We loaded some 100gr plinkers and some 110gr .30 carbine tracers and they worked fine. Groups on the tracers were nothing to write home about but the 100gr bullets were right around an inch at 100. I don't have the load data with me but I believe we were loading about 19gr of H110. We also tried a load with hodgdon 'lil gun and it was in the 18-19gr region. We were getting 2300+fps out of these. A chronograph problem prevented getting much useful data but the 100gr slugs were hell on waterjugs at 50yds.
We had a good load for the hornady 130gr flat point 30-30 bullets using 19gr of Hodgdon lil gun for one and I think we tried the H110 at around 20gr or so. Velocity was in the mid 2300 range and they were great for exploding water jugs at 100yds. That bullet runs a little slower in the 30-30 and is considered a more than adequate deer killer. I think it would make a great deer round in the 300.
The Sierra Load data shows it at 2100 but that is with a 10in barrel. I have a 16.5in barrel with a 1-8 twist so I can only guess it is around 2300. I originally bought the 110's to fire form my brass. I would post alot of pictures but the attachment limit is so low the pictures look terrible. this is the first I have joined a forum but I like the 300 round so here I am.
