The only LPP that I load is for 45 ACP, all others are SPP. Any reason other than range brass is easier to find in LPP to not start loading 45's using SPP ? I already have about 500 SPP brass and can get another 1000 for 50.00. I loaded up 50 of them and did not notice any difference in them. Reason for changing is I am lazy and load on a Dillon 550 and caliber changes would be a lot easier (remember, I'm lazy).
