Bullshot, these are the dimensions of the Lyman 410660 that I have.

Hope this helps.

Thank you Tom. Do you think this boolit will stabilize in a 40-65 with a 1-18 twist?
Thanks again

Bullshot,

My experience with the bullet says that it might work OK in the 1-18 twist at the closer ranges or maybe at longer ranges if driven quite fast.

Shooting from a 1-16 twist barrel, I found excellent accuracy at 100 and 200 yards when propelled with duplex loads that kept the bullet above Mach 1 all the way to the target.
At longer ranges there was evidence of tipping on the target and the accuracy deteriorated severely at the longer ranges.

I have yet to try the bullet in the 1:14.5 twist barrel, but my experiences, calculations and gut instinct tell me that if cast fairly hard and launched at over 1200fps, it should do well at the longer ranges.

Thanks for all the info Tom. I'm shooting RCBS 300 CSA with reasonable accuracy. Just looking at other boolits. Any suggestions?
