I'm looking to find a good 338 solid bullet for the 338 lapua. Anyone have any experience using brass solids in there 338 lapua? I'm looking for good penetration power at long distances. Yesterday I was shooting a cinder block at 1000 yards and the Bergers 300gr OTM only put about a 1/4" dent in the cinder block, I want to demolish it at 1000 yards with the 338 lapua. At 500 yards the Berger OTM's do the job but not at 1000 yards on a cinder block. Thanks in advance
