A good bullet is the Speer Mag-tip. It is designed to expand at low velocities but has a heavy shank to control or stop expansion. I do not know if it will feed good in an autoloader. The Mag-Tip is protected to prevent damage. To me they look similar to the Remington pointed C-L.
Remington says the bronze point is designed for rapid expansion at a controlled rate. I have taken a number of deer with it and never had a bronze pt. exit a deer. That is with the .270 Winchester. Dad and a brother had success using the 150 grain bronze point in factory ammunition. At one time it was available in .300 Savage. They had success with the bullet, most of their kills were from 25 yards out to 150 yards. I do not recall finding an intact mushroom bullet in their deer.
The bronze point is the most explosive bullet I have used on deer. I have loaded and fired close to 400 of them in the .270 Winchester. Many of them were used on rock chucks and jack rabbits. I was amazed the first time I shot a rock chuck with one. I lost sight of the rock chuck in my scope. My partner told me to look at the big RED spot of the lava rocks. The bronze point had turned the rock chuck into a red spray on the rocks.
Express Bronze Point Tipped Bullet
A superb choice for long-range medium game. The high ballistic coefficient of the bronze insert produces a flat trajectory and maintains high velocity and energy at extreme ranges. Yet on impact, the tip is driven backward to create rapid expansion that is controlled to optimum limits by the pre-grooved jacket, even on thin-skinned game. The tip also protects the bullet nose from being deformed by recoil while in the magazine.*
To give you and idea regarding .300 Sav. velocity I fired a number of old .300 Sav. rounds across my Chrony. These were old Remington C-L, 150 grain bullets. The average velocity was 2458 fps. My point is that the 150 grain bronze point likely produced the same velocity. It worked on deer. This was out of a 24 inch barrel. I am sure that little brothers' M99 Savage with a 20-inch barrel produced much slow velocity. The bucks never new the difference. Most likely "true" .308 and .300 Sav velocities are withing a couple of hundred feet of each other. A short barrel .308 might produce the same velocity as a long barrel .300 Sav. In a recent phone conversation little brother(big) said he was boxing up a bunch of .300 Savage rounds, brass, and .308 bullets for me. If there are factory bronze pts., and other factory bullets I have not fired across the Chrony I will take advantage of the oppertunity.
