6.5 CM Starline case capacity is very close to Lapua, but less than Hornady by enough to change the load a bit.
of all the powders listed there, h4350 is slowest at max powder.
A month earlier I got 2777 fps with sd 9.1. Used Magnetospeed V3.
Was basically making brass for another gun.
Probably the biggest weakness in the RAP as a value package is that plastic mag.
I'm thinking their marketing was aware of this mag weakness and thought up a clever two-fer…
(1) Solve a reliability issue with a (2) desirable magazine upgrade feature, ie, sell more guns !!
COL 2.88" SuperFormance from 44.3 up to 47.0, but only had decent results around the low end of that range.
Pressure signs at the upper end, so start low like I did if you try SuperF.
Gave up on the pill since 140s are much easier to work with in the SAV 10.
I initially had my eye on a 223 RAP, but the supply was weak/demand high, then I lost interest.
Here's a link : RAP 6.5CM with AI mags
I'll say it again, the 6.5 Creedmoor was designed around H-4350 and a 140 gr …..Agree, and that's a great way to start.
I've had a tad better results with H100V on the 140s.
Best results with Varget was for 100 to 130s then 8208 for pills less than 100 gn.
All of this with 22" RAP, 24" SAV 10, and 24" AR10.
B&C fit was perfect and agree with all that goathead said..
see link : RAP s B&C
UPDATE: did a little Dremel work on the mag retention lip and front rounded corners to get the mags to pop out without sticking.
Zero didn't change and did this 200 yard 3 shot group last Wed.

...or walk out to the range without them.Guilty ..
My goto pill for range 6.5 cm small groups.
This is a simple visual with no scientific method, and the 140.0 bin has been already been emptied once, so it really should be +200 pills, ie a lot more/higher than 139.9.
I pick a bin to load a series from, to keep the pills within a small weight range.
