9.3x62 (.366 Wagner) load advice?

Everything is tight, scope is good. I saw that the primers were flattened out so its too hot, my brass is also approx 3x fired or more at least . I did find some nice loads on hodgon site with imr 3031 and h4895 that I will also try out and get back with results.

Well I tried my first load for my 9.3x62 , approx 56 gr of imr 4064 and my grouping was approx 4-5inches at approx 100yards with a 4x power scope. Pretty disappointing to see this result. I know it was not my shot but rather the load. I think at the next gunshow I will just look for reloader 15 and hopefully get better results. I also have a possibility to use h4895 powder, is that a decent powder for this cal? If not i think I will wait until I buy reloader 15. It seems like all the shops around are sold out on the good powder.

try only necking only 1/2 to 2/3's of the neck down and seating the bullet about 10 thou off of the lands and see what happens .

Just quickly looking in the Nosler manual, your load of 56gr. of IMR 4064 with a 250gr. bullet appears to be well within their suggested min/max guidelines. What is your C.O.A.L. as that 'could' have a bearing, on preasure and excessive distance to the lands wouldn't help your accuracy. The reason I ask is prior to making up a dummy round, I measured the available length I had in the magazine as close as I could and got 3.421". I made the dummy round just slightly longer, chambered it and closed the bolt. Extracting the dummy and measuring, I got 3.398". In the Speer manual, I believe as in the Nosler manual, they list the maximum overall length at 3.290". For me in my rifle, 0.108" is way too much freebore. In other rifles, I find I 'usually' get my best accuracy when I can minimize the freebore to 0.005" - 0.010". What I settled on, in my rifle, is a C.O.A.L. of 3.323", partially because this would allow me to just slightly crimp in the lower groove of the 285gr Prvi bullets I'm using. Still 0.066", but better than 0.108". I would've set the bullet out further but I didn't want to cut short how much of the neck was actually gripping the bullet. I'll use that C.O.A.L. for my first kick at the cat and see how it works out. I may extend out further with my next batch and forget about that slight roll crimp.
 
Well I just tried another three loads. I did seat the bullets further out this time. Keep in mind this is not done on a bench but rather on a atv seat for a rest and also keep in mind I have a fixed 4 power scope. First load was with approx 54 gr of imr 3031 which got me a group of approx 2 inches. Second load was with h4895 56gr which got 1.6 inch, third load which was 56 gr of imr 4064 got me approx 3 inch group. On a normal bench I think all the loads with decrease approx 1 inch less . For now I will settle with h4895.

For any serious or semi-serious load testing, a more appropriate stable rest will definately be a help.
