Lately I am having this thing for .375" cal rifles and have been looking at the 376 Steyr...

I already have a T/C Contender carbine 21" factory barrel chambered in 375JDJ = 260gr Accubonds @ 2300fps

Sold my 22" barreled Sako Hunter V in 375H&H to a buddy because he used it more and wanted it more than me and I wanted better than the 30-06 performance that it was giving me, don't get me wrong it was amazingly accurate I just wanted a .375" cartridge that gave 300 Win Mag performance.

Purchased a 26" barreled 375RUM WOW now that is an awesome cartridge I get 3020fps with RL22 & 260gr Accubonds and settled on 2750fps with 300gr bullets.

I've now modified another 375RUM to far shorter 21" barrel and with RL17 get 3030fps with 260gr Accubonds and stopped @ 2720fps with 300gr bullets.

I have now been thinking that I would like a .375" cartridge that gives me velocities 1/2 way between the 375JDJ & 375RUM and I have been looking at the 376 Steyr cartridge.

So here is my question does anyone here have any experiences with it or thoughts on it?

If I do this I will rebarrel a Rem 700 LSS in 30-06...
 
To me it offers no real practical advantage over the parent Brenneke case. So basically it is a Brenneke in .375 caliber, giving it similar ballistic numbers.

If I was to build a regular length action .375, I would definitely build a .376 Steyr over the other choices.
 
I have a 375 Whelen Improved. Love it. Have had it for more then 20 years, built it myself with a 26 inch McGowan barrel on a 1908 DWM Brazillian mauser action. Very versatile and very efficient. PM me if you need more info but I think you'd like it.

Rebarreling to a .375 Hawk may be a better idea. You'll never have any issues finding brass, and the performance is almost identical.;)

That is an excellent idea I have been looking at the 375X06/Whelen/Whelen AI but they only give about 80fps faster velocity with a 260gr bullet than my 375JDJ so I wasn't interested in them.

I next looked at the 375 Hawk/Scovill though it gave the ballistics I was wanting I understand I would have to fire form the cases and I didn't want to take the time to do that.

The 375 Steyr though probably tough to find brass for gave me what I was looking at in factory available brass which is why I was looking at it.

Some how I had missed the 375 Hawk that is built on 280 Rem brass this maybe exactly what I want I'll look into this one a bit more.

Failing the 9,3's as a choice, if it has to be a short .375 , what about a .375 Taylor? (of Ruger)

I thought about a 375 Taylor but didn't want a belt.

Oh man I had to laugh at that... :D

Both the H&H/Ruger both produce higher velocities than I am wanting in this rifle basically a 260gr Accubond/270gr Hornady spire point @ 2550fps - 2600fps is what I am looking for.
 
Depends what your actual application is going to be, but......if you re-barrel your Rem700 to 9.3x62 and use 270gr. Speers, you'll get close to 2450fps. Other bullet weight choices, 232gr. Norma to 320gr. Woodleigh. It's .366 vs. .375 but with little fuss and muss other than installing a new barrel. Brass and dies readily available and very inexpensive compared to any of the options mentioned so far.
 
Just saw that I will have to fire form brass for the 375 Hawk which I really didn't want to do but I really like the idea of using 280 Rem brass.

Whelen/Whelen AI = 30-06 brass
Hawk = 280 Rem brass
Hawk/Scovill = 9.3x62 brass
Taylor = 7mm or 338 brass

How readily available is the 9.3x62 brass I have never looked for it before?
