I have loaded the 45,53,62 and 70.
I had a 1:7 and a 1:9 twist.
The heaviest bullet I could get to tighten up in the 1:9 twist was the 53 grain bullet.
The 62 just shot sloppy in my rifle. Probably about 1.5" or so.
Others mileage might vary.
I think I chronographed them too, but I lost that notebook.
I shot them over H4895.
I think my max load was 24.5 gr for the 62. That is what I have in the saved quickload file.
Barnes lists a max load of 25.5 gr of varget.
Both the 62 and 70 did fine in the 1:7 twist.
