[QUOTE="yorke-1, post: 2036436, member: 11960"] An unmodified 500 Nitro Express (3.00" version) case only holds about 145-150gr of H20, depending on your source. Necking it down and trimming it 2.850", the length of a 300 RUM case, is going to reduce that capacity no matter what the shoulder angle or case taper is. It looks like the 300 VODKA has at least a .300" neck, so if you neck down a 500 Nitro, give it a 40° shoulder, minimum case taper, and a .300" neck you give up a lot of that 145-150gr capacity of the parent case. Now adjust for the different internal case web dimensions for a rimless case and you'd be in the 135-140gr capacity range. That's still plenty of powder space to get some impressive numbers, but it's not like this is a massive case or anything. It's a cool design, but nothing groundbreaking or unheard of before. [/QUOTE]
