Home Forums Hunting & Shooting Long Range Hunting Where's the node?

I started at 70 grains and ended at 73. I thought 70 would be a good place to start as I was using 77 grains with my last barrel.

Shows the difference between a worn out throat and a brand new chamber in regards to pressure with the same lot of powder.

I was just exaggerating to be an ass hole.

I don't know if anyone looked closely enough at the load data in the picture. it states a window from 73-76 grains of rl 33. I looked up the 6.5slr cartridge and I am hoping the OP just wrote the wrong numbers and is not trying to fit that amount if powder into a cartridge with 55grains of water capacity.

Different SLR.

you have a link I would like to check it out.

It's Rich's wet dream. 300 ultramag case necked down.

No, but I think the specs are written on an index card, stored in a mayonnaise jar under Funk & Wagnall's porch.

85grNBTat3500FPS,



You could use some logic and realize the 6.5slr could not push a bullet that weight that fast. Then you might ask a question like, "What is a 6.5SLR?"

Then I could tell you it is a 9.3X64 Brenneke necked to 6.5 with the shoulder blown out and some Weatherby radii added for beauty. The neck is about .300". The base is nominally .500". Once I had a fired case I discovered it holds 83.4 grains of water. That is very close to a .264 Win Mag.

I think this wildcat is number fourteen for me. The "SLR" stands for Sue Loves Rich and doesn't hassle him about his wildcats. Dave Manson of Precision Reamers name this one. The one after this is a 7RUM necked down to 6.5 with the shoulder pushed back about .100". It holds 109 grains of water. Ben at Hornady named it "6.5RUMLN.

I hope that clarifies things.

P.S. All the links are here on 24hourcampfire.com

Maybe didn't let the barrel cool down between ?

Strick9,

That test took two hours to complete. I believe the barrel is shot out. I ordered another yesterday when my shooting took four hours.

I hear ya Ringer. I saw some of your other ladders and they certainly pointed to some good nodes brother. I have had those days myself when no matter what I do , the node just won't peek out and smile.. What mfg tube are you going with?

That tube is a worn out Pac-Nor. I ordered a new one yesterday while at the range. They told me it is ten weeks out so I will take this rifle to them since "I'm in line" now with the 50% deposit for them to chamber and install it on my action. The quote is $650 including threading it for a brake.

Round count?

Somewhere north of 20 and south of 27.

You could have had a Bartlein barrel shipped in to you ups 2nd day...

mathman,



Around a thousand.

What?
This test mirrors OCW testing, not ladder testing, when is the node consecutive?
I must be doing it wrong!

Today I started with #6 which is 75.5 grains and dropped .3 grains for four loads. 75.5 produced the best of the four groups. Tomorrow I will fire four groups with four different primers.

Ringman,
If you tell me what cartridge, bullet, powder and barrel length you are using I can give you an idea of where your node will be from internal ballistics. With the last barrel I bought I had a load done in 20 rounds. I can get your velocities off your original post.

How many hunts has it been on in that time? Figure fewer than I would be happy with, but just curious.
