Did the 38-55 used to have a really slow twist? 1:20" was the norm back in the day for factory barrels. But the famous makers used very tight twist rates! My Schoyen in .38-55 is a 7 groove 1:15" twist rate.

	The Cartridges of The World indicates the modern .38-55 uses a 18:1 twist. Traditionally this caliber used a 255 grain bullet. Many shooters have indicated their older .38-55s had a 20:1 twist. Therefore the 255 grain flat nose bullet in a 20:1 twist barrel had a Sg of 2.35 and in a 22:1 twist barrel had a Sg of 1.94. Shooters have been putting on barrels of tighter twists (1:16 or 1:15) to use the heavier (360-370 grain) bullets.

	Sounds like they were over twisting all their bullets is the good 'ol days

	I have more people indicating they have trouble getting their .38-55 to shoot well. I believe it is a case of not matching the right length of bullet for the best gyroscopic spin for the specific rifling twist in your barrel. There is a variation of twists being used in .38-55 barrels and not everyone has today's standard twist of 18:1 which is tighter than the older 20:1 or 22:1 barrels. And yes even the old timers were trying tighter 16:1 or 15:1 twists to shoot longer heavier bullets. No they were not overspinning their bullets in the old rifles. Generally they were using bullet lengths and rifle twists producing a Sg of 2.0 or slightly less. Overspinning of the bullet is when you go over 2.0. However a bit of overspin say between 2.0 and 2.4 may not show any effect (unless it is also a hot day which will increase the Sg). I prefer to select a bullet that shoots a Sg of 1.8 to 1.9 on a normal cool day and which will still shoot as well with changing environmental conditions.

He lived outside Rogue River, in a community called Wimer, about 15 miles from me and we shot at the Josephine County Sportsman Park We shot slug guns together and he was a excellent barrel maker. He used P&W machines to make his barrels. No better man, ever walked this earth. These are match results. His first name was John but, everyone called him "Danny". 1992 was about the last year that he shot. His health was failing at that time. I'd be interested in that barrel, if you ever decide to sell it Frank

	I've had a number of people tell me that they have had no success in getting .38-55's to shoot well. Mine were pretty easy to get shooting. I think that a lot of the problem has to do with people using reamers that don't match their bore/groove ( i.e. original spec bore groove vs modern spec barrels ) and the differences in case lengths as well as big thickness differences between Starline and WW brass. If you pay attention to all of the dimensions it's pretty easy to make them work IMO. Chris.

	Frank, thanks for the info, probably means barrel was inserted in the early '90's? Will keep you in mind. Thanks, Ed
