I wouldnt bother building a load for 20 projectiles none will be left by the time load dev is done

I used ballistic tips for a long time at sub speed and they work great as skull crackers but they were pretty expensive for essentially FMJ performance as you could damn near reuse any bullets you recover

Yep hoping to roll the dice on load dev and get double sixes first roll, if not then we get some more projectiles and do it the traditional way.

These are for the annual homekill of a tame steer on a lifestyle block. The problem the last two years is that the cattle have somehow had an awareness of what is about to occur and gone from tame to gate wreckers as soon as a stranger with a rifle gets within half a kilometre of the property.
The load only needs to be accurate enough for 15m shot. If I get it right I just need three to prove stability and subsonic velocity and then three more to check POI with suppressor in place. That will leave enough for >a decade of homekill.
