Agree with rsbhunter's explanation and others that said you DO NOT NEED new equipment to bump shoulders back. Your full length die already does that. Just adjust it correctly. You are reading too much garbage and obviously confusing yourself. It doesn't sound like you are a competitive shooter so you don't need all the super expensive equipment these forums keep pushing. If it fits in your rifle easily, that's all you need and your rifle will still shoot accurately enough for inside 500 yards. If you want to spend lots of money chasing small groups and shooting 1000+ yards (which is what this forum is about), then you can worry about how much you're bumping, what's your tall target doing, etc, etc, etc. Don't over think this stuff.
