375 RUM Info
Decided to go with the 375 RUM build. As I mentioned in my other thread 375 or 416, it will be a singe shot Savage. Any input welcomed. Bullets, barrel length, any successful loads. You don't need to list powder amounts just manufacture, bullet make, COAL just a good start would help. Thanks
 
My first .375 Ultra I carried for more than 200 days a year and shot frequently. The short 20", fluted barrel resulted in a slightly clubby feel, but not so bad that I couldn't handle it quickly or shoot it straight. I shot just about everything through it, from 260 gr BTs and ABs, 270 gr Interlocks, 270 and 300 gr Xs, XLCs, TSXs, mono-metal solids from both Barnes and PMP, and a couple of heavy weights, the 350 gr Woodleighs and 380 gr Rhinos. Across the board, I got the best velocity with H100V, but most of my loads were worked up with H-4350 and H-4831. I'd stay away from powders that need to be heavily compressed like R-25 and Retumbo. Cast, or inexpensive jacketed bullets can be loaded over light charges of Unique for small game shooting, I was getting 1200 fps, and ptarmigan hit with them looked like they had been shot with a .22. COAL was never a concern, I just seated my bullets to the cannelure and crimped them. This thing shot like a varmint rifle. My second .375 Ultra just got finished and is on its way home, this one has the factory Brno barrel cut to 22" which I hope moves the balance slightly forward.

Some elements that you might consider for your rifle include a knuckle deflector behind the trigger guard, a good quality recoil pad, and in the case of the Savage, a heavy weight stock. Place the front sling swivel on the radius of the forend tip to prevent getting cut hand, and instal a Picatinny rail scope base so you can mount your scope well forward to avoid getting cut, particularly if you intend to shoot from low supported field positions. I had a custom quarter rib that was inletted for QD Tally rings and used a scout scope on the first rifle, haven't made up my mind about glass on this one. Beware of using low mounted iron sights if your stock has a high comb, that thing will loosen your fillings.

Cool build, and that must be a hell of a gun in a short barrel sporter Boomer. I think I would get a flinch shooting that after a while.

Where did you get your ching sling at BTW? Ive been tempted to try them.
 
The Safari Ching Sling quickly became my favorite. My first one I got from Gunsite, and its embossed with the raven logo, but post 9-11 Gunsite will not ship outside the US. I have bought a number of subsequent slings directly from Galco International, sans the Gunsite raven, and their service is excellent.

The recoil with that rifle can be quickly adapted to, and I had no difficulty holding 5 rounds from prone, that compares with 3 for a hot loaded .416 Rigby in a Ruger #1. The key is to never allow the rifle to hurt you. The report from the short barrel actually sounds good, not like the sharp crack of a small bore, but in a situation without hearing protection, its best not to shoot into the wind if it can be avoided.

A knuckle deflector! I'd never heard of that until now.

My Rem 700 XCR has a double layer of band-aids on the front of the trigger guard, as I figured it was easier to put a couple there than keep putting them on my finger. My trigger finger kept getting torn open by the floorplate release inside the trigger guard, when I was firing.

My stock (very light) XCR kicked like a mule until I put 40 oz of lead shot in the stock, held in with JB weld and crazy glue. Now it kicks like a .338 win mag, which is fine.

Most guys report excellent accuracy with the .375 RUM, as can I. Mine also is very easy on brass, even with heavy loads. Brass flow is almost zero. I've been using the same batch of 40 brass for a very long time.

With 300 grain TSX's and IMR 4350, my rifle (24" bbl) can get an honest 2950 fps; seems guys on the internet with 26" bbls can pretty regularly get 3000 fps, which seems to make sense to me.

I inherited a couple of boxes of 270 grain Hornady spire points, a classic .375 bullet, and I've been using them as a general purpose bullet, loaded a to moderate velocities. I've been very happy with them so far.

I tried IMR 4831 and found it to be terrible in my rifle, with all sorts of ignition problems and dangerously erratic performance. I would strongly suggest staying away from it. Next thing I'll try in mine is RL-17, which I have found is a great upgrade for most cartridges that have classically been used with 4350.

My 375 rum is a custom built rem 700 with an HS thumbhole stock. Which seems to help with the recoil and stops my hand from ever sliding. Scope is mounted normal distance. Never had a problem with the scope getting close to my eye.
