Thread: Who still makes 0.223" diameter projectiles?

I reload this cartridge, also in a Bars. I have a couple of comments;

1. A 55 gr projectile is too long for the slow twist. The original bullet was a very short blunt nosed projectile. I suggest a 40gr flat base bullet.

2. .224 could cause high pressure, .221 is the correct diameter - I resize mine with a push-through die from CH Tool and Die.

3. I suggest a faster powder - AR2207 or BM2. I started with 23gr 2207. At 25gr there were definite pressure signs.

I was sub 1 inch at 50m, but still need to do more development. The cartridge has potential.
