I have a 1895 marlin. I have put some hot loads thru it. But can't find any loads that shoot under 1.5MOA that are hot. For example, I have been working with IMR4198 and 300gr partitions. I get 1.5MOA easy with 42-46gr. But after that I get vertical stringing and gets worse the closer I get to 52gr. I am kicking out at around 2000fps. Not exactly a hot load. But it does the job. I might start working with 3031.
