GaCop, one thing has me stumped. Your listing OAL at 2.343", while SAAMI spec is a max of 2.800". I have the same bullets as well, the Nosler CC. Other bullets alone are about 1.5" long. While 2.800" is maximum, I just don't see how it's possible to have an OAL less than 2.400". Was this a typo?

No not a typo. That measurement is to the ogive, not tip. Sorry, I should have clarified that.

Got it. Yes, that makes sense now. Just threw me off as you listed it as OAL.

Heading back to the range this morning to test some 120 grain SMK loads. The Forster comp seating die came in so it will be interesting to see if the groups improve.

Not a nice day at the range yet again, 32 degrees with a 3 o'clock cross wind of 15 to 20 mph the whole time I was out there. Tested Both Nosler 120 grain Ballistic Tips and 120 grain SMK's. I only had 10 SMK's left and tested those with Win 760 - 44.2 and 44.4 grains. Seated to 2.255"(ogive), RP 7/08 annealed brass.

44.2 grains was nothing to brag about, 2.4" at 200 yards.

44.4 grains, 2951 fps, SD-5, ES-13, 1.270" at 200 yards.

Next up was the 120 grain Nosler BT's pushed by H-414, seated to ogive @ 2.270" Nosler brass, BR-2's.

44 grains, 2987 fps, SD-12, ES-27, 200 yard group of 1.889" with four into 1.167".

44.2 grains, 3003 fps, SD-11, ES-27 " " " " 2,192", four into 1,521".

44.4 grains, 3009 fps, SD-9, ES-27, " " " " 1.320".

44.6 grains, 3024 fps, SD-11, ES-41 " " " " 1.511".

Sadly, I'm now out of the Noslers too. I have some 130 grain TMK's coming in Wednesday and will resume testing later in the week.
