Ok so Im new to reloading. Took my first batch out to the range today. 110 grain S & B FMJ. Hornaday brass. BR-4 primers. My question is the charge weight. I used the chart from Accurate Arms for Hornady V max load. Loaded to 28.3 grains of 2200 COAL of 2.23. No pressure signs. Is it safe to go hotter? I have a bison barrel with their 6.8 chamber.
