Weedhopper, in answer to your question my .45 is a thompson center black diamond XR. I use powerbelt aero tips in 195g and 150g of pyrodex pellets. I have a 10 power simmons scope. The gun shoots great that far out with the 195's but if I go heavyer the groups seem to open up a bit. My group also all have H-R 12 gauge shotguns that we use the winchestor platnum tips with great accuracy out to 150yrds. You just have to sight them in for that range and also practise at 50yards to know were you will hit. The slug will be a lot higher at 50. The accuracy we get is from alot of time at the range, shooting all year long.
