Well I shot the varmint grenades in 223 and they were very accurate but did not supply me with the graphic results that my sick mind requires! They just punch a hole through the squirrel and it crawls away and dies. I had been fortunate to live in the sierra foothills and the squirrels were plentiful on the dry range cattle ground where lead can still be used. But they have developed a new variety of almond that can sustain itself in this marginal ground with fertigation so invester's have ripped all this ground up for almond trees and eliminating my hunting grounds. Now I will have to plan a trip to southern Oregon in the spring and shoot sage rats and rock chucks with my remaining lead tips. On the non lead note I am currently in the process of developing a load in 25-06 . When I get the results I will post them for all to see.
If you're still working on non-lead loads for your 25-06, try this out.
50.5-51.0gr H-4831, Barnes 115gr TSX. This works rather well in mine. Hope this helps.
