I finally got my own chronograph and decided to try out my No. 1 in 450NE. Reloadersnest has 500gr SP with 105gr of H4831 at 2350f/sec. According to my chrono, mine was only at 2100f/sec. What is going on here?

2350fps with 105gr of H4831 seems a little high in normal hunting guns.

In your No1 2100fps seems well with in normal parameters for a 450 NE to me.

Remember, even back in the day most published NE velocities were from barrels 28 inches long...

Baised on my use of my 450 No2 on a bunch of different game animals, including several cape buff and elephants, a good 480 to 500gr Soft or Solid, as the case may be,at @2100fps will kill anything on the Planet, with no Drama.

In only ask because the Hornady manual has 94gr of H4831 at that velocity. I was hoping to get to 2300f/sec or greater. If I can only get 2100f/sec with 94gr of powder I dont really want to waste the extra powder with no benefit to velocity gain.

As you most likely know different rifles get different velocities with the same loads.

The only way to know is to shoot the load in your rifle over a chrono.

However I can say I do not see the need to get 2300fps with 500gr bullets in a 450 bore rifle for cape buff and elephant hunting.

IMHO all you are doing is getting increased recoil, and depending on the bullet risking bullet failure.

2050fps to 2150fps with 480 to 500gr bullets works great. I have used 480 Woodleigh Softs and Solids, and the 500gr Swift A Frame on game in Africa with excellent results.

My 450gr North Fork bullets go @2200fps out of my 450 No2. They kill extremely well.

I will have to admit that I pretty much bought the rifle for "increased recoil". The gun serves as my stress reliever when I get pissed off at the world. I do understand the whole different rifle/different velocity deal but to be off several hundred feet per sec! I am guessing that I am loosing velocity to a large amount of powder not being burned. That being said is there a powder more suitable that would fulfill my velocity needs/wants?

I am no expert but I thought that the Ruger No 1 action is designed for high (60,000 psi +) pressures and can easily handle those loads. The 2100 fps loads for the 450 NE were for Double rifles with less than 35,000 psi pressure.

Having said that, the brass will probably fail first. If you use the modern premium bullets or cast bullets for practice, you should have no worries about bullet failure.

I would like some feedback on my comments as these are just some of my thoughts and not necessarily proven hard facts.

Also, increased recoil over a period of time, can lead to shoulder problems and detached retinas.

No matter how "pissed at the world" you get, you can kill ANYTHING on it with a 480/500 gr bullet at 2100fps... IMHO.

Reloaded some more rounds up with various powders that I had on hand. I learned 2 things from this

1. Shooting a 7.5lb 450NE off the bench is hard on the shoulder
2. My gun is supper accurate at 50yds. the largest grouping I had was slightly over an inch.

Anyway here is my data. All bullets were 480gr DGX. All were averages taken of 3 shots.

H1000- 100gr=1777 105gr=1912 110gr=1991
H4350- 100gr=2283 105gr=2357 110gr=2424
IMR 3031 85gr=2231 90gr=2363 95gr=2463
Varget- 90gr=2228 95gr=2340 100gr=2480
Vihtavuori- 95gr=2318 100gr=2437 105gr=2526
N540

thecanadian: I think what you need to do is stop and go out and get a whole pot full on insurance and put it in my name. I ran your Vargent loads and got 90gr = about 2375 @ 55,000CUP 95gr =2500fps @ about 59,000 CUP 100gr= about 2650 @66,000CUP. Those are CUP not psi. You have gone this far why not try a 100% load 103.5gr @ 2700fps and 71,000Cup. Unless I am missing something there is no way around it "you are scary"

And I am supposed to know how much pressure I am generating how? I dont have any fancy computer software to do calculations to tell me when my pressure is getting to high, I have to go by what is available to me, signs of pressure on the spent case. Non of the cases showed flattened primers, cratered primers, extractor marks or even split necks. If I was running such high pressure than surely I would have had stuck cases, the extractor on a ruger No. 1 is not that strong. However, all of the cases came out like they normally do.

Now that being said,given the information that you supplied (even though you were kind of dick about it) I will err on the side of caution and avoid that load in the future.

Those loads are outrageously hot for a 450NE and NOWHERE in the Hornady manual do they clain 2350 fps. I easily obtain 2150 fps in my double with 98gr H-4831 and DGXs.

thecanadian: I could not give a rats ass about you and your "lets loader till she blows" attitude. I am worried about the people that have to sit at a bench next to you.
