Thread: Load issues (blowback) 454 Casull

Greetings yet again Thatguy,
A bit more fossicking turned up a couple of old Winchester reloading components pamphlets. The latter recommended the standard Winchester small rifle primer and referred to the following warning.

Warning For 296 Powder.
Loads using 296 powder require heavy bullet pull (heavy crimp). Using 296 powder with a light bullet pull (light crimp) may result in squib loads and cause damage to the firearm, shooter and or bystanders.

Winchester also does not give any starting loads for 296. Their max loads are also considerably higher than the current Hodgdon data. Lil gun may be a better option but you may still need a crimp for best results.
Regards Grandpamac.
