Waner Flatline for 6.5X47 Lapua

[cg1shark]

Anyone have any load data where they have seen decent success with the Warner 121's in 6.5X47 Lapoopa?

I have RL15, H4350, Varget, IMR4166, 2000MR to work with.

My goto load for this gun has been 41.0 of H4350, CCI 450, 140 Berger Hybrid .010 off the lands. Low ES/SD numbers. Shoots exceptionally out to 1000 yards. Looking to find a load with the Warners as well.

I would use Varget. It's my go to for my 6.5x47L. Only needs 37.1g vs 41.5g H4350 for same velocity and extremely accurate

I have not been able to find the magic combination with the 140's and Varget yet in my rifle. My H4350 load consistently performs better that looks good in Varget.

Here's my 139 Lapua Varget 6.5x47L test. As you can see low single digit SD's and excellent accuracy for this OCW. Thats before even doing a seating depth test..

Here's my 140 ELD-M Varget OCW Test

Using a x47L 26" out of my AI, starting .030" off the lands

Varget low/ high load

35.5gr - 2900 fs
38gr - 2983 fps

settle with 37.9gr at 2970 fps Extreme Spread of 8


H4350 low/ high load

39.5gr - 2872 fs
41.5gr - 2984 fps

settle with 41.4gr at 2983 fps Extreme Spread of 9


In the end it didn't matter as I couldn't get those 2 charges to shoot when I did a seating depth test from .010", .020", .040" and .050" off the lands. It didn't group at all through the 100 bullets I use to get velocity and or fine tuning load in .1gr increments and seating depth part.

Any thoughts on why you were not able to get the Flatlines to group in the 6.5?

Idk. I shot a 7-Shot .33" with 140 Hybrids before I did my seating depth test so I know I'm somewhat capable of shooting alright groups. But the best 5-shot group was with H4350 at 1.18" lol. Wasn't able to get their 180's to shoot out of a buddies 300WM. Others have had similar results in not getting the Flatline solids to group well...

Yep I get it. Everyone says varget is the cats ass for 6.5X47. I just have not been able to find that magic combination with my rifle. H4350 continues to be the winner in my rifle. I did some Flatline testing today with RL15 and Varget velocity was really good however, the ES/SD numbers were not very good with either powder and accuracy was also really poor across the board. I am headed to Thunder Valley precision on Monday with my 338 hoping to get on steel at 1760, was hoping I would working something up with the Flatlines with the 6.5 as well, not looking promising unless I pull something out of my hat tomorrow.

Side note I was able to get the Flatlines dialed in with my 338 Lapua pretty quickly. Also have a load with the 180's in my 308 that shoots pretty good as well.
