Ive shot the 7mm sierra bullets. The 197 were great but the 183 had different ogive measurements lot to lot it was horrible. They shot amazing but hated the change. Bergers just dominate

The 338 is a very good option but the recoil is noticeably more. You have to build the rifle a little heavier to settle them down. In general the big 338s will stay in tune better, have better barrel life, and be a little more consistent in day to day dope than big 300s will. The reason we all just dont shoot 338s is recoil and rifle weight to make them shoot well.
How often are guys retuning the 300 norma improved? Seems like the 338 is easier
Nope. I've pushed the 230 Hybrids to almost 3200 fps with no issues.
Glad to hear that. I will stick with 9 twist for future to help with that. That is smoking too I'm pumped
If you plan to shot heavy monos at any point I suggest you go with 8 or 8.5 twist. Mine shoots the 205 Badlands SBD2 bullets extremely well.
True. They make some awesome monos now
I've been firedorming my brass n565 83 grains berger 220 29 inch barrel avg velocity 3043. The fireforming load shoot pretty dang good going to take it to local elr league match
Once formed going to start at 85 grains and work to 86 and then 87 see what happens.

That's a pretty awesome load right there! How much do you really gain by pushing it past that node into a faster one besides more barrel wear, more powder, and issues if the temps get hot... I'd call it a day and go shoot!
