Yes it is a hot load, but a Ruger no.1 and most Bolt guns can take just about anything out there. I believe the Max load in the Sierra manual is around 56 or 57 grains of R-22. A case that has more air space is more dangerous than one that is full, besides a 223/5.56 is running in the low 60,000 psi and a hot 25-06 isn't even close to that but like I said there weren't any pressure signs to worry about. I also built me a 25-06 AI on a Winchester M70 push feed, Schneider 1-12 5p barrel, McMillan Stock W/Burris Scope. Another nasty cartridge and a lot of trouble fire forming and working brass etc. etc. so I am going to re chamber it to 257 Weatherby.
That 85 grainer is a nasty bullet. I built me a 257 Weatherby on a Remington 700 action, Schneider 1-12 twist 5p 28" barrel, McMillan stock and mark 4 Leupold scope and the ground hogs in Caroline County Virginia hated that rifle. The 85 gr Nosler Ballistic tip would make a mess out of a ground hog. I also used it in Africa on a plains game hunt with the Barnes XLC 100grain bullets. I like anything 25 caliber.
