223 and Benchmark

[kmw1954]

Help trying to find load data for the Hornady 68gr Match HPBT and Benchmark powder.

I have some previously shot targets that are marked as 68gr Hornady and Benchmark but I cannot find my other notes or even where I found the load data. This was a load I had just started on until I got sidetracked with a bunch of Nosler 69gr that I got a great deal on.

Anyone with a lead or a link would be greatly appreciated.

Wasn't able to find any for Hornady 68's but did find some for Sierra 69's at Hodgdon's.

There is over a 0.1" difference between Hornady 68gr and Sierra 69gr SMK.

So the bullet sets deeper so it's not going to have the same load range. May be over pressure at starting load with that much more bullet.

I did a scrub and found nothing...

I looked at Hodgdon's also and didn't see a load for heavy Benchmark. Will look again.

Yes the Sierra MK is shorter but at the same time I am loading it .060" longer than suggested length. 2.310" as opposed to 2.250".. Biggest concern is the bullet bearing surface length, which is much longer than the Sierra or the Nosler and RMR I have been loading.

Found data for TAC and Varget but both are a good bit slower than Benchmark going by some published data.

Appreciate everyones time to look.

After looking at Hodgdon data that has to be what I used but since I do not now have the notes I will run another ladder and basically start over. From the looks of the target I had only loaded 5 loads and just 3 of each.
