Effect of loads that are too hot?

[5RWill]

Here's the load
45.5gr Varget
Nosler Brass
Hornady 178Gr BTHP
Fed 210m Primers
COL 2.860

So when i grouped these in low temps the best group i got was 45.5, which i accidently loaded from the get go (max is 45.2gr). That said i saw no pressure signs at the time or maybe i wrote down 45.5 when it was actually 45.2. Either way fucked up something this go around. So shot last spring and the first shot stuck. Decided to get rid of the remaining rounds i had left today. Was shooting out to 400yds and they were literally everywhere. Dialed 2.2Mils thinking it wouldn't be too far off my berger 175gr load and it was over. I ended up shooting 1.8 Mils and shooting high as hell, though still making hits.

None of them stuck, was just trying to get rid of them without having to pull them all. Can the pressure spike of a hot load cause this? They were all over the place i've never seen this rifle produce groups this bad at extended range.

combination of being out of the node, and the attitude of wanting to get rid of them

when you get to hot of a lode, erratic velocity swings and crappy accuracy are common in my experience. Even tho you did not have a sticky bolt I bet that lode made your brass grow at the web and your primmer pockets are a bit looser.

Get a collet style bullet puller, makes it easy.

You should never fire known-bad ammo "just to get rid of it".

Agreed, thanks for the recommendation of the puller, i'll be investing in one. I brought the puller incase the first shot i had a problem with i was going to stop and pull them all. Dumb of me on account of my laziness i guess.
