Rick,
The article is from Handloader May/June 1985.
The list of 303 Bullets from factory loads was apparently compiled in 1948. The factory loads had to be pre-1949. The article makes reference to Philip Sharp's "Complete Guide To Handloading" for this data.
On a side note, I have not slugged the barrels of my 303 Savages, but they both shoot .308 bullets just fine. About 2"-3" groups at 100 yards with a peep sight.
I believe the 303 Savages were made with .308 barrels but oversized bullets were loaded to increase pressures and velocities.
I suspect guns with a lot of these oversized bullets thru them are now showing signs of larger dia barrels.
I am working on getting this article scanned at a decent size for distribution. My bullet puller will be here tomorrow and I will be gathering data for factory loads of the following bullets:
Remington 180Gr - (two different boxes of different years)
Dominion / CIL / Imperial - 190 Gr. (three differnet boxes of different years)
Winchester / Western - 190 Gr. (two different boxes of different years)
