Painless load development (mine)

[DadWil]

Yes. I’m not sure if 67 is completely compressed. I can still hear powder when shaking it.

That's not compressed
I got nothing then...
other than you're blowing more unburned powder out of the barrel with 67 grains than with 66 grains

At first I was like “at least I’m not old”, then I realized I kind of am. So this meme is literally about me

They're using 5-shot groups now instead of 3?? Progress!

Better yet, 10 shot groups, or two 5 shot groups on the same target to avoid over heating.

First 10 round group out of my 6.5 Tikka in its new Rokstok. I used this method with once fired Hornady brass. 140gr ELD’s loaded to factory length with 42.0gr h4350.

Looks like I have a good starting load once I rebuild the reloading bench.

42.0g is the highest I think I’d go and still probably be Walmart safe.

Yeah, I haven’t compared that load with my books yet. That may not be my starting point, but it’s around where I thought I would end up.

Here’s the brass for reference. I didn’t notice anything of concern but let me know if you guys see it differently.

I’m a 130tmk over 42.6gr of h4350. I’d say you’ve hit a great spot to load up and go hunting.

I don't see anything concerning, especially with Hornady brass. IME it's softer and shows signs earlier than tougher brass. What action are you shooting that load in?

41.5 H4350, 140 ELD or hybrid = peanut butter and jelly. No concerns of being hot in hornady, lapua, alpha, Norma, Sig brass. Peterson and ADG have smaller capacities.

Both loads are functionally the same for my purposes, however out of curiosity. In a 243 Winchester that I am working on, the 95 grain nosler balistic tip shoots 1.67 MOA at 100 yards for 10 shots. The 103 ELDX shoots 1.9 MOA for 10 shots.

At what range will the higher BC bullet begin to win out? Assuming it is a dead calm zero wind day.

I run both those bullets in my 243win, just a quick glance at my ballistic charts. MV for your loads is important to know.
Mine seems to be a wash to 500yds then the 103eldx seems to start pulling away past that.

Edit: JBM ballistics is free and has a huge library of bullets to play around with this very idea.
