I have been working up some reloads for the one I have and its going to be a while till I have one I really like. I have been using IMR3130 and AA2520 so far.

I pretty much decided that IMR3130 is not the powder for the 7.62x54r.

I feel that AA2520 is going to be perfect for this round. It is slow enough that I haven't had any pressure signs at .5 grain from max load. Like any other round I have reloaded for accuracy is better below max load anyway. I will be loading more with this powder and will let everyone know what load works the best for me.

I still have some IMR4064 and IMR4895 to try.

I just got in 1000 Lapua D46 185gr bullets. So I can't wait to try these out.

I have a problem with the target sights on these guns, the aperture on the front sight makes a ring, then the front globe makes a ring, then the center of the globe is also a ring, so it looks like 3 rings. It is very , very hard to get a consistent sight picture.

Has anybody else had problems with the sights?

I am going to make new inserts for the front globe sight, maybe just a simple post and see if that helps.

Thanks,
Steve

I like these kind of sights. Just center each circle & you should be spot on. I only briefly saw one of the 28/76's that I had transfered so I don't recall......is the front insert able to be changed out? You could always put a post type in there and only have to worry about centering one circle

Yeah the the front globe allows for changing out the the inserts. No place to buy them them other than Gunbroker for around 45.00.

I did make up two post type inserts. It took a while but found using the insert as a stencil and using a piece the steel lid from Russian light ball and a file it worked ok. I used some tin snips to get it close then filed the rest. I then heated it red hot, dropped in water and cold blued them. Now I need to try them out and see if any improvement.
