Best Powder for 20" 6.5 Creedmoor

[Lefty7mmstw]

In the instance of a 20" barrel I would think varget would offer a more complete burn and possibly better results than the slower powders?

you really aren't that overbore with a 6.5 creed... I'd think the vel change from 22" to 20" would be a max of 50 fps or so on a given barrel with a given powder...

I'm testing RL-16, looks like I can get the Vel I need with a "calm" load. 41-42gr

I tried RL26 and cannot get enough in to see 2800 fps also halt the loads I tried were all compressed already and even with the ELDX searing stem it was leaving groves on the bullet

I then tried RL 16 and the velocities are not bad The top load got me to just over 2700 fps I think I can live with that

I'm trying to get 2605 - 2650, to match my BDC Turret

I have heard a lot about R-17 and H4350. However, I can't find any. Today I did find some IMR4350 so I bought that. I do have some Superperformance powder I bought a couple of years ago by mistake so I can try that also.

I just did a 300 yard ladder yesterday and what looks to be a good node at 2590 fps from a 22 inch barrel with a 7 inch suppressor.

I'm running the following;
New Lapua brass
143 ELD-X
Fed 210M
H4350
.010 off the lands

This was the top of my ladder and it showed no pressure signs at 41.2 grains. The node was 40.8, 41.0 and 41.2 producing a flat 1 inch group at 300 yards.

thanks slick8, i'll try the 41.2

I4350 will be just fine too... just run her up from middle 30's (36-37) up to 40-42 if you are using a 140'ish pill and she'll bark good...

RL-26,140 Berger's with Hornady brass at 3092 FPS out of a 26 inch barrel. I am doing load work on a 20 inch barrel now and will update with my results when I complete the test.
