This is the rifle the .405 Grenadier was developed for. I just got done doing some load work that I thought I would share. The primers are standard Federal Large Rifle. Brass was fire formed from Prvi Partizan 7.62.54R ammunition. Bullets were seated on the cannelure with the exception of the Woodleigh.

The load in red below had a cratered primer on the first firing so I stopped and emptied the remainder of shells with that load. It was the only pressure sign I have seen with any loads I've shot in this rifle. The load was just fine using the 300gr Hornady bullet so I thought I would try it with the 300gr Hawk -- bad idea.

Here is an interesting comparison:

And for those who haven't seen it, the rifle. It's nothing special but a lot of fun:

The sight picture I get with this setup is the same sight picture as the M16.
