and the 160gr SPBT.
2. Is the Thompson/Center reloading manual dangerously wrong, and should I pull the bullets of the 5 cartridges I reloaded?
