That is what I used also during Muzzle. Aimed for the high shoulder and got complete pass thrus and instant drops. I did find the rep tip, which was cool. Found copper and lead dust in and around the meat of the entry/exit holes. I've reloaded my daughters .243 with SST's. and pulled them out of the logs I was using as a backstop and they also mushroomed beautifully. SST for life.
