Re: Too much for a 1903?
Two things to think about here IMO.
1. What did they use for a test rifle, and barrel length etc. Not always what works for one or two rifles will be best out of another.
2. As long as you work up to that load slowly and wach for pressure signs you should be fine. I wouldnt recoment jumping strait into max loads, but there is a safety margin put into thier data. I would find a load that shot well without pressure signs, and play with seating depth to fine tune it. Not nessicarily go off of recomended load data. They recomend it for a reason, but I always use book data as a starting block.
If your concerned about the rifle holding up to hot loads, your not going to be focused on your shooting. Accuracy goes to crap for me if my mind is wandering off to other things.
Work up an accurate load, and fine tune it. You already have a great caliber thats fun to shoot, and forgiving to load for, and a quality bullet, and a good powder.
