Before firing , the load chambers fine ...no sticking or tightness

If someone reads this and has a suggestion, I'd really appreciate it.

Thanks!!
Are you sure their loads have h1000 in them??

This sounds like high pressure to me; the round should show resistance to chambering if dimensions are off. You need to back of the charge and work up to just before you notice pressure signs and consider that your absolute max..

Pressure signs DO include heavy bolt lift. Triple check your dimensions compared to the spec's and factory ammo; if you aren't wonky somewhere your pressure is to high; probably at proof levels. Also either smoke or magic marker one of your loads and insert/fire the round. The marker/ smoke will rub of worst where the interference is.

Kinda wonder about the powder type as well. It sounds like high pressure node from any of the things mentioned. Sucks to have this stuff and it not be an obvious issue. On the powder side of things you may have to bump a powder weight way up in order to get the same results in FPS.

Case length
Head Space
Hot loads
Seating depth

I am sure you have thought of this stuff too, but if you can double check the case neck to shoulder junction and measure to case head. Compare that to a fired case and then resized case. You should see a difference in the numbers.

Re: Sticking bolt ....hot loads not the problem

I had this same problem with a remington 700 30-06. The problem was the brass had been reloaded to many times and so when it was fired it expanded the casing too much which resulted in my bolt sticking badly. So badly, that i literally and to reef
on the bolt as hard has i could in order to get it out. I started running some newer brass through it and didnt have a problem. Hot loads were not the issue. I was runnin 56gn. of IMR 4064 at roughly 3000 fps.

OK, WOW, 3000 FPS out of an 06. Even with a 150 or less pill that is amazing. That is 300 WM levels.

You think so? i didnt have any pressure signs. I thought about trying to push it even more but i figured that 3000 fps was enough.

Re: Sticking bolt ....hot loads not the problem

Well, I suppose it depends on the weight of the pill. It seems like with the same powder weight a 180 is was at 2750.
