Primers & Powder

Unfortunately no. This is what works in that particular person's rifle with that lot of powder. There are so many variables in reloading that your best bet is to try a load in your rifle, then swap something out, and try that. When swapping out components, you need to back off to starting loads and work your way up again looking for sings of pressure and also see if the load is accurate in your gun.
I've got to order some primers this morning to go along with my 4895 powder,for loading both cast and speer 270gr bullets for my 9.3x57.Is there any DISADVANTAGE to using the #215 vs the #210 primer?[the discussion here was the #215 seemed to result in a more more consistant velocity with 4895 powder]

My rule of thumb has been to switch to a magnum primer when the powder charge exceeds 50 grs. or during normal winter temperatures. Since I've lived here I have used magnum primers for almost everything with no difficulties experienced, and it has included 4895 in the .243 and the .30-06.
so-from what I can gather from reading this thread on 9.3x57 loads, my powder charges would be UNDER 50gr of 4895,so would that mean you would choose the #210?I do plan to use this rifle for hunting, and that would likely be under cold or wet conditions[What advantage/disadvantages are there to using one over the other?

If your powder charges are below 50 grs, and you are not going to use the rifle when the temperature drops below zero degrees fahrenheit, the standard primers will be fine. If the ammo is going to be used in extreme cold, it wouldn't hurt to use a magnum primer.
The use of a magnum primer might result in a little loss of accuracy, or it might not - there are many variables. The magnum primer is stronger, so the ignition of the powder column will be more violent and there could be an increase in pressure. If the increased pressure created by the magnum primers has a detrimental effects your rifle's accuracy, you must determine if the trade off between the loss of accuracy and the benefit of more consistent ignition is worth while. I think that for the cost of a 100 primers it is a worth while experiment.
