Quickload request - 243 Winchester with IMR 7977

[1stpitch]

Hi guys. I'm a new member of the forum but have been lurking here for quite a while. I have a request right off the bat. . Could I get someone with Quickload with IMR 7977 data to run the numbers for 243 Winchester with 100gr Hornady BTSP #2453, with 2.650" COAL and a 22" barrel length?

Many thanks in advance.

I just received an update 3 or 4 weeks ago and the new IMRs were not in it unfortunately.

Here's a misc powder run on your setup though.

Cartridge          : .243 Win.
Bullet             : .243, 100, Hornady BTSP 2453
Useable Case Capaci: 48.905 grain H2O = 3.175 cm³
Cartridge O.A.L. L6: 2.650 inch = 67.31 mm
Barrel Length      : 22.0 inch = 558.8 mm

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 60000 psi, or 413 MPa
or a maximum loading ratio or filling of 110 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.

Thank you very much! I wonder how long it will take before the new IMR stuff is included?

 

[Dwh7271]

Don't know.
The new one had RL16 on it but not the IMRs. It's a puzzle.
I really want to mess around with 7977 and 4955. They intrigue me.

 

[jimbires]

man Dewey , I got excited when I saw you reply to this . I thought quickload finally got the new IMR powders . O well , thanks for the update .

I've been studying the data on 7977 and have come to the conclusion it's a virtual twin to re25 .... everybody's mileage may vary but I would use re25 data and work up comfortably for my purposes..... and I just checked my pamphlet on Hodgdon powders and it says 49 grains is max with a 100 grain bullet which is a perfect match to the ql prediction above.

 

[Dwh7271]

Good info kraky. Thanks!
Sorry Jim. No IMR yet. Don't know what's holding that up.

I understand the interest in the new IMR powders.
I am using an estimate of IMR7977 in QL using the burn rate for H1000 with the load density of IMR 7828. It's tracking well in my loads for the 7mm Rem magnum.
As far as the 243 Winchester, the new IMR 4451 is likely a better fit.
I have some rounds with IMR4451 loaded up in 243 Winchester, but haven't tried them yet due to having my affections alienated by a recently acquired 240 Weatherby. Will see how those work out.
