As of recently I begain testing on my 7 twist 22 dasher. I wanted to use the new Berger 90 grain VLDs. I finally worked up a load for top accuracy and speed. The top loads were a little slower than expected. My Load is rem 7.5 primer and 36.8 grains of ramshot hunter for 3100 fps. I easily got 3000 fps with my last barrel with the 100 grain wildcats. I think the B.C between the 90 grain vld and wildcat RBBT will be very close. Useing the 100 grain wildcats for my drop charts i found them to have a b.c close to .525 so if the bergers b.c is right at .517 i will be very happy. Just figured I'd post this figured someone might be interested.
