Ron, I'd like to share this pic with you in regards to my last outing with my CVA 50 cal Optima. I'm shooting your 300 gr Scorpion PT Golds, CRS sabots trimmed to the top of bullet ogive and 70/100 gr of BH209.
I've sighted my Optima in at +3" @100 ..... ZERO at 150 and -7" at 200 yards ..... giving me a 170 yard 6" PBR
My first 3 shots at 100 yards were all touching (1/2 group) and my 4th shot just went a little high but still giving me a sub 1" group.
I then proceeded to shoot another 3 at 200 yards and ended up with about a 3 1/2" group ...... I've actually shot 2 1/2" groups on several other occasions with NO wind.
I've found your CRS sabots to out preform all others no matter what bullets I shoot and decided that the load combination as stated above to be my "GO TO" hunting load this season.
With any luck I'll get to see how it does on my up-coming tip to IL for the late muzzleloader season.
Thanks again for a great product and your companies customer service is to be commended.
