Well, I had a death in the family  :'( and was off line for a while, but I finally got to test the HDY 88gr  ELD-M / Alliant PP200-MR combo today. I used the top four recommended loads in Hornady's published data: 24.3 gr, 25.3gr, 26.4gr & 26.9gr. The 25.3 gr load was the clear winner in my rifle. It put 4 rounds into 0.315" @ 100 yards, but I had the inevitable flyer with the last shot that expanded the final group to 1.185". I swear the last shot jitters on a really good group is pretty much the same disease as deer fever. Lol! This load should give 2600fps in my rifle. Will chrono it at a later date.

The 24.3gr load was all over the place. 26.4gr was even worse, but with slight ejector marks. 26.9gr tightened up a bit, but worse ejector marks and some primer flattening.

I also have a sanders upper. But the 88s in mine touch at 2.325 so I loaded 2.290 to see how they do. Havenít got to try them yet I may get out tomorrow

Interesting. What are you using to measure chamber depth? When I first loaded for this rifle I measured the throat to be a bit longer. Don't remember exactly what it was. When I loaded ammo to jump .02" using that measurement, they went into the lands and they wouldn't go into battery. Had to pry the bolt open, and sure enough, marks on the bullets showed they were into the lands. I switched to a Hornady OAL gauge, then I measured the throat with the 88's at 2.295" (avg.). Sanders doesn't give out the maker name of their barrels, so there's no way to know if we are looking at two different barrel manufacturers here, or what. Like I said, very interesting.

Had some time this morning.  88 ELD @2.280 with 24Ē sanders armory upper velocity 3lb trigger.  Seems to like the 88s better than the 80. Last pic is a little better visual 4 under the penny I knew I pulled the 3rd shot
