45 colt 230gr Bear Creek Accuracy concerns

[Pmringer]

Hey everyone,

I have been loading some 230gr Bear Creek moly coated round nose in Starline brass with 7.0gr of Universal under it and have been having horrible consistency with accuracy. I know this is a light projectile and typically used for 45 auto but a shooting buddy has had good results and they were available in the local shop. I have been measuring my powder loads, OAL, and checking my crimps almost compulsively. I have been having better accuracy with some other guy's reloads with 250-255gr projectiles. Any thoughts or similar experiences? At 25 yards I am getting 3 out of six within 4" and the rest are usually all over the place. When I shoot the 250-250gr I am grouping them within 2" at 25 yards.

Much appreciated,
Patrick

Patrick.... you haven't even named the gun. All around paucity of info prevents any but wildest conjecture.

* Some round nose slugs are just that----slugs----with Center of Form (COF) to close to Center of Gravity (COG) for stability, a condition which seems to worsen as velocity is increased. A bullet of marginal balance is less tolerant of chamber-to-bore misalignment (OFFSET).

* Universal isn't as universal as its name implies; it can be a projectile and case sensitive powder. If you have a .45 ACP, try your bullet in it over a book charge of Universal.

* Your caper reminds me of an "experiment" we conducted in Junior Riflery half a century ago. We targeted .22 Short, .22 Long, and .22 Long Rifle. Short and Long Rifle shot with accuracy. The .22 Long came up short. The Long is made by seating a Short bullet in the Long Rifle case. None of our rifles liked the Long.

Sorry about that! I forgot some of the most important information. These are being fired out of my Ruger BH 45 Colt, 5.5" barrel.
