What did you do in the reloading room today?

Worked up 20 of my Montana's favorite 257 Robts loads...100 TTSX sitting on 49.0 of Hunter, with CCI 200 fuses. Tweaking 3 different seating depths just to satisfy my curiosity.
Also annealed and prepped 100 addition cases of same.
I love all of the words in that post. 😎

What's the velocity on those TTSX loads?
 
Working on some 168 ABLR seating depth tests.
The first batch I just slammed in at 2.80 book length, but they weren't happy and grouped about 1.3
So I'm trying 2.82, 2.83, and 2.85 lengths next.
So the jump lengths will be
.067 (no go)
.047
.037
.017
I've heard a few comments that 0.05 worked, and 0.02 worked. But these have a reputation of being a little picky even in a match grade barrel.

I can stack most any 165/168 bullet on 44 to 45 grains of Varget and get a cloverleaf, but these are going to make me work for it. Hopefully one or two of the groups will tighten up and then I can do a little fine tweak.

In my experience, start real close, like almost jammed and work back in .010 increments. In my chambers which are not SAAMI, they don’t like to be much more than about .030 off.
 
What setup are you using?

Pretty basic stuff, RCBS RC-II press, RCBS auto prime, Lyman case prep station, hornady auto powder thrower. I try to size a ton of brass, clean off lube, and prep cases a few nights a week, then nights like last night I prime cases and drop powder. I’ve wanted to update my press but I’ve had such good results with all my cartridges this has been fine for me. I just plan ahead for matches and load accordingly so I don’t get behind.

Loaded the last of the 108 VLDs I had left over from my bench toy 6 Dasher for my hunting build- shoots them well enough (10 practice use. Have a couple hundred 105’s on the shelf though so I’ll shoot those up. Also pulled the spacer kit/original pad off my RS lite and replaced. Was ugly enough to bug me, and I’m fine without the spacers.
