Yep, it'll work. You will also find out a better bullet for that rifle is the RCBS 405 gr. The nose is the right length to crimp in the groove and feed through the magazine, and they cast out at .460, which seems to work well in most Marlin barrels. They also make a 300gr. version with the same nose shape, so if you want a lighter bullet it's a good choice as well.
