I am also getting 3013 fps with the 175 ABLR and 78.8 gr of LRT. My barrel is also 22". Planning to take this load to South Africa next year unless I can get great results out of the 153 HHT.

LRT is a ball powder that allows you to get enough in the 7mm prc case. N 570 is about the same burn rate but an extruded powder so long drop tube and tap, tap, tap. Fast velocities with lrt and heavy bullets in the 7 prc but temp sensitive.

Is there a video online somewhere that shows how to undertake the modification and explains what is needed in addition to reamer. I saw the post from @charliehorse27 and can guess the tee handle and cutting oil are required but it doesn't sound like something to try myself without some further info. (I also noticed that the reamer from @charliehorse27 didn't appear to be the AW2 version shown in the earlier comments on 4 d rentals reamer)
I haven't seen a video anywhere but there's a good instructional on LongRangeOnly.com that breaks it down step by step with photos. I personally did not need to use sandpaper in the chamber to rough it up when finished.

The 7 PRC reamer I have is the 7 PRC AW reamer. To my understanding, they don't make an AW2 for this one because no modifications were needed to the original design from Alex Wheeler, like he did on the 6.5 and 300 PRC reamers he designed.
All that's needed to do the modification is the reamer, t-handle, and cutting oil. Barrel doesn't need to come off to do it, but removing the stock can help.

I'm a little confused. @Monteria indicated in one post that there was no AW2 for the 7 or 6.5 PRC versions of the reamer. However, his later post with the picture of the reamer shows AW2 and 4d rentals lists it as AW2 for the 7 PRC.
Your link to long range only was very helpful, thank you. It looks like something I could do. I certainly don't want to try pulling the barrel on my Seekins Element so glad it can be done with the barreled action.
I see what you're referring to in the post by @Monteria. The reamer he used was made by PTG and the ones I have are supplied by JGS Precision. I called Jasmine at JGS this afternoon and she confirmed my suspicions. She stated they supply and sell the 7 PRC AW reamer only (no AW2 version to her knowledge) because Alex used what he learned from the other two PRC's for the 7 PRC fix resulting in one final version. The AW reamer they carry is true to his specs for the fix. Perhaps PTG calls theirs a "7 PRC AW2" to be consistent with the names of the other reamers for the fix to minimize this exact confusion...?
I've done 3 Seekins Havaks and Element rifles now and my best advice is pull the stock off first and put the barreled action in a padded vise. They have a pretty high cheek comb and can make it a bit of a pain turning the T-handle.
There is another post here where I express my own dismay that PTG mis-labled the reamer. The one you want is Charliehorses. If I knew he had one, I wouldn't have rented from 4D.
Is 4D the correct reamer, yes. I simply prefer JGS and it annoys the heck out of me that PTG mis-labled theirs.

it's rather simple as the reamer is basically self-guided.

I'll be trying the Magnums with the N565 in the once-fired Peterson brass.
