I have been shooting these rws musket caps for years. I bought a new leupold scope recently. I went to sight it in and every shot was blowing a small hole clean through the cap. I have never experienced this before.I am shooting a MK85 with 110 grains equivalent of triple seven. I use nosler 260gr bullets with MMP hp12 sabots. This has been my hunting load for 10 years now. Any idea why the caps are being blown out. Also, has anyone here had cataract surgery? I have always heard that you focus a scope by making the reticle super crisp. I can move any scope focusing ring and the reticles are always perfectly sharp. What I am aiming at is not super sharp anymore. Weirder yet is when I put the scope in 3 power the reticles and the background are sharp. If I put them higher then 7 the background gets a little blurry. Is this a byproduct of my surgery.
