New Longrange Rifle
This started a bit over five years ago when I was asked if I would like to order a BAT action.
The answer was a resounding YES!
Initially, I ordered two SV’s and a HR Lap boltface action. I was then asked if I wanted to order a Cheytac action, BAT machines their actions in runs of different models, they were doing a run of CT actions that could be included with my order, who am my to argue!
After a few years of stuffing around with the getting the actions they finally turned up.
I built one of the SV’s into my 20PPC, the other SV is in the safe, still procrastinating, it's a 223 botlface.
The HR Lap boltface action will be my Longrange hunting rifle in 338HCM, a long Lap improved case.
It was going to be 300 Norma Magnum Improved but I have started using 215 grain Berger's in my 300WM
that work very well for hunting to medium range.
The 300NM with 230’s would definitely be better but not by much.
The 338HCM with 300 grain Berger's is a much better choice.
The CT action was always going to be a 375 Snipetac, or so I thought, its a improved Cheytac case.
I did toss up doing a 338 Snipetac but I always had a thing for 375.
My Gunsmith, Aaron Jones at Precision Ordnance ordered a 375 barrel and T5 Terminator brake
and the wait began.
I also happen to have a 338 barrel with the correct knox size for the action.
During the wait we talked about what caliber I was going to do, I went backwards and forwards
between 338 and 375.
I always thought the 375ST was just to “close” for a better word to the 338ST, that is mainly due
to the 300gr Berger having a very good BC compared to the 350 SMK.
We talked about our options and said “why don’t we make a bigger 375 case”!
The first thing was the name!
After a lot of throwing ideas backwards and forwards between Aaron and I, we came up with,
375 Hellfire
Bertram had the head stamp made and started drawing the brass.
Once Aaron had the brass in hand he measured it up we worked out all the dimensions he ordered the reamer.
The case is a quarter inch longer than the CT-ST case, which does not sound like much but every other dimension a completely different!
Once the reamer turned up Aaron chambered the gun and test fried it before he set it to me.
I received the barrelled action and bedded it into a stock that was actually made by a AV member,thanks Alan!
I have done load development for my other guns but this was all new to me!
Bertram sent me some cases I loaded after talking to Aaron where to start and worked up.
We had a few issues, killed a few cases, had some more made, they were ok handled pressure better,
then tried the latest batch and they are awesome!
For a comparison, a Snipetac load is around 140grs of 2218 the 375 Hellfire load is 172grs 2218
so there is a fair bit more capacity!
I have loaded,
350 SMK’s Jacketed projectile
350CE MTH Monolithic projectile
375CE Laser Plastic tipped Monolithic projectile
400CE MTH Monolithic projectile
All the information for loads and speeds are on the Precision Ordnance Facebook page plus a few videos
of me shooting it!
https://www.facebook.com/precisionordnance/
As most here know I own a 375 Cheytac, some have shot it, the Hellfire is a lot more gun!
It took me a bit to get used to the recoil but after 20 shots I was ok with it!
You certainly know your shooting it!
All this did not happen in a hurry, nothing dose in the gun industry.
It has been 2 years in the making!
Was it worth it?
With a 32” barrel I get 3520 fps with a 350SMK!
You bet it was worth it!
We still have a few things to sort out, reamer for dies to come and I definitely need more
barrel length, as you can see by the photo below, the next one will be 36”.
I do have a McMillan stock on order to replace the big BR stock because it will be used as a long
range Sambar gun but the BR stock was perfect for testing!
We are working on the 338 Hellfire now!
I will be ordering a new action, barrel and stock for the 338HF.

Re: New Longrange Rifle
Thank you Trevor!
This only happened because 12+ years ago, wow that surprised me, I logged on to this forum!
All I wanted to do is build a, one off, varmint gun
Here we are a dozen years later!

Re: New Longrange Rifle
Well done Glenn, have seen a bit about it on Facebook, didn't know that it was your invention, will have to go have another read all about it. That stock will be way more useful for you than it would have ever been for me.
Congrats mate.

Impressive.
Although I am not too proud to admit that it is too much gun for me...

Re: New Longrange Rifle
mistit, still have the 338 to do.
I will be interested how far too mate.
Thanks Mark, I won't work!
Thanks Camel, yeah I meant to say thank you for selling me the stock!
It is perfect for testing!
The action fitted up really well.
Thanks Keith, Aaron and I talked at length about how fast we would get, I have always aired on the
conservative side, not wanting to be disappointed! I was hoping for 3400 fps so to get 3500 fps was spectacular!
I am a little excited to get the 36" barrel, 4inches of barrel will give me a little more speed!
I could go longer but then it loses practicality for a longrange Sambar gun.
Thanks Rabbitz
After the first few shots I was starting to think the same!
It's ok now.

Re: New Longrange Rifle
I think I said before Glenn, that stock would probably been a waste with me, I am glad it has gone to a good home of a bloke who will appreciate Al's excellent work, and will get a good use out of it.
Going by the size of the new barrel you are planning on getting, it wouldnt be out of place on a machine gun mount on the back of a ute, save you carrying it around.
