For testing to see if this grand experiment had been worth the effort I set up a 200 yd target and set about some ladder tests with numerous bullets. A 10 charge weight incremental test gives a great deal of information and is the cheapest way to find the best bullet for this barrel. Fortunately one of the outlets here sells a 15 bullet sample pack so this was a good way to go. I tested a range of powders and bullets from the 100gn ttsx to the 130gn sierra but the 123gn A Max was the stunning outright winner with CFE 223 powder and CCI mag primers. I have since gone to the SST with the same results.
