Tested the Merkel today with 286 Privi Partisan, Norma Cases, 210M primers, and IMR 4064. I started at 53grains, and increased by .5 grain until I reached a max load of 56.5grains, and loaded four of these. The picture below pretty much tells the story. I should note that all the shots were taken from a bag but the last three, which were taken with my elbows rested on bags, but my hand unsupported. This changed the point of impact.



The max was about 100fps lower than max V in Nosler’s manual, but their data was taken from a 26†barrel. Mine is about 23â€, and I figure roughly 25fps per inch of tube. My data seems to be very close to their data.

I’d like to thank those of you who provided much needed info and suggestions. They worked. Other than PRE, which I don’t agree with (sorry), is there any other way to judge pressure in a double gun? Thank you again, Kudude.

I have had good luck with the PRVI bullets as well, however, based on questions I have asked here, I don't believe that I would use them in Africa.

Peter,

They are a fairly inexpensive bullet and 286grs; that is their charm for me. Kudude
