Home Forums Hunting & Shooting Long Range Hunting Which Big .33?

True, but a 338 Lapua, Edge, or Rum al have very close case capacity and if the barrel is not over heated will give excellent barrel life. My gunsmith checked the throat in mine after 500 or so rounds and he thought it still looked brand new. But I donot over heat the barrel when shooting.

With a good brake recoil is nothing.

Here's an oryx I killed with a .338 A-Square and the Hannibal rifle. The rifle weighed 11 lbs as is in the pic. Took it elk hunting once. The scope is a Leupold 3.5-10x.

IIRC the load was 121 grs of AA-8700,250 gr NP,CCI 250 primer for a velocity of 3120 fps from a 26" barrel.





Here's a pic of an cow elk I killed with my .338 RUM. Used a 210 gr NP at 3180 fps. Scope is a Leupold 3x-9x.

The shot was between 75-100 yds away.

That could be said for any cartridge.

I use the 300 grain SMK in my 338 Lapua in Lapua brass ahead of 92 grains of H-1000 lit by Federal 215M primers for 2800 FPS out of my Rem 700 action shot in a Rock Creek 5R cut riffled barrel 1 in 10 twist.
I went with the Lapua because of the quality of Lapua brass and the basil ability of quality match grade factory ammo.

I like the 210/250 Nosler Partition for the elk and such. As the area I hunt 200+ yd shot is not likely.

Right now,I load the 250 gr NP in the RUM,it's only going 2865 fps and it's a wee bit more accurate than the 210 gr NP I used on the cow elk in the pic above. Could get more fps,then the recoil become unbearable. Matter of fact,did get 3000 fps from a 250 gr Sierra,I felt like a punching bag for a heavy-weight boxer.

Nice.

Jeff,

No I haven't tried the Calvin yet, which is why I specified the standard Timney in my comparison I hear great things about the CE, but around here they're double the cost of the TT, and that's a hard pill to swallow considering how well the TT works.

And regarding the muzzle brake, here: http://precisionrifleblog.com/2015/08/21/muzzle-brake-summary-of-field-test-results/

Design of the JEC looks very similar to my Ross Schuler brake. I'd look up Ross.

I guess the TT triggers I've used and seen for sale in the local classifieds were imaginary?

Hard to beat a Shilen trigger in a model 700, unless one wants a trigger adjusted to ounces.

Jeff look at the Vais brake, turn it down to match your barrel and your all set!

When I built my .338 Ultra I had a custom barrel contour speced out so that the muzzle diameter matched the O.D. of a Vias brake.

Forget the Vais brake if you ever plan on shooting from the prone position. Ask me how I know!

Shooting prone requires a brake without ports on the bottom, unless you like crap blow all over you and your scope. I made that mistake just once with a 300 Rum and a Vais brake.

Ok, Vais gets checked out for sure. I've always been anti-brake, being of the mindset that I didn't need no stinkin' fire breathing magnum that required a brake..... haha.... so I don't know much about them. I was thinking Holland just to keep it local but whatever is "best"... I do know I will be shooting it from prone primarily so whatever I get needs to vent up and sideways but not down.

(Total side note: one RUM action donor candidate locally is a consignment 300 RUM LSS that's been Magna-Port'ed. If I went that route I'd at least shoot the damn thing on the off chance it had the kind of accuracy I need for this rifle.... being bought as a donor would GREATLY increase those odds, of course <g>.... so my question is, how well does Magna-Porting work? To be clear, the Big .33 is getting a BRAKE.)

You will want a side-discharge brake.


Unless this appeals to you,

I have never been too impressed with magna-porting, it does have a good effect on muzzle rise but not near the recoil reduction of a good brake. the worst thing is that it is cut into the lands and grooves of the barrel

The Holland Brake will work. For long range prone shooting a side port brake is the way to go with no ports on the bottom or top for that matter. A big 338 with a good brake will make accuracy much easier. If you run a long barrel (I went with 30") the exit pressure will be reduced and noise level will be greatly reduced.

Have a NIB HS Precision in 375 RUM. Great platform for making a long-range monster.

375 Rum with a 350 SMK would be a great heavy hitting long range rig.

Hey Shane! Merry Christmas.

I'm all about shooting out in the BLM clearcuts from prone rather than off a bench at a range, so yeah, a brake that did that would be a disaster.
