Great demonstration of easy load "development"

[huntnful]

This is a solid visual of just shooting what the gun likes, not making small tweaks to try and make drastic progress on an initially sub par load.

Picks a couple bullets to hunt with, tests them 5 shots each, with 3 different powders. Picks the best one as long as it suits his desired precision/velocity goals and go shooting/hunting.

And clearly the 135 is a very consistent bullet in that barrel, and an easy choice. Just nice to see it in unedited video form.

I skipped a bit to skim, but it seems I'm seeing more and more people point out that people get way too deep into the weeds of tweaking loads. And, the tighter the velocity numbers shot to shot, the more accurate a load is in a given gun. Almost like you could predict how accurate a load would be with just a chrono?

That’s a bit of a stretch with the velocity ES totally correlating to an accurate load. I’ve seen tight ES’s shoot like shit.

The last load he shot had a great group still and the worst ES of the whole batch.

I personally just look at group size, and if the ES/SD isn’t through the roof where it can actually cause a lot of vertical dispersion at long range, I just call it good.

I had a 1/4 MOA 5 shot group at 600 yards that I shot with my 22CM that I believe had an ES of 50FPS

Really good to know. It would be easier to count the pistol rounds I've reloaded by weight or volume, than round-count, but I've got extremely limited rifle reloading experience. Mostly just a little .223 and 30-06 around Covid, to have some ammo to shoot. But I got way, way too deep into the OCD weeds with that, and backed off, given limited time. Anything I can do to get good results without triggering that OCD deep-dive is welcome info.

Yea seems like low ES doesn’t always correlate to the best group

 

[wind gypsy]

I dont even hardly pay attention to SD/ES anymore unless it's atrocious. Start getting to about 20 SD I'd not be fully satisfied but its fine for any distance I can ethically shoot at animals. Match guns I'll want a bit better. Good news is near anything ive ever loaded in 6.5x47 shoots single digit SDs.

Those 135 CH bergers do seem to be a very forgiving bullet.

This is 100% true in several loads I’ve developed.

This load had an ES of 75fps and it still shot groups like this consistently.

 

[mtnbound]

I'm right there with you guys, not worrying about the ES/SD, I want the best group at an acceptable velocity.

I think ES/SD is mainly a result in case/chamber design and component/ reloading consistently. I didn’t think inherent accuracy/consistency was a thing until I started shooting a dasher.

Why else would it be that my dasher can have a single digit SD pretty much all the time, even with 10+ rounds but I can’t seem to get a creedmoor or a 223 even close to that for 10+ round groups.

I’m starting to wonder if there’s more to case design. I kind of want to test out some 223 ai to see if sharp shoulder angles and straighter case tapers are what does it.

I shot factory Berger ammo in a factory 6.5cm tikka barreled action this last year for an nrl match. Unreal groups, but 90fps ES if I remember. Longer shots left me with some head scratching, sub 600 was not an issue.

300 NMI is the same way. One of the best, most consistent shooting cartridges I’ve messed with.

Does this change at all when necked down to 7mm?

Absolutely. It just more volatile, if that makes sense. Still shoots plenty good to kill animals out to unnecessary ranges, but not the consistency or accuracy as if you leave it 30cal.

I guess another example is 300wsm being so popular in long range paper stuff.

I need to experiment more, it can’t just be magic. Some cases just seem to be more consistent.

Man, that's so interesting that such a small difference in just that one dimension can start changing consistencies like this. OCD tripwire is humming now...gah.

Yeah exactly. And I agree for sure.

I think there’s just some instability about burning massive charges down smaller bores. And also think shooting bullets extremely fast amplifies their inconsistencies.

But I have had plenty of hot rods that shoot super good given the performance they’re putting out.

Back when 28 nosler /N570 was all the rage I watched many shooters move erode their throat trying to tune a group so far that their “node” fell apart and they had to start again. Which moved their throat and again they would seek to tune
That combo was a self licking ice cream cone for components and OCD reloaders

Demonic trap.

GUILTY AS CHARGED hahahaha. So true though.

300 Super WSM isn't super well-known yet, but has real potential there.

That thing don’t look right…
