[remmag]

Ok got almost everything
loading 7mm rem mag using barnes tsx 150 grain bullits, I WILL BE STARTING WITH THE MINIMUM LOAD
their load data calls for federal 215 primers, cant find them locally
i do have some winchester wlrm primers at home
would i be safe with this substitution , is there a chart to help with this

thanks guys

I have reloaded well over 20,000 rounds in the past 6 years and can't always use the primer that the recipe used so I start at or near the minimum charge and work my way to or near the maximum while watching for any tell-tale sign of an over pressure situation. Have you read up on what those signs are. If not then you'd be really lacking in safe reloading practices. I could list most here but every reloading manual has all of the signs and it would give a much more complete listing - including pictures.

For hunting rifle loads, Primers is primers.

The Fed 215 is a Magnum primer, as is the Win WLRM.

If you get into benchrest competation with a benchrest rifle, it might pay to experiment with different brands of primers.
Otherwise, primers is primers, as long as they are the right size and type..

Here is a chart.

Since you are starting with the minimum load and assume that you are going to work up carefully, either mag problem will work. I too have loaded many thousand rounds and sometimes had to use what primer was available. However, my preference is for Winchester if given a choice.

Concur with rcmodel. I've been handloading for 40 years, and the difference between primers really isn't worth mention. If you start low and work up, you shouldn't have a problem. Even though it's wise and prudent to back off the maximum with any change in components...the primer brand is specified in the data because that was what they used, and is mainly FYI...not because it's a critical factor.

Time was that a "Magnum" primer would produce a little more pressure over a "Standard" number...but the difference really didn't amount to much except at the very top end load for a given rifle. Chasing the nth degree in accuracy is more likely to be affected by a change in primers...but even that difference isn't huge and not a concern except in the pursuit of reducing group size in increments measured in hundredths or thousandths of an inch.

Pretty much. Not worth chasing the tiny bit of difference they might make unless you are shooting some serious type of competition.

+1 on the above. Having been reloading for 30+ years, the difference between the brands for hunting or range use is minimal. When I cannot find my regular, I use what is available. If you were close to max, then reduce 10% but not with just starting out at min with a new load.
