A good friend was kind enough to let me borrow his custom Mountain Mold 700gr bullet mold. First off the mold is amazing to cast with once up to temp even with this HUGE bullet I have about zero rejects. After cutting the spur and opening the bullets fall right out, I have never used a Mountain Mold before and can see a few in my future. I sized them to .501" and pan lubed with a homemade random lube. To let you get the idea of how big this bullet is that is a 22lr on the left and a .452 300gr bullet on the right.

The load was 29gr of Lil' Gun, Winchester Large rifle primers, in Starline brass. No idea what the actual velocity was but according to Quick it should be just shy of 1500fps.

Ok on to the shooting. To say the recoil was harsh would be an understatement. I shot 10 rounds off hand and dont think I will be shooting anymore today. All the shooting was done off hand at 25 yards. I fired 2 3 round groups and shot steel plates with the remaining rounds.
First group

The 3rd round of the first group actually took the dot off the cardboard so I pasted it on different part of the cardboard box I had set up in front of the target butt.
