I reload for two .223 One is a Tikka with a custom barrel using 50gr V Max loaded with 25.1gr of N133 the other an RWS factory using 50 gr Nosler BT with 25.3gr of N133 also.
Teaching probably to the converted but best to refer to the Vhitavuori web site and consider doing the OCW method in say .2gr increments.
