9mm load question

Recommended Posts

I've been loading a Summers 145 Hi-Tek with 3.1gr of Titegroup. This clocked 930fps out of a G34 and was a great shooting round. 

I'm gonna try the same bullet with N320 and it looks like 3.1~3.3gr is a common load. 

Does this look like a good load to start with?

Thanks!

Yeah 3.2 grains would be a good place start.

Agreed.  My experience is +0.1-2g for minor loads and +0.2-3g for major loads is about right for TG-to-N320 to start.

That is a sound starting point.  Depending on barrel length and gun related factors, you may need to bump it up a little, but chrono first.

Sounds about right, based on Vihtavuori data. Chrono it and see if you need a little more, or not.
