I have a question for those with more knowledge and experience than I do. Some background is that I used to use only factory Fed 165 Trophy bonded tip or Vortx 165 gr Barnes because it shot 3/4 MOA using those and I didn't reload. Occassionally I would find that some rounds would stick the bolt using factory ammo and forcibly struggle removing the brass. All factory ammo that I chronographed was around 3100 FPS to 3150 FPS. I figure maybe the chamber is dirty as it was usually after shooting alot. Could have been a "faster" round with more pressure, I suppose. For years, I used this ammo in this gun. Well, along came COVID19 and my favorite factory ammo is scarce and now appears to be extinc so I started reloading ammo for my gun. For the past 2 yrs, I have been working loads for various rifles so maybe 2500 rounds for so according to the number of primer boxes I used up. In all that time, typically ,if I got to max load for a particular powder/bullet combo the velocity was not up to that shown for the charge in the manuals. Well, that changed with my current setup using 165 TSX and H4350 and 68.0 gr powder. I reloaded some 165 TSX for my Fierce 300 WSM CT Edge rifle bumping the shoulder back 0.002 and trim to 0.010 less than max. I had a MagnetoSpeed on my suppressed rifle shooting that load and shot one round (not a clean barrel as 20 rounds were already down the tube previously using RL 19) I was shocked at the readout of 3260 FPS. I had to struggle to open the bolt. I thought, that is not right. SO, I shot another 3238 FPS, same result with the bolt stuck. Max load according to Barnes is 69.4 @ 3126 FPS with 24 inch barrel. My Fierce has a 22 inch barrel plus 8 inch suppressor. I seated the bullet BTO 2.230 while jam measures 2.335 for this bullet in my chamber (with hornady gauge). I shot one more and didn't shoot any more of those and then shot some factory Fed Barnes 165 TSX and the bolt was tight and difficult after shooting those as well. So I cleaned the chamber with a bore mop and shot factory loads again and ran the bolt more smoothly. I am somewhat afraid to shoot the remaining loads as the velocity is higher than I have seen in any other manuals. I started at 68.0 gr so I am moving down a few grains but I welcome any thoughts on this and why the higher velocity when not at max charge. Seating depth is my thought but IDK........ I will attach the fired brass which shows the ejector marks and primer.
