Friend uses them and they seem to work great on reds and goats.

Yes they are great on deer, the base of the projectile is 4mm thick copper and is often found just under the hide on the far side.

40 NBT is exceptional on roos and pretty good on goats, taken the odd fallow with it too with pretty convincing results.

3800fps

Admittedly from a 24" tube though..

Am fairly sure the 40g nbt has the same thick copper base

You're correct on that.. just like your experiences with the 60g, have found the base under the offside skin on more than one occasion.

Their stubby lil ogive often makes them exceptionally accurate

The velocity loss is of little concern to me for a bush hunting rifle. I've shot plenty of animals with .22wmr, .22hornets, .222 and .223.

Cutting a .223 barrel down will reduce the velocity down to approximately .222 velocities...and this is a proven killer on deer, so in my mind there's no issues providing sensible kill shots are taken.
