Re: I need to change my 300 rem mag
You can also find someone who has the skills to reload and have them work you up some lighter loads. You will need to tell them what you plan to do target shoot, hunt, etc. I work up loads for my 300 that are light enough for my girls to hunt with. They weigh in about 100 lbs not very strong to boot but take deer at ranges to 200 yards with no problem and light recoil. I use 150 gain barnes bullets for this round which does a very nice job on deer. I also shoot a 308 which has a 22" barrel and very light recoil shoots well to 500 yards with factory loads not a hard kicker and weighs next to nothing you may want to consider going this way. If you go with a muzzle break please be sure you use very good ear protection the report will be very load.
Good luck and happy shooting
