This table was constructed using a ballistic program named "Balistic" by a fellow named "Frenchu". Here's the same data as a graph: 35
I just have to study these tables and graphs for a while before I see what's going on. Bullets have LESS wind drift at 1100 fps than at higher velocities. As velocity is increased, wind drift increases. Then as velocity goes above 1300-1500 F/s, wind drift again decreases. This is counter-intuitive, but it is true. Unfortunately, wind drift is highest at 1300 fps to 1500 fps, the middle of the low speed cast bullet velocities. We can reduce wind drift by either increasing or decreasing muzzle velocity or by increasing the BC of the bullet. The most feasible options seem to be either reducing muzzle velocity or increasing the BC of the bullet or both. The easiest and cheapest option is to reduce the velocity of the bullet by reducing the powder charge. Reducing the powder charge sometimes/often increases variation in MV because the powder takes up less of the space in the case, and reduces accuracy. One way to reduce MV variation in light charges is to use a wad to hold the powder in place against the primer. See "ON WADS <strong>AND</strong> FILLERS" for a discussion of the possible risks of using wads. Bullet drop, with BC above ~.3, isn't sensitive to BC. A rule of thumb that I've developed is: Bullets of the same length and same shape have about the same BC, regardless of caliber". A 1" long 22-caliber bullet has about the same BC as a 1" long 30-caliber bullet. Another rule I've developed is: "Don't worry about BC". It's nice to know about, and some of the more/most advanced cast bullet shooters take it into consideration, but for the majority of us it shouldn't be a concern. Thoughts on Throats, Leades, Ball Seats and Bullet fit Ric Bowman A lead alloy bullet has a hard life. It is not strong nor does it have a hard copper jacket. It gets mushed by a heavy gas check or a wall of high temperature gas in the butt. It has a hard steel wall that confines it and a column of air holding it back. Then the lands grab it and make it twist around its center of form. No, an alloy bullet doesn’t have an easy life. The ideal position for the bullet is this: the nose is snugly resting on the top of the lands and the front driving band is snug against the leade with its circumference is exactly the same as the diameter of the throat. The rest of the bullet is contained in the neck of the case that is perfectly centered in the perfectly centered chamber. The case mouth touches the front of the chamber so that a smooth surface exists from the base of the bullet through the throat, leade and bore. There is no gap between the front of the case mouth and the throat, there is no gravity, ejector or extractor tension to keep the resized case from laying perfectly concentric to the bore center line. Yeah, when pigs fly and I’m a young man again! Terms as I use them, whether they are technically correct or not: Chamber - The interior portion of the barrel that surrounds the brass case. Throat – The parallel section of the bore in front of the chamber before the lands of the rifling begins. Leade – The section of the bore in which the lands of the rifling rise up from the throat into the rifled bore proper. Ball seat – A type of throat/leade combination that is made with a one- or two-angle cut from the front of the chamber to the bore proper. 36
