YEs it matters, one reason the Lee is almost useless IMO. OAl will varu depending on length of the bullet. Mot JHP will be longer than most FMJ of the same wt. The lead from the HP has to go someplace. Then some bulelts have short bearing surfaces & others longer. So yes, bullet type matters. Not so much w/ stqarting data, but once you start pushing the top, everything matters.
USe starting data or just above & load to the longest OAL your gun will accept. Then work the load up in 0.1gr incremements until you have a load that is doing what you want.
"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".
