Can anybody run Quickload for me?

[tinhorn97062]

I just got back from the range. I was planning to chrono some loads, but weather chose to not cooperate with me. Anyway, of the 8 that I tried, two of them stand out above the rest. I was hoping somebody could run these two through Quickload for an estimated velocity and pressure. They are as follows:

Marlin 1895 GBL .45-70, 18.5" barrel

first load:
Remington brass
CCI 200 primer
Lee .457-340 boolit, weighs 353 and sized at .460
IMR 3031 @ 44gr
COAL 2.54, firm roll crimp

second load:
same as above, except using H4198 @ 42gr

The IMR 3031 load gave me a 5 shot ragged hole and the 4198 load gave me 5 shot 2" group.

A .458 350 (Woodleigh RN Weldcore) puts you at 20,665 and 1,576 with the 3031

The 4198 (I double checked) puts you at almost 32,000 at 1,739 (According to quickload...UNSAFE for the Woodleigh I used in the calc. Closest I could find on the fly)

I'd have to build a profile for your specific bullet to get closer, but this should give you some idea what the different powders are doing.

I'd stick with the 3031!

When compared to the 4198, 3031 gave me better accuracy through all charge weights that I tested today. That 44gr load took the stage, for sure. I've read that cast lead moves faster than a jacketed, so I wonder if it's safe to assume I was in the 1650fps range?

Thanks for running the numbers for me!

The Lee bullet is .862" long. Using this length and 353gr weight but the profile of the RCBS 310gr bullet I get:

15191psi and 1463fps for the 3031 load

25220psi and 1683fps with 4198

The numbers are the same using the Lyman 330gr bullet profile at 353gr and inputting a bullet length of .862"

The Woodleigh bullet is much longer at .949" than the Lee at .862" At a given OAL of 2.54" this changes bullet seating depth dramatically and raises the pressure.

Quickload seems to know the difference between jacketed and cast bullets at least to some extent. Using the Woodleigh bullet and changing the bullet length to .862" still gives higher pressure but 28000psi for the 4198 load as opposed to 32000

Good call, Petroid! I didn't dig deep.....was in a hurry, trying to get supper cooked! Just wanted to give the OP a starting point for the discussion. I figured someone around here would set me (us) straight!

Guys, I really appreciate you taking the time to do that for me. I was hoping to hit 1650 with this load, and do so with accuracy and no leading. The 3031 gave me both, and the 4198 gave me pretty good accuracy with just a very slight amount of leading in the last couple inches of my barrel. I took the 3031 up to 50gr and the 4198 up to 42gr.

As as I double checked my notes for this reply, I realized that I gave the wrong input in my original post. The really good 3031 load was 46gr and the pretty good 4198 was 38gr. I kinda feel dumb for that error...haha. I still appreciate you guys doing that for me though, and I'll put it in my notes.

I don't claim to know it all and quickload is a very useful tool for R&D, but nothing is as good as a chrono and pressure testing equipment though. All this info must be weighed and compared to published info.

[tinhorn97062]

It follows along well with published data, as well as notes that I've previously taken. With that Lee boolit, I was looking for accuracy mainly. I wanted to drive it as fast as I accurately could, before the leading started, and I found the cutoff point. So- it was a successful day all around. That bullet seems to have a sweet spot right around 1500-1550 in my gun. Any faster and the groups opened up dramatically.

[petroid]

Sounds like you have a good load there. Without a gas check that may be as fast as you went to try and push that bullet

I just saw this post. Rerunning the numbers, I get:

46gr 3031 17138psi and 1540 fps

38gr 4198 19557psi and 1531 fps

Sounds like you have a winning combo with that 3031 load

I agree! Everything I use 3031 in just seems to shoot well. Thanks for running that again for me!
