Thread: 7x57mm 1st effort - comments?

Well how interesting...picked up some mag primers today, Winchester and Federal as that was all that was in stock at 2 places. Planning to ladder test the winnies side by side same charge with Fed 210 standard LRPs with R 19 using data for 130gn pills from Lee Modern Reloading 2nd Ed. Also been reading the thread re Cortina method of bullet seating etc so decided to see if I could measure chamber depth using a empty case with a bullet started then chambered and bolt closed. Works great, except it turns out I don't have a bullet long enough to reach the lands. With the various ones I have, the longest I can seat a bullet out and still be in the case is 3.281in. So guess I would have no trouble going to 220 gn subs if I can find any lol. Will do the next test with a 3.000 seating depth. See what happens.
