Well I gave up on this 7mm for competition so now I wanted to see what kind of velocity it would turn up with my old Hornady 162 AMX. This barrel is 30 inches long with a 1-8 twist the book says 71,0grs of RL26 for a 7WSM so I loaded up 68.5gr to 70.5 grs of reloader 26. I shot at targets at 365 yards. I am glad I said shot at because it wasn't very good. 68.5grs made it to the target and it was about a 2 inch pattern for 4 shots. saved one to check velocity. 69.0grs only 3 out of 4 got there
same thing happened for 69.5 and 70.5grs. Not to surprising since I have blown these bullets up before.
The 70.5gr load went a screaming 3410fps and that is still off the max load by a full grain or more. But those bullets will not handle that velocity. A Nosler 168gr Acc LRB will handle that much speed but the important question will they shoot accurate enough at that speed. This case produces more velocity than my old 7/300 Weatherby did which burned a lot more powder.
We only have one shooter on our 1,000 yard range doing any good with a 7mm caliber. Others have tried and all have given up on the 7mm for Paper punching. That's to bad there are a lot of new bullets for the 7mm but everyone got on the ultra long high BC band wagon and it ain't working. I shot the smallest group of our two day match with my Heavy 6mm Dasher using a 103gr Vapor trail which ahs a BC of .520 the group measured 5.045 for ten shots #9 cost me a bunch or it would have been a 4.2 inch group.
