An old plastic garbage can was in the garage and the lawn needed mowing. I packed the garbage can with fresh cut wet grass and compacted it as hard as possible and hauled it out to the hills to shoot full of holes. Another 10 gallons of water filled the can just to make sure the grass was well wet and again compacted.
I chose 750 yards to conduct the shooting with a 308. I shot 210 LRAB’s and 168 A-Max. Estimated impact velocity was 1657 ft/s for the 210s and 1161 ft/s for the 168s. Energy indicated 1280 ft lbs and 1161 ft lbs respectfully. Pictured are bullet fragments recovered from the garbage can and from the dirt behind. All LRABs exited the can and impacted in the dirt where the bullets were recovered. Only a small number of A-Max bullet fragments exited the can.
Pictured above are LRAB bullets weighing 100, 140, 149, 157 and 171 gr.
Pictured below are recovered jackets from the A-Max bullets. These were the biggest pieces of A-Max fragments found. All A-Max jackets had separated from the lead. The largest pieces of jackets weighed 20, 26 and 38 gr.
There were other smaller chunks of lead and copper found but of no substantial size or weight.
Take what you want from this. I found the LRABs to expand quite well for that range and impact velocity. I also saw no reason to shoot them at farther ranges. An impact velocity of 1600 ft/s with energy of 1200 ft lbs is as low as I would consider for harvesting a big game animal. Others may have different opinions but with my 300 RUM shooting the 210 LRAB this takes me out past 1500 yards……A range beyond my comfort level with this gun even under ideal conditions.
