has anyone use the new round ball target they say it works real well just throw it out and shoot but for 70 dollars i was going to ask your thoughts

Are you talking about the Rinehart RFT ball?
It's a terrific target but you need to shop price.

Man, I'd buy a bushel basket of tennis balls before I paid THAT price..:)
They are, BTW, great interactive targets for archers..:) Jim

Best target I've ever seen for field points or especially broadheads has been a big blob of carpet backing. They are heavy but if you can find someone around that makes them the last forever. A shop around here used to have them for 40 bucks. (an absolute steel) They were about 20 inches thick and 30 inches or more in diameter. They looked like a big slice of tree trunk.

Don't know about the round ball, but thought I'd post my 2 cents worth about the worst target I've shot in a while-

It's the Buckmasters target, available in Walmart. I shot a half-dozen Easton Axis FMJ's into one yesterday- took 15 min. to pull my arrows out of it!!

Best, IMHO, is still the Block.
