178 A-max at 600 Garand load?

[PhillipM]

I'm thinking of trying these out at a match this coming weekend. Has anyone got a good load?

In .30-'06 try 47.5gr of IMR4064 or 46.5gr of IMR or H4895 (+/- .5gr).

They both shoot to the same zero and have worked with every bullet I've tried from 110gr to 190gr.

My measure is locked down on 46.5 gn IMR 4895 based on your advise from long ago. It just seemed a bit much for a 178 grain in a Garand. We shall see.

Is there any advantage to seating past mag length with this bullet or any other in a properly bedded and set up Garand?

[Maury Krupp]

I haven't seen any gain from playing with seating depth in terms of jump and non-VLD bullets. Milspec 3.34in seems to work as well as anything there.

However, as a semi-experiment I started seating my long range loads with Sierra 190MK and Berger 185LRBT down to the ogive. That seems to make them work a little better. Maybe because of the better load density (esp with IMR4064) or maybe it's all my imagination.

I haven't done any blind testing; I'm not much on testing these days. The loads work as is and I don't have any WTF? shots so I leave it at that.

Thanks much.

One day I hope to shoot with you.
