Harvey-- me too! Alas, the trip had to endDang... Wish you could hunt another month to keep the daily updates coming.
Is that book performance or what you actually clocked out of your rifle? 2650 is extremely slow for the bullet weight/type and cartridge. I have two loads in front of me clocking over 2800. IMR4955, 61 gr., 2828 fps. Superformance 59.7 gr., 2840 fps. Stats.... 24 inch barrel, Winchester brass, cartridge LOA, 3.3", lead core bullets.
On the hand loads-- I have clocked these but it has been a while. IMR 4064 48 grains is the max load from the Barnes book -- it says 2600 but I have a 26" barrel and that data is 24" barrel. I have not optimized the seating depth.
The Barnes load in the book has 180 gr over 60 grains of Superformance getting 2800 FPS, so I don't doubt what you're saying. But I did a final bench test with this load and could cover a 4 shot group at 100 yards with a quarter, so I stuck with it.
Good feedback on pressure, thank you.
