Case H2O Capacities

truck driver · Aug 27, 2015

I finally got to weigh some Remington Fire Formed 35 Whelen AI cases and they are a full grain less the the Nosler Cases. Will there be a great difference in my loads velocities and pressure in the Rem cases vs the Nosler?

Case weight is a full grain less or H20 internal case capacity is a full grain less?

Case weight is a full grain less or H20 internal case capacity is a full grain less?

The case weight, Remington is heavier with less internal capacity than the Nosler case which is lighter with more internal capacity.

Bonz · Aug 30, 2015

So much good 35 Whelen/AI stuff over here in the Nosler forum! Rodger, thanks for the heads up to come over and check it out vs "Shooters Forum" (hbonser over there). Finally have the fall hunting bug to get my juices flowing at the reloading bench.

I have a lot of 35 AI experience with traditional powders, and now have 3 new powders to give a try. You guys mind giving a fellow an assist with QL?

Bullet is the 200 TTSX
3.390" OAL
New-to-me powders: XBR8208, TAC and RL17
H2O fired case capacity 69 gr
25" bbl

Also, interested in the numbers for IMR4064, my current powder of choice.

Thanks guys! Look forward to getting more involved, let the best load be developed!

DrMike · Aug 30, 2015

Welcome aboard, Bonz. Always good to see other devotees of the shooting arts coming aboard.

SJB358 · Aug 30, 2015

Welcome aboard! Great to see another Whelen shooter...

If you don't have numbers I'll run them for you this evening.

Bonz · Aug 30, 2015

Thanks SJB358 and DrMike! Been a busy summer and want to dial in on which of the newer powders I listed is potentially the best velocity wise (compare to IM4064 as well) and start there for times sake. I am back at school full-time as a mid-lifer, getting my Masters degree. I.E. I would like to work each load up from the bottom, just short on time this fall.

My 35 AI: Built in spring of '02 by the late Norm Thompson (Colorado Springs area).
-M98 action
-Gentry 3-position M70 safety

-High Tech Specialties fiberglass stock, bedded myself
-Timney trigger
-aluminum (lighter weight) bottom plate and magazine box (capacity 5+1)
-Leupold VX-II 40mm, 3-9x

It's a total hunting gun, and shoots very well... Will post up some pics later.

Howard, glad to see you made it here. Lots of nice people will to help when needed and a very civil environment.

Bonz · Aug 30, 2015

Few pics...

300 yd target, 200 TTSX @2925 Mv, 3" high at 100 yds sight in. Small tear in target next to lower bullet hole is from peeling back the tape to take the pic.

Unfired and recovered 200 gr X and 250 gr X with 200 TTSX for comparison. Both went from stem to stern on elk, haven't recoverd a TTSX, yet, to put in the picture.

Last years elk, 241 yds 200 gr TTSX.

Great pictures and no better use of a Whelen!

Your going to like it here.

Case weight is a full grain less or H20 internal case capacity is a full grain less?

Click to expand...

The case weight, Remington is heavier with less internal capacity than the Nosler case which is lighter with more internal capacity.

Case weight has little to do with case capacity.

There is no direct correlation between the two.

Just because a case weighs more, does not in any way mean it has less capacity.

See here.

Example, the S&B case weighed 3.2gr less than the WCC yet they both had the same case capacity.

Weighing cases will tell one thing and one thing only, How much they weigh, It will tell you Nothing about internal capacity.

Bonz · Sep 4, 2015

SJB358, DrMike,

Wondering if you could run the numbers for the 200 gr TTSX with IMR4064 and also XBR8208, RL17, TAC? Trying to get a comparison of where I am (IMR4064) and what, at least on paper, might be gained by the other 3 powders using a relative comparison from QL. Want to take the best potential powder and start with it. Going back to school to get my Masters degree this year and just don't have the time to spend as much at the reloading bench.

Howard you case capacity looks a little light compared to mine at 76.13grs I would also check out the CFE223 for the 200gr since I'm getting over 2900fps with a AB and I'm not sure that is max yet but it is shooting good enough for deer so I'm going to let it go at that since I'm more interested in accuracy than velocity.

I question your case capacity. Case overflow is measured by using deoxygenated water and filling until you form a convex meniscus. Nevertheless, given the information provided:

Thanks fellows!

I read up on the QL thread today, and the only thing I didn't do when I gave the 69 gr capacity measurement to Rodger a while back was to de-oxygenate the H2O. I am doing that overnight and will measure tomorrow.

The step loading chart shows 57,000 psi, approx, as near maximum, and 60,000 psi as over max. Why not 64,000 psi as the max pressure, seeing as that is max pressure for many modern rounds in modern actions?

Forgive the questions, I have reloaded for a long time and stayed safe doing it, but with traditional info from reloading manuals and learning pressure signs over many years, and many guns, calibers, primers and bullet styles. Thanks for helping me get a grip on the QL stuff.

FWIW, my max load with IMR4064 with no primer pocket expansion after multiple firings or pressure signs upon extraction would fit into the chart (velocity-wise, 2925 fps) between the 58.76 gr load and 59.89 load, and I do that with 61.5/IMR4064.

Looking forward to re-assessing the H2O case capacity and going from there.

BTW, are IMR XBR8208 and Ram Shot TAC part of the database as it relates to the Whelen AI?

I set the parameters at 57 K psi to include the maximum number of powders. Default Pmax for the 35 Whelen Ackley Improved is set at 58015 psi. This can be adjusted to whatever pressure one wants to use. The differential in velocity between this setting and 64 K psi is actually quite small.

Yes, these powders are part of the data base. When I run the powders, I set the selection parameters at Useable Case Capacity of 112% and a nominal Maximum Pressure at 57200 to include as many powders as possible.

Howard I use distilled water that can be bought at the local dollar store or grocery store to measure H2O cap and also need it for my C-pap I also use a basting needle to fill the cases.
