Nosler Custom Brass

[Spino]

I'm new to reloading (8months) and thought that I would try some of the new Nosler Custom Brass. I'm shooting a 7mm 75 Sako Hunter. The reload components are scirocco 150 gr, Winchester Brass, CCI 250 primer & 65.5gr of RL-19. I have shot 3/4" groups with this. Moved everything to the Nosler Custom Brass = $43 box of 50 & my groups opened to 4"? Not sure what happened here? I checked the gun over for loose screws, but everything is secure. Any feedback on the Nosler Custom brass would be appreciated.

Thanks
Spino!

It is thicker/heavier brass. I had to drop my loads back a grain or two so I could keep the same pressure, velocity and group size. The same thing held in my 300 WM and .243. Drop the charges a bit, and I bet your groups come right back and then some.

Thanks for the tip & saving me time on this one! Ahh a glimpse of hope from an expierenced friend!

i would check the neck diameter of a loaded round and make sure it's smaller than a spent shell fired from the same gun.it's unlikely but a very bad scenario if your loaded round is pinching in the neck area.

second, i would load some in the old brass and see if it's still as accurate.as previously stated, you probably changed your velocity a little. try to get the same muzzle velocity and see if the accuracy returns.

Ok, reducing the load has helped, but I'm down to 62 gr. and still not where I want to be. I'm shooting about 1 1/2" groups. I don't have a chrony. Should I continue to reduce my load? Am I sacrificing velocity here? Help!!
