[QUOTE="Raffy, post: 2492449, member: 118545"] You could just seat them at the max allowable mag length and see if they shoot. The hybrid ogive design seems to be pretty forgiving on seating depth. You will probably have to tune it a bit by doing a seating depth test. Try doing a pressure ladder with them seated to max mag length. Once you have your max powder charge you can back it off 1 to 2 grains and seat your bullet a little deeper at a time in groups of 3-5 rounds at each incrementally smaller seating depth. Ive seen lots of different variable increments and most of them probably would work. You will see your groups continue to shrink as you approach your optimal seating depth and then when you pass it you will see them start to open up again. If you dont see that, then your depth increments may be too course and you probably jumped over it. Pick your favorite group and that will be your new seating depth! You will see your impacts on the target wander around a bit. I would look for a string of good groups that print to the same poi on the target relative to where you were aiming for 3 or so depths in a row and use the one in the middle of that as long as the group size is acceptable to you. There is a really good video on youtube by Eric Cortina about chasing the lands. He can explain it much better if the above doesn't make any sense. I dont know what to say about the cracked necks. Keep us updated with what they say about that! [/QUOTE]
