Need help with understanding my groups

[Chingon]

Check suppressor is tight, check action screws. Were scope bases/rings properly mounted with degreased screws and a torque wrench?

10 round groups are the minimum I trust for a solid zero. Same ammo lot if using different boxes? Lot to lot factory ammo can be dramatically different.

My experience is a thick barrel can keep a group. On the other hand my 700 mountain rifle with its pencil thin barrel will do exactly what is happening here.

It’s not meant to shoot groups with, it’s meant to be light and climb with. It prints a nice 3 shot but try and push it to a 5 shot and it will open up.

His is a 6lb rifle. Not sure what more he expected.

I’m not arguing your experience. I’ve had several pencil barrel rifles that would shoot the same size group regardless of spacing out shots or rattling them through as fast as I could load them.

Accuracy of the rifle is what is, and I agree a 6 lb rifle is harder to shoot than a 10 lb rifle. A good barrel will hold a group. A thick barrel that’s a true 1.5 MOA barrel will show this same trend.

All I’m saying is quit hunting for excuses. Find out what the shooter is capable of and the rifle. My Kimber is a 1.2 MOA gun, which doesn’t sound sexy but is plenty good to kill stuff and is well tested over a lot of rounds. Three shot groups look nice on paper and that’s about it.

What chambering in the rifle and how good of a shooter are you?

It’s 300wm and today showed me I got alot to work on as a shooter. I’m not a horrible shooter but not great.Ha

A consistent 1/2-3/4” shooter doesn’t ask internet strangers what’s wrong with their groups. Not throwing shade as Im not a consistent shooter either. Put some more rounds through it without cleaning and see what you get

Yeah I definitely need to just put in more time behind the gun shooting larger shot groups with more cooling time. I wish I was a consistent 1/2-3/4 shooter, I just didn’t understand the change

That’s a lot of cartridge in a lightweight package. Even with the suppression you have to remember that is not a bench rifle and quit expecting it to be one.

A lot of us have spent a lot of time and money trying to figure out what the change is only to realize it was us all along. Just know you’re in good company lol

I am with Addicting on this one. 26rd in a day out of a 300WM from a bench is a lot.

I’m a bigger guy who grew up on slug guns and 3.5in goose and turkey loads yet the 300WM wears me out from a bench.

However, worse than fighting the recoil, is fighting the heat. My barrel gets hot easy and my groups open up. I keep wet towels in ziploc bags in a cooler of ice and give 5min between shots. Also a suppressor significantly increases barrel heat.

Any barrel that won’t shoot tight until mirage off my suppressor (with mirage cover) impacts shooting is defective far as I’m concerned. I’ve owned too many that don’t have these “hot barrel” problems to think otherwise. It’s usually the opposite, shooting a bunch without breaking position = tighter groups because you’re addressing the rifle the same shot to shot.

That said, the two seekins 300 WM PH barrels I had wouldn’t do it but I don’t think it was totally heat related. But they got gone for a tube that worked like it’s supposed to.

If the barrel feels warm but not hot can it still be effecting poi?

If it does it’s a crappy barrel. More than likely it’s the nut behind the trigger or the barrel is just shooting what it’s capable of in real life.

Interesting, I always I have read heat will open up groups especially with light barrels
