Hi Charlie.
I have been hanging around the forums for a few months, but this is my first post, so bare with me.
I have an MGM 14" 30-30 barrel for my Contender, and have tried a few different loads over 3 years. In September I went to sight in my barrel for hunting season and took a box of 160gr leverevolution, which I had used before with pretty good results, a box of new 140 monoflex leverevolution, and some reloads I wanted to try (I am new to reloading).. The reloads were in both 125gr and 150gr BT's, and the results were so-so. Guess my reloading skills need some work. I then did a 4 shot group with the 160gr Hornady's, and I got a 1- 1/4" group @ 100yrds.. I then tried the new 140gr monoflex and got a 3/4" 4 shot group @ 100yrds! Two shot were almost touching. I do not think I could do any reloads that would do any better. I hear the bullet performance on deer is also good, but I do not know from experience yet. Hopefully I can say something on that matter in a few weeks.
