I'm loading some 183 HPBT Sierras for a 284 winchester. Following an older post I found in here I loaded in increments between 51.5gr (2770 fps) of H4350 and 52.3gr (2823 fps) of H 4350 out of a 8.5 twist barrel. Now I'm not an expert and this is actually my first time fine tuning a load although I've been reloading for a few years. But based on what I could see there was no high pressure signs, should I keep raising the increments until I see some high pressure signs or is that not necessarily going to create the best bullet for my gun? I suppose the sweet spot for an individual gun is not always found with more velocity? I did call Sierra yesterday and they told me there is currently no data for this round, even though it is a few years old. Thanks in advance fellas.
