[QUOTE="Cowboyshooter, post: 1516381, member: 83113"] It is easy to fall into the trap of "heavy" is going to penetrate. Seriously too many bullets do not work very well except in a somewhat narrow range of velocities. :( When using a 150 grain it is only going to start at around 1900 fps out of an 18 inch barrel. Why that length is commonly used I have no idea. Out of an 11 barrel you are possibly going to be at 1500 fps or less. Either way you will be most likely be less than 1,000 foot pounds of energy. If you use an expanding bullet, the chance of getting all the way through is almost zero. What I have found in mine is that the really heavy bullets. 208 to 240 grain, do not want to stop. They do not really expand, some barely show any sign of being fired beyond the rifling marks, these are all sub-sonic rounds out of a 16 barrel. Very little energy but lots of momentum! The real problem you are having is the length of barrel, 11 inches is not much for what you asking of it. :( The other side of this issue is using something which will leave faster and is lighter to allow this, but it will come with a trade off, muzzle blast! Lots of it!! An issue too often exaggerated is the absolute accuracy. If one rounds prints a two inch group at 100 yards and the other prints 1 inch at 100 yards, often people jump on the smaller group as the better round. Sadly it may not be the best round for the job. When I started pistol hunting for deer, I was using a .44 magnum in a Super Blackhawk. The factory ammo did a really poor job of penetration so I went well outside of the norm and used 265 grain bullets designed for the .444 Marlin round.

By doing some work with wet newspaper, not sure where to find those any more, you can really learn what is likely going to work and what will likely let you down. I would not give up on the .300, I certainly like mine, but some shooting into a cheap, wet media will really help you understand what works and what is going to disappoint you!
