shinz,

Thanks for the idea, I'll give it a try.
Managed to get a good set of data for the CBE "paradox" projectiles, they chronograph at just a shade under 1400 fps with some AP-100 powder, bullet weighs 780 grains from my lead, which is about like wheel weights with a little lino, might be a bit hard for this calibre, but I was making rifle projectiles at the same time and decided to cast a few 12 bores while the pot was going. Sure drains the lead in a hurry though. I've had the best luck with filling the big groove in the projectile with lube, not exactly "pucka" but it works for me and stops the leading much better than liquid alox does. This rifle has taken just on 240 rounds to get the loads worked out to what I expect, which is 5 shot groups at 100 metres under 3 inches with the open sights, might have been a bit ambitious looking back now, but it has worked out OK for me.
And besides, what is more fun than shooting such a fun firearm, any excuse will do me!

Regards,
David.
