MAybe, if you use all the same headstamp & heavy enough charge wts that a double registers. IME, like 100Krds of 45acp worth, you can't verify a dbl w/ small charges under 5gr w/ any reliabilty. It's a false sense of security. Take a popular TG load, 4gr. Bullets can be off 1/2gr, cases can vary buy 2-3gr, even in the same manuf. So now you are looking for 4gr diff w/ 3.5gr variation, not gonna happen.
"Given adequate penetration, a larger diameter bullet will have an edge in wounding effectiveness. It will damage a blood vessel the smaller projectile barely misses. The larger permanent cavity may lead to faster blood loss. Although such an edge clearly exists, its significance cannot be quantified".
