Rl-15 vs varget

[Rogue3010]

I'm in the process of building a load for my 6 dasher and fairly new to reloading. It seems as if rl-15 and varget are the more popular powders for this caliber. I recently had a 6 dasher built with a bartlien 26in MTU 1-7.5 twist shooting 105gn hybrids. Like I stated I'm new to reloading and looking for as much knowledge as I can gain!

Rl 15.
32.9 gn.
2954 avg speed.
Sd- 3 Es- 7
*5shots

Rl 15
33.1 gn
2973 avg speed
Sd-4.8 Es-16
*14 shots

Thank you for the help anyone can give me!

How do the groups look?

I think RL15 and Varget seems to be the most versatile of any caliber. Could be it’s the least temp sensitive. I use both powders for the common military calibers, RL15>223, Varget>308.

 

[Rogue3010]

They are a little under a 1/2 @ 100 so not great by any means. I'm not sure if groups will tighten up once I get a few more rounds and stop my cleaning process for barrel break in. Or should I switch powders and try a heavier bullet with that 7.5 twist.

Have you tried 8208XBR? I’ve found this to be an excellent accurate sub for varget I’m starting to like it better

 

[Rogue3010]

No sir I haven't. I've seen a lot of guys using it. What are the advantages you are seeing vs the varget or rl-15? I had this rifle built to start trying to get into prs type shooting.

In my barrels 8208XBR and Varget simply shoot better than RL15...

However, my fellow shooters have great results with RL15...

 

[Rogue3010]

Looks like I'm buying some varget and 8208xbr to try! Have you guys seen a big difference in lot numbers on the way the powder performs? On the varget and 8208?

 

[supercorndogs]

Varget is pretty much famous for lot to lot variations. Although some recent experimentation I have read points to evidence that suggests it might be the amount of moister in the powder, and that drying it can help with the lot to lot variation.

8208 meter better than Varget and RL15. I use all three.

 

[Rogue3010]

I appreciate all the info! Also do you guys think the 105 berger hybrids I'm shooting are to light for the 1-7.5 twist?

8208 meters way better and my guns shoot more accurately with it but it’s not quite as temp stable but it isn’t terrible ether

105s are perfect in a 7.5 twist I shoot 95-107 out of my 7 twist creed and 7.5 twist 243

Varget 32.3-32.7 with 105 Hybrids have worked for me in two barrels.

 

[Rogue3010]

What kind of fps are you seeing, I just bought 8lbs of varget and found a decent load of 32.9 running the 105s at 2945

 

[Kjohnson 1972]

My barrel started really slow. I have 198 rounds on it now and I got 2953 w/ 32.5 varget. That was five shots through Lab radar at 93 deg.
