Back at Christmas of last year I got a new to me 1933 Tula HEX receiver 91/30.  The stock was in fairly bad shape finish wise but the bore was good and bluing just needed some minor touchup and the bolt needed a good polishing.  While I was at it I cork bedded the action and refinished the stock to a blonde finish instead of the traditional red shellac finish.

Great doings Res45. While working up loads with your 7.62X54R, you might want to go back and read the article “Finding a Cast Bullet for a Russian 7.62X54R Mosin-Nagant” by John Rhodes in The Fouling Shot, Sep-Oct 2014, issue #231.

I liked the article and like both you and the author, used that Lee 185 gr round nose bullet. Much like the author, I also had good results with IMR 3031.

I get good results with that bullet in an o3A3.  That bullet can be nicely hollow pointed for hunting with the Forster HPing tool . I use the tool in a drill press on loaded ammo and it works great for such an inexpensive tool, it self centers well. I cast them in Lyman #2 and use aluminum gas checks and tumble lube. Mine group just under 1"@50 yards@2150 fps using H4895

Gary I have plans to purchase one of those HP tools as I have several mould that would benefit greatly in a HP. 

On the H4895 I know Hodgdon has the 60% starting load with this powder.  With this particular bullet what would be a good starting load an from that point what increments would you work up in.  

I don't think with this particular barrel twist anything much over 2K fps. is going to hold accuracy which is more important that velocity but I would like to get it up close to around 2000 fps.

From my personal extrapolation approximately 33.4 gr H4895 should produce just over 2,000 fps with the 185 gr bullet in your 7.62X54R rifle. Chronograph that load and then very accurate projections for lower velocities can be found with charge reduction software here:

45.4 gr H4895 is a capacity load  Maximum in your application. The minimum recommendation is then 50% H4895 or22.7 gr, so the 33.4 gr for ~2,000 fps is well within recommended safe load range.

The Hodgdon data for a 180 gr bullet in your caliber is safe for your bullet, and my extrapolation is based on that, Hodgdon Data:

Check out this thread. It's my quick evaluation of the C312-185 in my own Finn M39 7.62x54R with 4895.
