Hi All, I just made the jump into reloading, and purchased all my equipment and am excited to get started. I have spent a lot of the day watching videos and reading articles, and like everything else, every has a different opinion. Some of these questions may have been answered elsewhere in the thread, so bear with me..I'm new at this. For reference, I shoot a .300 Win Mag Sendero. Keep in mind also that I am not a long range match shooter, but a hunter that wants the most accuracy out of his rifle to cover those western mountain shots. Brass brand: Does different brands matter when it comes to reloading? Im assuming certain brands come in different thicknesses, so does that mean I would have to adjust a powder charge to work within that brass, or does it not matter that much? Concentricity Gauge: I've watched a few vids where guys will use these to determine the thick side of the case all, and use that to index their shells at 12 o'clock (or depending on how many lugs your gun has). Is that an essential practice? Distance off Lans: When building rounds to test, how are you determining how far off the lans the bullet is seated, or how do you seat your rounds to test this? Determining charge: Do you start with the minimum listed charge and add XX amount of grains up to the max listed? Do you go past that max listing? Seating the Dies: This is a bit of a noob questions, but when you are setting up the neck sizing die, and you are supposed to bottom it out against the ram, back the ram off, and turn the die 1/8 to 1/4 past that point and lock it down, does it matter whether its 1/8 or 1/4? I want to make sure im turning it enough. On a side note, has anyone loading the Barnes LRX rounds and have an opinion? Do you load those to the same specs as the TSX round? Thanks Everyone!
