I was referring to the barrel. Man they are proud of them but if they work well and save weight I'll be ok. Now I have the barreled action decided on now I'm on to stocks. I'm looking at the manners eh5 cause it comes in really light for a thumbhole 27 ounces.
Proof barrels look great and man they´re light but... I just finished my 6.5 GAP 4s on a 24" proof barrel and it´s super slow. I´m getting 2920 fps using loaded ammo from copper creek topped with 140 bergers. I also bought 130 berger VLD ammo from them and it gives me 3050fps. I´m getting heavy ejector marks on the case and sticky bolt on both loads. I strongly believe that the barrel has to be very rough on the inside and that is slowing my bullets down and raising the pressure. Other than that, I can´t imagine what else can cause the high pressure/low mv.
It is a very accurate rifle (sub-1/2MOA) and it is super light, but my 6.5 CM launches the same 140gr bullets @ 2950 and does´t require that extra 50% powder.
