In light of folks looking at loading with the primers they got on-hand, I thought this was interesting. Note that this worked for Red Dot and W-296. I do NOT in any way suggest that these results can be applied to any powder. Note also that John was using a cast bullet, which is easier to get going than a jacketed bullet.

"The Old is New" Handloads for a .41 Remington Magnum
by John Haviland [PBUH!]
"Thumbing through my chronograph records, I found the results of a comparison between standard and magnum large pistol primers in the .41 firing Red Dot and W-296 with the RCBS bullet [Ed. RCBS 41-210-SWC]. The results of shooting CCI 300 standard and CCI 350 magnum large pistol primers are listed in Table 1, and it shows no need for a magnum primer with a light amount of powder, but the additional 125 fps with a heavy charge of W-296 was well worth the added cost of a magnum primer"
