As of today, 4/21/09, we are accepting orders for the new BIB 108 Gr. Boat-Tail 6mm bullet: Calculated (G1) BC  – .543;  Calculated (G7) BC – .256.  Ideal twist rate 1 turn in 8.3 inches – produces Sg 1.5 at sea-level, Std. conditions; Sg with 1:8.5″ twist is a very good Sg 1.4.

 Though the G7 model calculates LOWER BC numbers, the figures are relative only to the G7 model: those with exterior ballistics programs featuring the G7 model will find using this model a closer fit over a variety of velocities – an excellent option for 600 – 1,000 Yd. calculations. The excellent JBM Small Arms Ballistics web-site - http://www.jbmballistics.com/cgi-bin/jbmdrag-5.0.cgi - offers the option of both the G1 and G7, as well as other models.

The BIB 6mm, 108 Gr. BT features a [tangent] 11 caliber ogive, 0.052″ meplat diameter, and a 12 degree x 0.082″ long (abbreviated) BT – this bullet will prove easy to tune. Thus far, real world testing suggests an actual BC of about .52, as opposed to the calculated .54.

This BIB offering is priced at $320.00 per 1,000, plus shipping: minimum order, priced at the decimal rate, plus shipping, is 250 each. Please call with your order: 515-438-4010.
