7mm-375 build???

What is the quality of the Hornady brass?

I have no issues with it. Makes very consistent loads and holds up very well. Even the brass from loads that showed pressure signs during testing still have nice tight primer pockets. I would say it is easily as good as Norma brass. Definitely a step up from your average Rem, Win, Fed etc.

I got a screamin deal on my 375 Ruger brass where I only paid $70 for 200 pieces once fired factory test brass.

Another thing I like about the round is that forming the necks from 375 down to 338 is as simple as it gets. Just one pass in my Redding FL sizer die and done. I turn the brass 180 deg and make another pass, but you dont have to.

You are talking Gunwerks 7 LRM in reality. They have reamers, brass and dies in stock.

As for the smith go to Dave Tooley at Tooley custom rifles in Gastonia NC. He worked with Hornady already building and testing the 300 HSM (30-375) for Hornady (Hornady has the dies also already) and he has done the 7 and 6.5 versions.. He did a lot of work for them and AI in actually tests for the SOCOM sniper bids shooting the HSM over Doppler radar with the 338.

Yeah, i was also told that Dave Tooley was the man to talk to when I built my 338-375. He helped a little on the site here, but not much. I called him and got even less help. He said he wouldnt use a PT&G reamer, didnt know how to get dies, etc. Just a waste of my time really. I learned a lot more just reading about it from people who actually own one. So I ended up just buying my own reamer, from PT&G which made a perfectly beautiful chamber, and calling redding in NY myself to order the dies.

Yeah, he only uses Manson reamers for chambers and resize dies and makes his own dies.

According to him, the Manson reamers are supposed to be the "cat's meow". But they do cost bit more than PT&G. Dave Kiff has always built really good reamers for me so I decided to stick with him. I'm not sure that I could see a difference between the Manson and a PT&G in a hunting rifle anyhow. Benchrest rig, maybe.

Agree, that is a small charge for 2900+ fps and it is a very efficient case. The bigger ones really pull ahead when seated to a long OAL in a modified magazine and are propelled by a large charge of Retumbo.
Definitively something to consider in a new build. Could be useful in the .284 and .308 cals. also, especially in a 3.6" magazine.
The good thing about a hunting rifle is that you never are bothered by the recoil when a trophy is in your sights.

Correction. I just looked at my targets with all the data on them from the load I use. My charge is 74gr of RL-17. Not 72gr as previously stated. Still a pretty light charge for the performance though.
