For Speer 110gr SP, I use 20.0gr H110, CCI450, AVG 2346fps, LC12 brass, SD12, COL 1.9665" For Speer 125gr TNT, I use 18.7gr IMR4227, CCI450, AVG 2058fps, LC12 brass, SD11, COL 2.1625"
COL is from my dummy die setters - a few hundredths off the assembled length. I can't find any notes that state these loads shoots better, or worse, in any of my three rifles. My notes just say "Accurate" - sorry about that. Chronograph data is from the 18" BHW barrel and probably 40 +/- fps faster than the 5r 16" barrels.
Usual disclaimer applies - start low, work up slowly, check the reloading manuals, etc, etc.

Sounds like my notes! Then I started cutting out and saving the groups to look at when I'm tinkering.
Thanks for the info!

A miracle happened and SW had some 110gr Blkout's in stock for a decent price of 15 clams for 20... (much better than the 35 clams per 20 I've been seeing)
The box doesn't list it and I will call nosler later today, but assuming the test barrel is 16", the listed velocity on the box is 2150 fps. They are Varmageddons, so I am pretty confident that they used a longer barrel (20-22" maybe) for testing. So, I chronographed 5 of them and got a speedy 2340 fps. I didn't take my 9 inch barreled 300, but it has no space to mount the magnetospeed so it wouldn't have helped much other than group size comparison. Now that I have some of the same components as nosler, I'll load some up at their published data and see what the chrono says with the 125's and 110's.
Has anyone chronographed these out of their barrels? They didn't feed well- had to manually feed the last 4 to avoid the bolt marring up the brass and tips being bent up. Dont think I'd be buying anymore of them, since they grouped about the same as the 110gr hand loads.
3" group at 100 yards and 2" group at 100 yards w/magnetospeed- pics will be later.

It was the scopes diopter. It was screwed out so far (must have forgot to check it after I let another shooter use it) that it was uber sensitive to my cheek wield. Looked clear, good to go etc, the crosshairs would be "on", but really they would be off.
Screwed the diopter back in and I am back to getting bugholes with 125's.
Also said to heck with QL on this caliber. 17.5gr h110, 2.060, perfect on paper and no pressure signs.

16.6gr h110- 17.5gr h110 does the same. The bottom two are first and last rounds. Shooting pretty good. It'll make a good first AR for my daughter.
