Bullet-Making — Even a Novice can Produce Winners

Forum regular Al Nyhus has recently tried his hand at bullet making, producing custom 30-caliber projectiles for his 30 BR match rifles. With help and guidance from his “guru”, bullet-smith Randy Robinett, Al has produced some very impressive bullets. This demonstrates that with patience, determination, and the right tools and components, amazing results are possible, even for a novice bullet-maker.

Al writes: “Thought I’d post some updated info on my 30 Caliber bullet making adventure. It’s been a lot of fun and a real learning experience. I’d like to thank Randy Robinett for all his patient teaching and guidance. The bullets have been working well in competition, being used in the Varmint for Score portion of the IBS Wisconsin State Two Gun Championship win a few weeks back.

Nyhus 30 BR bullets

Here are two photos from recent testing. In the 100-yard, 15-round target, the wind velocity was purposely ignored and the group was fired only with the same flag angle, trying to determine how they worked in the wind. Winds were 12-18 mph from 4 o’clock.

This 200-yard group was fired in near perfect test conditions — overcast, early in the morning, with no mirage. We usually have a small window of what I call ‘Happy Hour’ before the winds crank up.” NOTE: Al’s 30 BR rifle was smithed by Stan Ware of SGR Custom Rifles.

Measuring Group Size
Note how Al measures his groups. Look at the top photo. You’ll see Al starts with the extreme outside edge of the hole, including the gray edge or ring. Then Al subtracts .290″, the TRUE size of one bullet-hole in the paper, as opposed to .308″, the nominal bullet diameter. If you simply subtract a full bullet diameter you will get a smaller number for your group size. That is good for the shooter’s ego, but Al’s method is more accurate because a bullet normally will cut a hole that is smaller than the actual bullet diameter.

New Sinclair High Power Log Book

Sinclair Int’l has a new 150-page competition log book with many smart features. You’ll like the way the book is designed and organized. There are 30 plot sheets for each position; that’s enough for 30 complete 80-round matches. Target sheets (grid-lined in 1 MOA squares) are printed as large as possible for plotting hits. The target sheets are also color-coded for each stage — 200-yard slow fire standing, 200 yard sitting rapid, 300-yard prone rapid, and 600-yard prone slow fire. The book even includes MOA windage charts for commonly used cartridge/bullets with elevation come-ups out to 600 yards.
