BULLET/BARREL TWIST REFERENCE
NOTES:
1. Email any comments, feel free to supply missing data or correct errors.
2. Higher velocity rifles require less twist at short range; data assumes shooter requires long range stability
3. Bullets that are long for weight (eg VLD, boatail spitzer, nylon tip), use next faster twist.
