I saved these trigger instructions off the web years ago for a friend with a .223 Howa and it worked for him, although he didn't have to adjust the sear engagement. His rifle, with me shooting, would do 3-shot cloverleafs at 100 yards with South African battle pack ammo. Yes, the barrel does heat up, so I was just shooting 3 fast shots off bags. John

The Howa trigger is adjustable:
1. Make sure the weapon is unloaded and remove the barreled action from the stock.
2. There are three screws on the Howa trigger assembly, all three are
RTV'd. Remove the RTV from the front and back screws.
3. The front screw is the return spring adjustment (Pull weight): Back
this screw all the way out, then install to at MINIMUM 1.5 threads. This
is the lowest trigger pull setting that is recomended by Howa. It will
give you around 2.5 lbs. Re-RTV the screw.
4. The rear screw is for Sear engagement. Adjusting this screw in will
give you a finer engagement and less creep (there is NO creep in my
factory Howa trigger), adjusting it out will give you creep. RE-RTV the
screw.
5. Reinstall the barreled action into the stock, place a stap cap (or
expended shell) into the chamber, cock the weapon and smake the rifle butt
HARD a time or two to see if you have gone too light on the sear
engagement. If you don't have any 'slap fire', your good to go.
