Another 338/06 QL Request Please, 210 TTSX?

preacher · Oct 28, 2023

I look up all Load Data I can, including Barnes. Unfortunately, I don't have any of the powders they list for the 210! ha Another reason I like QL is I can look at the Max pressure I am willing to use and the corresponding velocity. Its just another guideline I like to use is all. I have had some rifles that could not reach the upper limits and some wanted to go even higher. I also like to use the more temperature stable powders. I like to hunt late season antlerless for mule deer/cow elk, etc. I still like to observe primers/ bolt lift, and velocity to determine a loads safety in "my rifle". They are like women...every one of them is different, ha. Viva la differance!

I like the QL data too.I find it especially helpful when the data is inputted for your specs.It is also great when your working with cartridges that have very little data to go by.Here are a couple more pages from my Lee manual.They don't have data for the 210 TTSX,but is has a good amount of data for 210 jacketed.I'm like you,I like to know about where my pressures are

I was reviewing the QL data on the 175gr and 210gr.I noticed the QL for the 175gr showed Useable Case Capaci: 60.460 grain H2O = 3.926 cm³ and the 210gr showed Useable Case Capaci: 55.044 grain H2O = 3.574 cm³.
I saw in my Lee data for 200gr-215gr,H4350 was 62.0grs as a compressed load.It also showed the 215gr bullet at 59,900psi.The QL for the 210gr was showing 62.0grs would be about 80,000psi.I put 62.0grs of H4350 in a fired case I had.It would be a compressed load,but I could seat a 210gr bullet at that case fill.Could that be a case volume error in QL?

Some data in Lee's are not specific, but some show (example) xtp. Bullet length and bearing surface increase pressure. I do have a Lee manual, but wish they had a newer volume! Lee, are you listening?

I ended up using Big Game ( CCI 250) Lapua cases, with the 210 TTSX. Accuracy was just so-so until I got to 61gr, gave 3/4" for 3 and 62 gave and inch for three, but closer to my 175HH zero.

I'm going to focus some time on these three bullets/loads for now. I plan on zeroing at 100 with the 175HH indexing that with the CDS dial. Then seeing where the drops are at 200, 300, respectively. I have no plans, at present, to have a custom Dial made up for the 175HH load. In fact, I would have actually preferred this newer 2.5x8 didn't even have the gizmo on it, so may as well see what it will do for me.
