The bolt doesn't stick and no resistance at all, I tried using my micrometer to measure the case there on the web but I cant use factory ammo for reference since I use fire formed brass and only size the neck. I did use some of my once fired casings from the same batch as the now twice fired cases for reference and there was no difference if there is any variation its within .0005. My load data is:

Bullet: Sierra 165 grain BTHP gameking Case:winchester Primer: fed 210m Powder: 46 grains varget MAX

I used remington brass instead and a fed 210 primer also that is why I wanted to work up the load to be on the safe side since remington brass has a little less case capacity then winchester.

Asfar as the load data for a 150 grain bullet that you have 44.9 grains sounds like a start charge. All My data I have all shows 44 grains as a start charge for a 150 grain bullet with varget and shows 47 grains as MAX. that was both in Sierra rifle and pistol reloading data manual: 5th edition and Hodgdon's 2002 annual reloading manual.

Let me ask what would you do would you go ahead and use the max load or would you keep it backed off a bit? I was told by a friend here in arizona because it can be very dry and hot the max load isnt really the best idea because on hot days of shooting the barrel warms up faster and if I have nice hot barrel put a new cartridge in the gun and wait a few minutes before firing and the new cartridge with a max load warms up to the tempature of the barrel then you might have a problem and could blow the gun up when fired.

The chronograph I used in the begining to work up my load to the 45.5 grains wasnt very accurate half the time it would just read 0000 when shot through it, my buddy did tell me it was old and not very good. I'd like to think i was getting 2700+ fps with the 45.5 grain charge. Can anyone tell me that uses the same load as I do what charge they use and what kind of velocity they get from a better chronograph then the one i used. I know even with the same loads but different guns velocity can vary but I just need a general ball park idea. the velocity I want needs to be at the least 2700 fps.
