    The nose measures .301" the bore .300" it would not be a bore rider if it did not touch the barrel.

    It dosent look like your projectiles are seated too far out. Also those marks don't look much like rifling to me, looks like marks from the guide ramp or side of the chamber entrance.

    If you want to know how far the rifling really is try to work out your seating depth (One method):


    I think you will find there is still some spare space.

    its a good thing, the boolit is near fully supported and engaged with the rifling
    your powder choice for around 1600fps is a good place to start, which has plenty of power, especially with that boolit design, BIG flatpoints are deadly
    with the usual 1-10 twist of most.30/30s going over 1800fps accuracy usually drops off for most reloaders

    be interested to see what groups you get . .. do make sure all copper is out of the bore before you start

    A report on accuracy and performance would be good. Ive been shooting cast in various calibres for 45 years and enjoy seeing a shooter move into cast. If that is a Mihec mould projectile it should perform well up to 1800fps. Another great load especially for goats is 10grains of AP70.

    I have loaded up a few rounds this morning, there are 3-7 sticks of powder left in the barrel after each shot. 22 grain of 3031 put the first 2 rounds to the same POI with factory 150GR flat points. The third went low. Pulled the barrel clean after each shot, after the low shot I found the most powder. Name:  IMG_1346.JPG

    I think my powder is past its best before date, its one of those old tin containers. Am using Federal No 210 primers, never had an issue with it in my 308Win. The barrel length is 17 inch.
    Is it the powder or me doing something wrong?
    I have only a small amount of powder left so I don't mind buying something more suitable.I would like to have this a mild load. Liked the 20 grain of 3031, almost no recoil at all but left a fair bit of unburned stuff.
    Nothing is tough about having a 70 lb bow and looking like an uncoordinated praying mantis while trying to draw it back.

    Ignore the hole on the far right of the picture, that's from the 308Win. Forgot to cross it.

    Perhaps a powder with more density to fill your case and get a more consistent burn? Also could try magnum primers. Had the same issue with my 45-70.

    Slow powders like 3031 should not be used for reduced loads below what is recomended due to the possability of a S.E.E. . Better to use a faster powder like unique , AP 50, AP70, Bulleye ,even 2400 .This will give you a more consistant powder burn. Check out the castboolit website ,there is literally thousands of posts re 3030 .

    Looks more like damage from feeding to me.

    Your powder could past it's best I have an old tin of 3031 it is not working like it should as well, if you want to keep the velocity about what you are getting try AR2205 !6.0 grains will give you about 1500 fps and more pressure
    than 3031 and still be safe max load is 22.0 grains, 3031 is a good powder for jacketed bullets at factory type loads could be a bit slow burning for cast at medium velocity, got an email from a guy that killed a Fallow deer with this bullet at the weekend that's the third Fallow in a couple of months so they are working ok.

    They look like they shoot ok! Best advice is go to a faster powder, cast bullets dont give enough resistance to develop the pressure slow powders need resulting in partly burnt grains. This affects accuracy by giving inconsistent pressure between shots. I use 10 grains of blue dot or 14 of 4227 foraround 1400 fps with a 180 gr lee bullet and no gas check.

    Thanks guys, I will get some different powder.
    @shooternz I don't have any issue with the bullets , am just new to cast reloading that's why am asking so many questions. Did only 2 years of reloading before, the same 308 jacketed load what I got right the first time (by accident)

    I was due to follow up on the cast loads for a while now so here it is. Ended up with AR2207 so can use the same powder in the 7,62x39 too. Changed to Federal Match primers. After a bit of mucking around I got this with 17grs. But I think my crimping is inconsistent, stuffed up some of the necks with the die (Lee loader) so will get a proper set of dies with factory crimp d. So far the only victim to it was a sick 2yo Jersey bull from 20yds, he needed only one. Had this round with me during sika roar but had really bad luck and limited time so couldn't try it on deer yet. Its a real fun load to shoot, I have to buy some more now. Thanks for the help guys.
