I used a 35 Whelen AI for many years. My favorite loads were worked up like I would any standard round. Back in '95 I added powder until the bolt was stiff or primers got flat then backed off to best accuracy. I always used new, fireformed brass for hunting. While I never had an issue with those loads, while checking the h2o case volume, powder charges, etc on Quickloads I found I was running them right at ( QL guesstimated) 72K! I have a repaired retina in my left eye, and I am very protective of my good shooting eye, I wear glasses, but all it takes is a blown case head/primer and I "risk" that good eye. Unacceptable, especially now that I "know" I was running that hot. I definitely liked how the rounds killed at those speeds ( 2970/Barnes 200X & 2600/250X, 250PT/2750) from a 22" barreled Mod 700 Classic Whelen) I made the decision and had that rifle converted/rebarreled to the 358 Norma Mag. I wanted the velocity but in a bigger, established pressure SAAMI round. It turned out swell but it got sold during a financial crisis ( Obammacare extortion/shakedown) I finally picked up a Mod 70/7x57 and an older Ruger 77/338WM. Both have established pressure limits/loads. Anyhow, if I have another rifle built, I am tempted to try the 280 Sherman ( "maybe" 6.5) but...I'm concerned about the pressure. I find the almost straight case/sharp shoulder cases don't show "typical" pressure signs; when they do they are "hot", ha. Anyone know just how to keep them loaded safe ( all the design will safely do is what I mean, not milktoast loads) or do most guys just run them hot? I'm curious...thanks guys. Jim
