44 mag / unique / LPP

[Clickjack]

Really happy with my 44 mag load in my Model 29:
Missouri Bullet Company 240 grain SWC coated Keith style bullet
7.8gr Unique
Federal Large Pistol Primer

LPP ok with Unique? No reason to run Mag Primers?

That amount of unique is not difficult to light so yes a standard large pistol primer should be good. When you get up into the heavier stuff you might want to move up the primer. My Redhawk load is 19.7 gr of W 296 under a Sierra 300 gr soft point bullet and a mag primer, gets your attention when you light it up. Enjoy that light load they are fun to shoot.

Unique does not need or benefit from magnum primers in that load.
