ballisticsstudies.com Or just google 7mm practical. Dave Manson has reamers and dies. Nathan Foster from New Zeeland is who developed the 7 practical and that is his site. I built one but have not shot it yet. Think I like is all the development has already been done. Get on his site. A good read and covers a lot of territory.There was a similar thread last month. You might find some good info in that one, too.

I've become quite enamored of the 7mm-300 Win Mag lately, mainly because I accidentally acquired an Ackley Rem700 in that chamber. There's about a 60 page thread on that caliber on here. I also believe the 7mm Practical is quite similar to the 7mm-300WM.
I am about to start a 7mm build. Keep in mind this will be a hunting rifle for 7-800yd max range. After running a 20" 6.5cm and loving the short barrel I am thinking about a 22" 7mm. Also I want to run the 180 eldm. I want to run around 2900fps. I was thinking a 7saum but recently saw Gunwerks building 22" 28nosler rifles. What are your thoughts on a 28n with a 22" bbl??
Keep in mind a couple things
1: I don't care if it is a flame thrower out the end of the barrel.
2: I don't care if the barrel only lasts 700 rounds.
3: I think I can run a little faster powder (4831sc vs h1000) to optimize the short barrel.
I talked to my builder two days ago about a 7-300PRC... I would be interested to hear data from anyone that has built one.how is the 7-300 Sherman coming along ?
Or is that the 7 Max you speak of
I'm dying to build a 7-300 PRC
Doe taken at 525yds yesterday with a 180gr eld-m out of my 7 SS with a MV of 2900fps. Barrel is a 24" proof sendero. Entrance was on the back end of the shoulder absolutely destroying her front right shoulder she had nearly 360 degree movement after. Through both sides of the rib cage and exit. Didn't find the bullet. So can't really say just yet. I took a smaller doe at 378yds two days earlier she was DRT. This one remarkably ran about 20yds and that was it. But yeah the 180gr eld m at 2900 caries some serious energy out to distance. That BC and form factor no doubt seems to be true. Both my kestrel and calculators have been spot on with it.I've seen several people reference ELD-M's for hunting purposes. How well do they expand and perform on game? Does the tip initiate expansion like the ELD-X does?
I use the 162gr ELD-X in my 280AI and it's the nuts out as far as 1000M. Last week I took a 40-50 pound piglet at 675yds with it. Rifle is built on a Weatherby Mk-V action and I have a can on it. Great fun to shoot milk jugs at 700yds.
I do not know you or your works so this is not a reply on your abilities.With my customers I steer them to know what is right and what works. Not BS to fatten the checkbook
