View attachment 124012 View attachment 124013 Hey guys, I know there are some very knowledgeable reloader son here and I'm scratching my head today.
Rifle, 28 Nosler Christensen Ridgeline 1:9 26" barrel
All shots at 200 yards. Light and variable wind.
I went to range this morning with several loads to test. Shot some and had an incredible group with 175 eldx 77 grains of H1000 had a 4 shot group .75 moa that is including the one I might have pulled with a sd of 11.6
That is really good for this rifle so I run home and load some more to see if I can repeat. Head back to range and get 4 shot group of 1.85 moa WTH??? but still have a good sd of 12.4.
This was all using brass sized at the same time, same way, from the same lot of Nosler brass on its second reload.
I'm really scratching my head. I really thought I had this and now I'm just confused and aggravated. Any ideas??
Fortunately I also had some hammer hunters that I also tested and they seems to be shooting wonderful, so I know it's not me, optics, etc. Hoping someone on here will have some suggestions on why this load did so well 1 time then went to crap a couple hours later.
I had problems in my custom 7x57 with the 162 grain ELDX. It's the projectile. The combination of muzzle velocity, barrel length and flight time to the target it what causes it. The plastic tips are melting..... Hornady denied it to me. 100 yards they shoot like a dream.... Scratch your head at 200... 300 is *** shooting and 400 cant hit 8" silhoutte... I called Hornady they claimed every thing from my loading to how my rifle was chambered. Funny thing is I dont have that problem with 160 grain sierra match kings. The rounds where pushing 2840 FPS. I would imagine your Nosler is faster... So the as your projectile flies the tip deforms more... Further the target the worse the groups. I loaded up qty 100 and was so disappointed. Hornady didn't offer me any compensation. My rifle also has a 26" barrel longer barrels transfer more heat to projectiles.
