And recipes for n550 in 30-06?
- Thread starter aroundpg
- Start date
VV550 is quite fast for bullets of the weights you suggest in the 30-06.
However, VV550 and IMR4350 are kissing cousins as far as burn rate goes.
H100V is closer, but there may not be any information in the manuals for this powder in the 30-06 with heavy bullets, because it like wasn't available at the time of testing.
I use IMR4350 start loads when working up loads with the VV550 I have on hand, with magnum primers of course.
I would say 150-165 grain bullets would be better suited to this powder.

Thanks! If I get velocity like that with accuracy I will be very happy. Trying both powders this weekend. Hoping for the best
2800fps with medium to heavy bullets is nothing to sneer at IMHO. I don't know of any game animal that will notice the difference between 2800fps and 2900fps even after velocity drops off at 300yds.
Not only that, but you're approaching the limits of your bullet's on target performance at close ranges, if you're using standard cup and core components.
To get that last 100fps, will require a huge increase in pressure, more wear and tear on your cases and more throat erosion.
It may also be very close to or even the sweet spot as far as accuracy goes.
I learned the hard way to quit chasing velocity and look for the best accuracy/velocity balance instead, leaning heavier on accuracy than velocity.
I like what you're doing, but would advise you to be more concerned with accuracy than velocity.

That's great advice. I appreciate it...
I am going to try to go up maybe a grain, but that 2800 load will be my focus next time I go to the range to test accuracy. Not using cup and core, think I'll be sticking with the 175 lrx, seems to shoot very well from my rifle.
Thanks again!
Monometal bullets such as the LRX work quite well and can be driven faster, but that doesn't always mean they will be as accurate.
It really depends on your rifle and tweaking the load, twist rate (they tend to be long for weight and may require a tighter twist to stabilize) but some rifles do shoot such bullets better when they're pushed faster, not all though, harmonics is a big issue.
One thing a fellow from this site pointed out to me when I was having issues with accuracy and monolithic type bullets, they shoot more accurately when there is significant "jump" before they contact the leade. He was correct, my groups tighten to sub moa out both of my 280 Remington chambered rifles.
I played with different seating depths, until the mating ogive is .100 off the leade.
