I recently traded into a Marlin 335, JES Rebore to 38/55. Nice looking and great looking bore. I miked it with a set of calipers, and get a bore size of .355, groove to groove and .366 land to land, does that sound about right? The guy had gotten some reloads from another friend of mine, who used the longer version of the brass, and it closes hard the last little bit, I worked a loaded round, in and out with some effort, and saw abrasion on the brass behind the bullet, obviously this is chambered for the shorter length brass. I only got around 20 rounds of brass, that was loaded. What is the best bullet weight to shoot, 245 to 255grs? The rifle has Williams peep sights, and shot great, 3 shot group at 100 was around 2.3 inches. It had more zing than what I expected. I will get the load data tomorrow from my buddy. And what is JES's web address, ph#.All replies appreciated.
