In practice, there is a slightly thicker wall in the .284 which reduces the case capacity a little. That results in higher pressure all else being equal when translating Hornady brass loads to Winchester. Drop back a grain and retest. If you use a hot small rifle primer like the Rem 7 1/2 (personal favorite), WSR, or GM205M, I doubt you'll see much performance change with a large rifle primer, given the fast powders (by rifle standards) we are using.
Use the "search this forum" feature about 2 years back for a thorough discussion on the difference between the two brass.

Slightly off tropic, but related to your last post:
In a couple of my adventures with the 450B and other cartridges in which the primer went off but the powder did not, I''ve noticed that the powder lost its graphite coating and appeared as yellowish grains, which I understand is the native color of nitrocellulose. I''ve read reports in other forums making the same observations. Did this happen with your incident? Just curious.
(And for the uninitated, note that the click with no bang is a significantly undesirable result of pulling the trigger. When powder does not ignite immediately, it may still ignite later and produce some very high pressures. Tim/wildcatter has been warning about this in the forum since the forum began three-plus years ago.)
Do you have any idea what might have or probably did cause the failure to ignite that you had?
Just wanting to learn as much as possible from your incident.
