which primer for varget ?

I am probably the only person is history that had a bad experience with a a Labradar RC but I would recommend making sure you get the American version and not the European. I had the European and nothing but problems, at least 4 of my cohorts have the American version and not a problem one.

@UncleNick, thanks for the breakdown on the numbers

A few years back I ran some H335 using identical loads and brass, the brass was LC 11. The primers used were all CCI and included two magnum types and two standard types. The CCI 400 and BR4 are standard and the CCI 450 and #41 are magnum. The rifle was an old Remington action I built up as a 223, the barrel length is 26". The date on the targets was actually June 1st and not January 6th as we don't have 73 degree F days around here in January.

The below spreadsheet reflects the velocity as measured about 15' from the muzzle using my old Oehler 35P chronograph. I was not really working on groups but trying not to shoot my sky screens.

The average velocities do not point to a magnum primer always yielding faster. The CCI #41 which is a magnum primer did yield the highest velocity but the CCI did trail the CCI 400 by a slight margin. The CCI BR4 primers did yield the lowest deviation.

The target was 100 yards.

Again, while the CCI #41 did yield the tightest group I was not focused as much on my groups.

My suggestion would be try several primers with your powder, bullet and brass and see what works best for you and your rifle. When I did this I expected to see a velocity difference much greater and expected the magnum primers hands down to lead but that wasn't how it played out.
