reloader22 for autoloader

[[email protected]]

I have been using hodgen H4831sc for my .270 win loads with 130gn bullets out of my bolt gun. and I recently started developing a load using reloader 22. I have been using reloader 22 in 7mm rem mag and wanted to try the same powder for both since I am out of the h4831sc. My problem is that I want to start hunting with my remington 7400 semi auto in 270 win, but I have read somewhere at some point in time that the slower powders would batter the actions of semi auto rifles due to there being too much gases or the wrong pressure curve. I have also been told that the 7400 action is prone to wearing out quickly. Mine was bought new in around 2003 and has not seen much action from the back of the gun safe. My goals for this load is to be a good 150yrd deer round for hunting wooded area. I considered moving up to 150gn bullets, but I have a stock pile of 130gn hornady 130gn sp.

I really don't have a good answer, and can only suggest trying some loads with the Rel-22. I would not push up to max loads, but maybe load a 5% under Alliant's recommended max. You should have a chronograph to see if you get decent velocity, or if you should try something a bit faster burning and a little more efficient.

Don't worry about the 7400 wearing out, as many problems can often be traced to poor owner maintenance. Cleaning and lightly oiling can help prevent premature wear.

I can't answer your question directly since I've never loaded for an autoloader, but I will state that H4831 and RL-22 are not that different in burning rate. Yes, RL-22 is slower but not significantly so. Just start 10% below max and work up slowly. If you are really worried about it, buy some more H4831 or try a faster powder.
