Just watched this (Rob's Reloading on Youtube) and I'm curious about other opinions on whether Hornady might be pushing the pressures a bit. I'm shooting Hornady Grendel brass sized to 6ARC. My load is 29.5grs of LVR under the Hornady 105. Velocity is averaging 2570-ish from a 16" Lilja. No problems with my brass but I'm just starting my 4th firing.

Start low & work up! Peak load for one rifle may or may not be the peak load for the next rifle. So yes top loads may be too hot for some rifles while others where the throat was chambered like intended will do just fine with peak loads. Suppose I think of the throat in terms of Weatherby chambers that prefer lots of jump.

Looking at Lyman data vs Hornady focusing on Bolt gun data as that is my application, Id venture Hornady is not far off. My understanding is we should always start low & work up. Lot to lot of powder can vary. Barrels and chambers vary as well.
Never the less I was interested to compare Lyman data vs Hornady Data & see max powder suggestions , while close, they do vary with each source having somewhat higher charges depending on the powder.
So again, starting low & work up is as good as advice as ever.
