A semi-local fun shop had this in the rack, and seeing that the 38-55 is one of my favorite cartridges it seemed appropriate to do the paperwork.
As background, I have two Marlin 336CB rifles in that chambering; one wears the factory-length octagonal barrel, and the other had its barrel cut to 16.5" by a former owner. Both of these Marlins have groove diameters in the .379-.3795 range, and shoot the best with .380 GC bullets, which I purchase from Moyers in central PA. The Marlins suffer from the same undersize chamber malady as many have reported with 38-55 Handi. My solution was to purchase the short 38-55 cases from Starline which have thinner walls than Winchester brass, and the Moyer .380 GC in the Starline brass chambers beautifully without any interference or extra force to chamber. I get superb case life since I "mouth size" only.
Back to the Target Classic: Once home I slugged the bore about 2" in from each end and measured the groove diameter - .3795" for both slugs. So I took some of my Moyer/Starline loads using 11 gr of Unique and ran the Target Classic. At 100 yds off the bench with the Williams Guide rear and Lyman 17 globe front, I was rewarded with a three-shot near-cloverleaf group about 1" in diameter. Twice. Thus satisfied that I have something with potential that I can work with, I returned home and cleaned it and hung it up for better weather.
I may have overpaid at $400 OTD, but as most here know these Target Classics are out of production and their foibles are fairly well known and understood. Mine appears to have fewer foibles than some, but I can wait for Spring to confirm it.
Photos follow; L & R views of the Target Classic, one with its sibling Buffalo Classic 45-70, and a photo of the two Marlin 336CBs in 38-55.
