What could be causing this? It is my buddies dads rifle and has less than 100 rounds through it. I know there is

I had the same problem with my Mini 14. It would dent them so bad I couldn't reload them. That was if I could find them, it would also kick them about 30 feet. Just two of the reasons I don't own a Mini 14 anymore. Key
 
Go to perfectunion.com and bring this up. A lot of it has to do with the gas bushing that operates the op-rod. You may want to switch to a smaller one. kwg
 
Ruger uses a bushing size that is larger then the hole in the barrel. I believe the hole in the barrel is .062". I have switched to a .050 and it has worked pretty good. With my load that I use the most, I was able to use a .040 in the summertime. But once it got cold I had to increase it to .050. The reason Ruger uses a large hole size is to make it more reliable with most all loads. If you tailor it to your load, you can drop the brass at about 3 ft instead of 20 to 30 ft. Your load that you shoot will make a difference. The easiest way is to get an adjustable gas block and it can be changed with the turn of a screw. Again perfectunion.com has alot of information on this and many more simple mods that can be done.
 
I think Rugershooter is right on the money with using a smaller bushing. I think if your friend's dad were to switch to a smaller bushing or go the adjustable gas block route, it would at least dent them to a lesser degree if not stop it completely. One thing I did find though is that my mini would eject factory loads 20 feet dent the [beeep] out of them, but my reloads stay nice and close and dent free...a nice surprise. I hope the newer ones are more accurate than mine though; it's no shooter.

I would definately do some reading on perfectunion.com. They have a lot of good suggestions on there. I would start out with heavy slugs. My older mini liked 60 gr. Vmax. I installed a flash supressor and it cut the groups in half. I guess the weight of the supressor helped dampen the barrel harmonics. Install buffers front and back to help a scope last longer. Use a smaller bushing to reduce the force that the bolt opens. I have installed a solid bushing to prevent the action from working when testing loads. I got some good groups by limiting all the movement of the action. Also torque the gas block screws to 35 inch lbs. (not ft. lbs.) and make sure the space between the gas block halves is equal on both sides. I was able to get my older mini to shoot 1 1/4" groups at 100 yds. So far, with my target mini, under 1 inch is no problem. My best group was just under .4 in. with 40gr. balistic tips.
 
If you use a gas bushing with an opening of .042 to .045 it should function 100% without flinging the brass into the next zip code. Might as well get the bushing and do the swap and gas block torque all in one shot.
In my rifle, the bushing is .188 diameter, so you could make your own out of 3/16" drill rod if you had a lathe handy.

You need to measure yours, though, since they made some changes to the bushing recently.
 
I used a .045 with 40gr. BT and 26 gr of Win 748 and it cycled fine in the summer but wouldn't when it got down to 20 degrees. The 60 gr. V-max worked fine. There must have been just enough pressure difference.

That's an awfully mild load.
I'm using 26.5 gr. of W748 with a 55 gr. bullet and it's not showing any pressure signs.
Where did you find the data for that load?
I'm just sayin.

I check my load data when I got home. It is 28 gr. of W748 with a 40 gr BT. I should be more careful posting loading data when I am away from my books.
