I'll shoot a cva optima with shorter barrel (26"). I figured it would be best to alternate each shot vs shooting 5 of one and then the other. Probably will have cooler temps 8:30am tomorrow so the barrel temp should stay consistant. I'll use 777 primer and crushed ribbed sabot.

I guess I figured 25% difference in weight would make a bigger difference. I am looking forward to the experience. On your recommendation of the speer, is why I ordered them. I meant to order the speers in 300g but had a senior moment and didn't pay attention. I do have some 300g on order.
