I know this subject has been covered before but I'm too lazy to look for it. Anyway;
Sierra 69gr HPBT over 25gr of 748 does the trick in my Savage but these would not work in an autoloader...

Slug: Win 55-gr FMJ BT
Powder: 26.0 gr. Win 748
Case: Rem-UMC commercial and mixed mil.
Primer: CCI #400.
I have found this load more than accurate enough for bolt guns and more than powerful enough to cycle autos.
However, the first step in developing a load for any .223 or 5.56 is to find out what the twist rate is of your rifle's barrel, and then do some research on the range of bullet weights that your twist rate will stabilize.

I'm just starting myself and have only put out about 100 rounds. I'm using:
H-335 24.0gr
FMJBT 55gr.
WSR Primers
Very good accuracy from a 14.5" barrel, I don't have a velocity on them yet though.

Wow! That's hot!
I run an identical load (you must have X dies) but with CCI primers and 24.0 grains of H335.
24.5 grains of Varget behind a Sierra Matchking 77 grain bullet. I use standard CCI SR primers loaded into late vintage LC cases.
For a practice /plinking load I use various 62/63 grain FMJ and surplus WC844 powder with a CCI SR primer. Case headstamp vary but the load is accurate enough and no signs of pressure. I do prefer the Golden West bullets when available.

That's my SHTF load. @ 26.2 grains I start to get excessively flattened primers.
My target load is 25.5 grains H335 / HornFMJ 55gr.
I did pick up some Win748 under advice from a few members to try out.

What was the problem with the H335?
Any particulars on how it worked better? I'd be interested in how you compare the two. (of course I'm asking this after investing in 8lbs of H335!)
It metered better in my Hornady LnL powder drop, and the max. load was the accuracy load, which makes it a little easier to load both SHTF and fun ammo, as they're both the same. The drawback is that it generated notably more barrel heat than H335.
