Bugger have you tried the 110gr Accu Bonds? They work great in both my Roberts and 25/06.
The second load I tested in my wife's Ruger 77 Hawkeye .25-06 using the 110 AB shot into a 3/4" group. Results on deer have been great. I am curious how the Partitions might shoot in it, but don't see anything to be gained.
Accubonds are great. Hard to go wrong. I’d go with what shot best.
Bugger, you may try a few of these 115 NPT’s as they’re reportedly shorter than standard. Who knows. Price is right.
