26 nosler

[Bobcat sniper]

I started playing with my 26 nosler 30 inch 1-8 twist barrel and started with us869 powder I shot all the way from 84.0 g to 92.0 at 92 there was still not a lot of signs of pressure but the groups were not what I liked so ended up at 90.5 g at cold bore sight in at 100 yards this took a few days playing with loads so today I got the coronagraph out and sent 15 rounds though it this is the result in the picture yes that's right 3544 fps to 3621 fps It was 80 deg the day I shot this string using Berger 140 VLD

I was thinking maybe about tring something else in it maybe h1000 ?
Would you slow it down or leave it ?

No personal experience , but there are few powders in the burn range needed for this case. US869 is the most readily available. Your velocity is impressive but the numbers are a bit large for es and sd . H1000 and similar will be too fast. Good luck on your search. With your gun try to locate the Norma powders listed in the nosler data.. I have never ever seen them in person myself so they may be difficult,

Reloader 33 might be worth a try, it's inbetween H1000 and US869.

Wow that is hauling! 8)

Yes that's like 33 MOA at 1500

How hot was the barrel by the end of that string? That is a lot of powder! What are you using it for and how were the groups?

That is crazy velocity!

You're revvin' that 140VLD in the vicinity of 320,000 rpm. Would be curious to know if/how the 140 performs on big game under that stress...

HOT HOT if you look at the string it was expanding with every shot or that's the way I was explaining the increase with every shot
Lowered to 88.5 at 3500 fps this is group I just shot then ran out the door topic the kids up at school

As far as rpm on skin give me a day or two I will find something to shoot
Temp. Today wad 54 and raining

I would just go with it if it is shooting good....you will probably never get the chrono numbers that you want with that much powder it is going to get hot fast. Go by your groups and have fun!

I would try retumbo, its specifically made for the ultra mags and all the noslers are pretty much an ultra mag.
