    I have a .270 savage 110 with a barrel that has a 1 in 10" twist. The barrel looks to be 22" long (not sure how to properly measure the barrel though). I am hoping to find some recipes that will get me off to a good start. My powder of choice is Reloader 19. I am hoping to be able to put 5 shot groups inside a quarter at 100 yards, but if not, would like to be able to get close as I can to that. Any help and all help is greatly appreciated. I am shooting off of home made rest on the front of the gun and a sand bag at the rear. Will enclose a pic of my home made rest.

    Yep, use your manual to set a starting load and adjust to get the desired accuracy.

    If you chosen powder or bullet does not do want you want, you may want to try something else.

    Most rifles behave a bit different from other rifles so you have to work on your rifle's sweet spot.

    Sorry can't help you as I do not have a .270 that I reload for. Can only suggest you acquire a good manual ie: Lyman 49.

    Regarding how to measure the barrel length. With the action closed measure from the front of the bolt to the muzzle. Suggest using a cleaning rod and marking then measuring the rod from end to mark.

    I have a 270 Win with a 22" barrel, but rarely shoot it. The last load that I used was 55gr of Rel-19 with 130gr Sierra with decent results, but no chronograph. A 1in10" twist is the most common, and works well with many bullet weights.
    As others mentioned, a workup from a recommended starting load is best for checking for accuracy.
    You can try a few combinations of powder and bullet and find the best overall.

    If your asked what weight bullet for a 1 in 10" barrel I think you'd be better with a heavier bullet.

    My Winchester Model 70 featherweight shoots 140 and 150 Nosler btips nicely with RL19 and RL22. My best groups were with 51 grains of RL19 with the 140 grain btips at 5 shot .800" groups. I shot that load up to 54 grains and they all worked great. I shot that bullet up to 56 grains with RL22 and it was pretty hot but shot pretty well.

    The above works well out of my 24 in. 1:10 twist barrel. It kills deer like lightning.

    Buying good bullets will go far in reaching your goal.
    No matter what else you do to the load, you can't get great accuracy without great bullets.

    Unless you are trying to work up a big game hunting load?

    Try Plastic-Tip or Ballistic-Tip varmint or Match bullets from Hornady, Nosler, etc.
    Or any name brand HP Match bullet.

    You might find a SP big game bullet that will do as well, but it is not nearly as likely.
