Col?

[Bodacious]

I have some 125 grain nosler bullets with no cennelure, what should the COL be?

Also, the form says the brass hsould be trimmed to 1.355, what if I overtrim it to 1.28X or so? NOt a big deal, just curious.

PS: I decided to load one up to the same as a 75grain .224 bullet of 2.25 inches because if I had to seat it any lower it would be easy to do so and I would think that 2.25 would be the max being that the round wouldn't fit in an AR magazine if it got any longer.

I overshot it just a tad an got one in down to 2.2 inches and I notice that there wasn't much resitance pressing the bullet in there and the bullet isn't far in there either.

Any tips?

I haven't used the Nosler 125. I seat the 125 Speer between 2.050" to 2.100" COL making it fully seated in the neck or close to it.

I seat mine as:
125g Nos BT 2.130"
125g Sie SP 2.060"
