I will say I am not into modding guns or loading my own rounds, but i would like to get into reloading someday. Anyway, for a stock gun and a quality factory load (I have used Remington accutip rounds in the past. Expensive but they seem to work well) how is this setup: Browning Eclipse M-1000 stainless .300 WSM with a Leupold VX III 6.5-20x50mm LR scope. Also, how heavy of a round should I be shooting? I am thinking a 150gr.? I would like to use this setup to shoot 500+ yards confidently with practice, practice, practice of course. I shoot deer mostly but would like to get into more long range game shooting. Let me know what you guys think, I am by no means an expert so any input would be appreciated.
