35 Remington - QL vs Hornady manual

[Nomad47]

In an effort to help BigEdP51, I did a little digging and here is what I found.

I have the 6th Edition of the Hornady two volume handloading manual. On page 538 of Volume 1 is the loading date for the 35 Remington and 200 grain bullets. My manual shows two 200 grain bullets - a Spire Point and a Round Nose. The manual shows 39.9 grains of W748 as a max load with a velocity of 2000 fps from a 20" barrel FOR BOTH BULLETS.

I plugged the info into my 3.8 version of QuickLoad and got some interesting results. The manual shows a .03" difference in COL and I kept that change in my QL entries. Of interest, even though the roundnose bullet is seated .03" shorter OAL, the bullet base isn't as deep in the case as the spire point. This results in more useable case capacity and therefore a lower case fill. The end result being quite a bit less pressure along with a 97 fps reduction in velocity.

The first image is the Spire Point.

I then went on to discover that increasing the charge to 42.7 for the round nose bullet yielded a max pressure of 40102 PSI which is just a tad over SAAMI max. And that is the max charge listed in the 9th Hornady edition.
So it would appear that Hornady tested the spire point for their 6th edition and the round nose for their 9th edition.
Conclusion: Same weight but different shape bullets can cause quite a difference in pressure and velocity due to the changes in useable case capacity. One more reason to ALWAYS work up.

and winchester puts both bullets at less than 40gr for max...

so again

always work up

I used to load for a guy with a contender and he was sold on h322 and boy was it accurate at a 100 yds.Not as fast as ww748 but it would shoot an inch all day out of that pistol.I am not saying to use it,but to me accuracy is paramount to all out velocity.

First off I want to apologize for being a grumpy old man last night, I was getting frustrated because I couldn't get the chamber pressures to match the powder charge weight. I thought with the shortage of powder and bullets I would be ahead of the game with Quickload.

After Googling Quickload tuning tips and doing a little web surfing it appears that accurate pressure reading are not a Quickload Strong point. My main objective was to find out AR15 loading information with carbine, mid-length and rifle gas systems and picking one load that would cycle the actions reliably at lower pressures.

Thank you Nomad47 for the tweaking ideas, by Googling your tips they sent me to the web pages below.

QuickLOAD Defaults (read Fred C. Dobbs postings below and what he has to say about Quickload chamber pressures)

I did find a good tuning sight, BUT without a chronograph I will never get the full potential out of Quickload.

I want to thank Bozo699 for offering to trade his 2010 Turbo Tax software for my Quickload disk, but I decided to pass and keep playing with Quickload and see if I can blow up my computer. :

And again, I do not have a 35 Remington, I was checking manual load data against Quickload output velocity and pressure. I would used the same velocity line in the manual for a given caliber and would enter each different powder type in Quickload and they didn't correspond in velocities or pressure.

Bottom line, Quickload wasn't designed for what I wanted to do and I should have asked here before buying the software. As I said above I'm keeping Quickload because much of the information on powders and other data is very useful. BUT I will need a chronograph to get the most out of it.

Some other things to double check,

Always check the bullet length YOU are using against QL lengths, I have found some big differences in total overall lengths listed by QL, in one case it was .100" shorter than the actual bullet being used, Horn 75gr Amax, as listed.

I was blowing primer pockets using an often shot safe load, and then found out the different in total overall bullet lengths.

Big ed,
Take your QL copy and look at the 300 Win Mag cases listed, per QL there is over a 10gr difference listed in the BRASS MAKE for the case capacities listed.

Do a test using these different case capacity's, quite interesting when the same load data is used for all of the cases!!!!!!!
Take the biggest cap case and run the load to the top yellow level (85%), then take this same load and run it in the smallest case capacity, now change the seating depth .100" either deeper or shallower. So many variables to deal with.

Do you see a BIG difference in PSI valves???

I personaly weigh the cases (for internal case capacity) that I am loading and then enter that data with the weapon I am using/loading for better results etc.

There is so much to tweak (and get better results) when using QL, and as Nomad said check the amount of powder burnt per BBL LENGTH, you can find a powder that will work with all your 223's, I know as I have 6 different 22-250's I load for, depending on bullet weight, 2 powders will work for all.

Tia,
Don

This is one of the reasons I was trying out Quickload, I have three five gallon buckets of once fired .223/5.56 cases. The Lake City cases aren't bad but the Remington cases vary from 90 to over 94 grains in weight and the case capacity varies greatly. With the Remington cases I'm loading 24.7 grains of H335 and using them for short range practice. The chamber pressure is low but Quickload shows the pressure varying approximately 5,000 psi due to case capacity differences.

And no I don't want to sort that many cases by weight.
