I had the opportunity to shoot this a little today. I have a 4- cavity PB mould. I shoot a lot of cast bullet loads in the 16-1800fps ballpark in my .30- cal rifles. These loads are easy on the shoulder, yet are more resistant to wind drift at my typical 100m distance than low-node PB lubed bullet loads. PC allows me to drive PB bullets in this velocity window, and it saves me the labour of making/ installing gas checks.
Previously, I’ve found PB/PC bullets in this weight range tend to shoot well with 20grs Vihta N110 in the .30-06. I loaded 15 rounds, with bullets that «survived» the mould break-in. I admit to some leniency in the bullet sorting process, there were some minor flaws.
I fired 3 5-shot groups from a bench using my Scultz& Larsen .30-06 hunting rifle, wearing a 2.2-9x scope, and a suppressor. It resulted in 3 nice groups, averaging 1MOA. I’ll run them over the Magnetospeed later, should be about 1700 fps.
I’m very happy so far, good start!
