[QUOTE="wildcat westerner, post: 1481075, member: 21361"] Hello Sable tireur. I have owned several wildcats over the years and everything you wrote rings true to me. Your insights into the velocity previously stated would seem to be within the realm of reason. The statement about high pressures in AI cartrridges not being as reliable indicators that most use is brutally correct. Years ago, before I owned a chronograph etc. I used the flattened primer and bolt lift resistance as the indicators as to when to quit. I had built a .257AI with a massive steel sleeve around a Remington tuned action. Using RWS brass I decided to let my old methods tell me when enough was enough as to loading hot. Using target bullets I started with a load of 4350 that was suggested and I had my reloading tools with me and started adding a grain of powder. As the powder increased I noted the groups got smaller so it was easy to keep on adding to the load. The primers got flatter, but never did the bolt get any harder to lift after firing. I finally stopped when the groups started to spread a little bit. This was a heavy rifle meant for long range accuracy at that time. I drove home and looked in a reloading manual and found out I was shooting loads 6-7 grains over the maximum listed! Never again! [/QUOTE]
