VV Powder Recommendations

[Justice1327]

Thank you for the information I'm hoping to stay away from the hard the flow powders. I'm not sure how my V4 would handle the long kernels.

I have a v4 it has no problem with n565/n570

Gave N560 a try in my 6.5-06 recently and it did well with 140 SGK's. They are large kernels for sure but metered reasonably well in my chargemaster.

I use n165 with eldm 123's and 130's. I can stack 20 shot groups in an inch in my 6.5prc. No fliers. And it's temp stable. Kernal size reminds me of 4831sc.

Oh and you can actually buy it.

N165 and N560 work well in the 6 .5 PRC , N165 burns cool because it is single based N560 will get you max vel , but is double based . N560 and rl26 loads about neck and neck in the 6.5 PRC . I have great results with both powders.

I just learnt a thing! Thanks.

I've used 140, 530, 540, 550, 555, 560 and 568 in various cartridges.

140 was ok but too slow for my liking this was 6.5x47, 223, and 308. A long time ago.

530 in the 223 was awesome but my barrel was toast in 3k rounds. But I was shooting a 80gr over 2900 from a 22".

540 for me uses almost the exact same changes and behavior as varget. I will be going to it in my 6ARC. I haven't used enough to see how it compares on barrel life, but it has been easier to get.

550 I tried in the 6.5x47 and it wasn't great. I should go back and try it in something more suitable.

555 will be my go to in my 6.5 Addiction (6.5x55 semi-ai) very consistent and seems to burn between 4350 and 4831. I've also tried it in 6.5 Creedmoor and it has been very accurate and consistent. I have a supply of RL 16 that gives better velocity, but will probably use vv555 for that as well as RL 16 is hard to get.

560 was my absolute favorite 7wsm powder for velocity. I found it was .75 fps/deg but it was great with 180s. I did toast the barrel in 1500 rounds. I would have gotten another couple hundred rounds with retumbo, but I'm pretty sure I wouldn't have been getting the same velocity.

568 was a recent test. The velocity didn't agree with GRT and it would have required the same powder charge as Retumbo or more. I tried in the 7RM. And just decided to stick with retumbo.

N550 will be the fastest powder in everything from 243win to 3006. More than that you need to go up.
The only thing faster will be the other somewhat unstable double base medium kernel powder - RL17.

New Hodgdon StaBall 6.5 for the .243 Win is hard to beat speed wise!!!

thank you TRG for the rundown.

What cartridges did you find the RL 17 to be unstable?

 

[TRG65]

I forgot to add that I also use 555 in my 6mm creedmoor with both my 115 match load and my 90 sirocco deer load.

I meant temperature.
