The bullet I have to try are Hornady 75gr ELD Match. I have almost 200 that were given to me so if they don't work well or flop I'm not out anything but some primers and powder. This heavy a bullet is all brand new to me so I have no idea as to what I should expect to find. Now I have already done a soft jam in my Savage Model 10 and they will fit and feed. The soft jam measurement is 2.420" and the Hornady #10 has a seating depth of 2.390". So I will seat them to that measurement. Question is which powder has the best chance of producing good results from these four that I have on hand; TAC, 2460, BL-2(C) and Varget... So far I have not used any 2460 or the BL-2C so I don't even know how it measures. I have used the other 2 powders with a Hornady 68gr Match and they both did well with the TAC a bit better. Also not certain but I believe the Varget could get to a compressed state if high enough.
