I just reloaded my first shells for my 270 and found out what load is best. My best group was about 1.25 inches with for shots at 100 yards.
What is the nest step to get a tighter group? Should I make the oal a little longer to try and tighten them up or make it less.

I am using 130 grain bullets and IMR 4831 with 56 grains.

Any help is appreciated.

Did you start with a minimum powder load if so you could start working up by 1/2 grains to see if your groups get any tighter (do NOT exceed your maximum load data and watch for signs of pressure). Once you have worked up or down to find where they group the best then play with OAL.

What rifle? what bullet? what brass? what primer? Is the rifle bedded? what scope? how long between shot/groups? Sporter barrel? Too many unknowns to answer your question;)
 
if your shooting with a sporter, are you letting your barrel cool down between shots? When developing loads for my hunting rifle I like to do timed groups. I take one shot wait until the rifle is cool and take another and repeat until done. It takes a long time, but for hunting you first shot will be cold barrel. When I shot quick five shot groups with my 7mmRM the barrel heats up so quickly my POI changes very quickly and this can give you a false idea of how good your load is. When I switched to timed groups, they shrunk dramatically and gave me a better sense of what my loads were capabale of.
 
Also, is this one good group, or was this the average of several groups. The other advice is good, but before you chase rainbows, you need to know if the rifle and you are capable of shooting consistent groups. If you are consistently shooting 1.25 inch groups, then you can start playing around with the rifle and the loads. If it was just one good group, you may have a long way to go.
One data point does not make a trendline.
