The state of PA has relaxed the round
ball law for the 2000 blackpowder season. We are in the process of testing slow
twist barrels in both .50 and .54 calibers to come up with a conical that will
shoot accurately in 1:66" and 1:60" twist barrels. We already make
conicals that will shoot fine in the 1:48" twist and faster barrels.
The table below is the projected sizes for these bullets. Our testing should be completed by the end of July and we will plug in the exact weights at that time.
If any of you PA shooters wish to help out, please call our toll free order line for a substantial discount for those willing to help in our test process.
Update 7/19/00
Our testing is complete and these sizes are the production sizes. We thank all our testers for their speedy and thorough work.
For those who may still question the value of a conical bullet over a round ball, we offer the following comparison ballistic data. Experts agree that 800 foot pounds is the minimum energy required to humanely harvest White-tailed Deer. I believe that the table speaks for itself.
