Well I just stopped at gander mtn. They don't have any marlin 338 s or ammo the guy there said the ammo is very hard to get.
And looking at the ammo I found 4 boxes of 450 marlin.
He told me they ordered the 35 rem ammo. So now I don't know what to look for in another lever.
308 Came Out In 2007 The 338 Came Out At The End Of 2008 As A 2009 Model. Anything With A Serial # Starting With 93 Or 92 Should Be Ok. If It Starts With 91 it Needs To Be Checked For Barrel Droop. Ammo Availability Is Spotty, Take It Where You Find it.
I have never found the 338 Marlin ammo on the shelves here in NE Florida. I reload, but I ordered quite a bit online. In the past I have found it at Midway, Midsouth, Grafs, and Cheaper Than Dirt. I found a couple of boxes in a Bass Pro Shop in Georgia, and a couple in an Academy in San Antonio, Tx. I have found that its generally cheaper to order 10 boxes online and have it on hand than have to hunt for it during hunting season, especially these days. These days reloading is about the only way to ensure you have the ammo you need.
Good information TR, having not been in the market for a Remington I was unaware that MR was even in the equation.
I ordered 5 boxes from Cheaper Than Dirt a few months ago. I like a decent supply of the same lot number. In all candor I've never had a problem finding 338 MX ammo on line.
