Thread: Refining loads through velocity plateaux

I commented in a recent thread to @ebf when he raised this method that we should give it a general airing on the forum.
So who has tried it and how did it work out for you?

A description can be found here.
Load Development (Part 1 of 2)

Yup, that is pretty much my current approach.

The article you link makes an interesting point about not doing round-robin. I'll have to give that a go and see, it does make sense. For shooting groups I prefer round robin, but pure chrony measurement I guess it makes sense to dispense with it...

If shooting the initial test for chrony results only, consider discarding the individual targets (just shoot everything at a single dot or even a spot on the backstop). It is very tempting to focus on group size and get side-tracked

The context is fairly important though. I am loading for maximum consistency in 10 shot groups, and also favour loads that are temperature insensitive, so would generally go for a mid range node and even go to the length of trying to find the middle of a node rather than sitting on the edge.

Would be interested to hear your current method, those groups you posted last week were VERY nice

I built a 6.5 Creedmoor for a client recently, he supplied the Krieger barrel & 308 Sako Forester, Scott chambered it & put one of his suppressors on it.
I loaded a total of 11, 130 siroccos with 2209 for the load development, never used them in a CM before
3 lots of 3 going up in .5 grains with two to get on the paper.

It has a 2-7 Kahles on it, shot off a bipod on a bench with a rear bag.



For a hunting with a 7 power scope that's not too bad.

No fouling, 11 rounds down the tube all done, GTG, just shows what a quality barrel & assembly can achieve
