I want to be able to shoot targets at 100 yards. What caliber and minimum FPS would work well for this? Are heavier pellets better?
That is what works for me. I have a death ray Royale 400 out to 90 yards but past that it starts to loose its edge, then the 25's I have take over.
But 25 LBT cast slugs fly much better out of an air gun at uber ranges if you do your homework.
I did some maintainence on my 150 yard target this morning and found these 25 LBT cast bullets between the plywood and the wooden post. They had passed thru two metal plates 1/2 inch of plywood and were imbedded 3/8 of an inch into the post.
They have 77 FPE remaining at 150 yards compared to a 25 ACP's 62 FPE at the muzzle. The group they went into at 150 yards was 2.15 inches fired from a 17 inch unchoked AirForce barrel and a 2x7 Burris scope.
