That being said, I just loaded up on sps lubalox 3rds in 180 accubonds for my 300 win mags and an all around bullet.
What's "Grade C" anyway?
No idea.
some info here ....
180 gr Accubond "Grade C"Swamplord,
Would you have any issues with putting lubalox down the bore of any of your rifles?
I've loaded plenty of 180 gr 30 cal Failsafe & Ballistic Silvertip bullets for my Win 70 300 Win Mag back in the day, for moose, black bear, mt. goat & blacktail deer,
can't say I've noticed any negative effects on the rifle but back then I lived on the coast and spent a great deal of time circling the Kodiak Islands via boat & kept my guns very clean
