Thanks man I appreciate it. If I remember correctly the SST fed and shot fine but the recoil damaged the Ballistic tip, which may or may not have affected anything at the range I typically shoot. And then the explosive exit I mentioned before. But like you said: 150s could be a whole different story.
If you find it difficult to get multiple bullet weights to perform with a particular powder, you may want to try a different powder.
Iirc the mag length on a 770 will let you seat at given data for most 150s without being close enough to bruise the tips, at less than 300 yds though, I wouldn't worry much about a bruised tip. 3.25-3.285" should be OK. The sst and btips are similar enough in the polymer it'd be hard to say lot to lot. Performance wise, the btips are SLIGHTLY tougher, minimum impact fps: 1800, whereas the sst:1600 (generally speaking) which, along with the reliable accuracy I find in them from cartridge to cartridge, leans more in their favor, under 200 yds? You'd not likely notice a difference between the two, they're both a hollowpoint for hunting, the increase in mass and reduction in speed from a 130 to 150 will show a much bigger difference than switching from a 130 sst to a 130 btip.
No difference noticed here with h4831sc, haven't seen non sc in years though....
Or something bonded, partitioned, or monolithic

Food and drink can throw off a good shoot/test. My dad always bought a dozen doughnuts before heading up the hill to a match. If we didn't wait till after the match, the scores tanked.You’re exactly right! In reference to the “me” factor, that’s where the Boyd’s stock will come in. I’ve found that I’m better ergonomically with the AR/vertical hand position. So I’m going with the AT-ONE stock. When prone, my neck was killing me from moving up. (Another me factor) so the adjustable cheek well will be great.
I’m also figuring out what I’ll do for rests while testing because I was getting some bounce even on the cheap rest I had. I think laying off the energy drinks with my prescribed Ritalin will go a long way too
Beautiful gun btw!
While I brought snacks and drinks in ice chest to USPSA matches, I ate beef jerky and drank water during stages and reserved caffeinated sodas and sugary snacks til after the match or stop by favored taco/burrito place afterwards. And having good night's rest and good breakfast with light stretching/body warm up exercise (You do a lot of running around for USPSA) also help as hunger pains before the stage can definitely throw off your focus/concentration along with upset stomach, tired body and poor sleep the previous night.
I have 3 young kids. You just described my all day, every day lolol
Yup. As kids we people can be real nerve frazzlers. I was five before I realized my first name wasn’t, “Dammit.”

Ladder up in smaller increments to start with, .5 works in .270 because of the huge charge weights, in .300 blackout, charge weights are more like 19 gr? So I'd ladder 19.0, 19.2, 19.4, 19.6, 19.8, etc, .2 gr increments, in .243 I ladder in .4 gr increments, in 7 stw, .7gr increments, in Grendel I would run .3 gr increments etc.
We really like the SC in the 270 short mag
After watching all 15 of Johnny's Reloading Bench channel videos in attempt to clone 77 gr OTM (Open Tip Match) Mark 262 by Black Hills to produce 2750 fps out of 20" barrel, I noticed using 0.3 gr ladder tests often produced inconclusive groups - https://www.black-hills.com/shop/mk-262-mod-1-c-mil-pack/556mm/

So far with this particular bullet I haven’t found a node yet, but the groups started coming together (if you want to call it that) as I went down. Problem is: per the book it’s slower than I’d like. BUT if it hits and hits accurately, who cares right? This gun won’t spin it like a top like the bullet may want, so slower may be better, if the gun/powder likes this bullet at all.
That I have not done. But you definitely have a point. The box stuff is so expensive but then again so is all this testing lol
