I wasn't sure that is why I was asking the question. I have been seating the bullets to mag length with good luck on previous load work ups, not doing the ladder test method. If I start at mag length and than seat deeper, I'm not sure the bullets will like that because they already are jumping 0.14".
I think Sherm might have the best option of seating long and than getting an extended box. I wish Remington wouldn't put such long throats in their barrels.
I was planning on doing the ladder at 300 yards if I can ever get a good weather day. How fast does everyone shoot a ladder, do shoot one and let it cool or do all 10 at once?
Thanks

If you are shooting at 300 I am out. You are wasting your time. I am not going to waste mine. Good luck.
