Figured you would say that. From www.bulletproofme.com Why we Recommend Ceramic Rifle Plates OVER Steel Steel is less expensive than Ceramic, and can take abuse that would significantly degrade a Ceramic Rifle Plate – but still we recommend Ceramic because:
1. Ceramic is better protection - stops Level IV armor piercing threats - better than Level III FMJ or lead-core bullet threats. 2. Ceramic is lighter. 3. Ceramic is Triple Curved to hug the body more closely than single-curved Steel. 4. Steel is much more likely to cause bullet splatter, or, more seriously, ricochet, than Ceramic. (Of course, you'd probably rather take a chance on a ricochet hit, than a guaranteed hit to the body!)
Frankly, unless you are on a VERY tight budget, we recommend Ceramic over Steel to minimize the risk from bullet splatter or ricochet. Even if you put the Extra-Thick Line-X Coating, or a Spall Cover on Steel to reduce bullet splatter, you still have not solved the ricochet problem.
How does ceramic handle getting hit by 7.6x51 or 7.62x39 three times? I would think steel has the advantage there.
