[QUOTE="Okanogan, post: 2561104, member: 90397"] The 300 BO is a fun little cartridge especially if you're running suppressed. I am now down to just a AR pistol which I have suppressed with a TBAC Dominus. You haven't really said much about what your goals are for your soon to be set up. The BO isn't really a long range cartridge so for my uses I'm not looking for the same kind of things I look for when loading my 300 WMs, 6.5 SAUM, or Valkyrie. I'm just looking for plinking, target, defense and maybe deer at fairly short range. For those types of applications, I have found Hornady dies and Lock N Load progressive press save me time and produce satisfactory results. (I still weigh powder charges though) Depending on what your goals are, changing up from your long range reloading practices may save you time and money. Here are a few comments from my 300BO experience that you can take or leave: - CFE Blk has worked well for me for both subs and supers. However, it tends to like to have a compact load which means getting a good combination of charge weight and bullet selection might be a challenge. My favorite subsonic load is a 225g hornady match bullet seated on 12.8g. (The easiest way to determine what is a compact load seating depth is to put the charge in a fired unsized case and measure the COAL with the bullet setting on the charge.) - A1680 is more forgiving on not being compact and so probably makes a better choice for many subsonic loads. - I have used H110 for many of my supersonic loads and I think it will give you a little more velocity than many of the other options. - I have had good luck with starline 300 BO brass. It isn't as soft as Hornady brass. It isn't as good as Lapua and some of the high end mfr but it gets the job done for me at a reasonable price. Normally, I buy direct from Starline but they are apparently so backed up they aren't taking back orders like they normally do. Brownells and Powder Valley both had some available earlier today. - If you're running an AR platform, the 190 Sub-X rounds may have an issue feeding if you seat the bullets deep enough to make a compact subsonic load with CFE Blk so you may want to try a different powder if you're trying to stay subsonic. It sounds like you are fortunate to have small rifle primers readily available. The rest of the components you need are generally available and you should be able to have some fun and save some money over the currently still very high prices for non-FMJ factory ammo. [/QUOTE]
