    Thanks Larry. I like the cardboard backer behind the target. Good idea.

    I have not done a pound cast yet. It has a very long throat. I can not seat 175gr SMK out far enough to touch the lands.

    waco, watching your video you got a 3&2 group. I'm wondering if you were not at a node where a small velocity difference(barrel time) it got launched in a different direction. I would say your rifle, bullet, powder combination wants to shoot.

    I put five rounds over the Chrony and the load looks very consistent.

    Just because you have a low ES and SD does not make it an accurate load.

    I am in agreement with aggie. I think you need a very small tweak. How did you last 4"of your barrel look inside?

    Waco I'm glad you used IMR 4831 instead of H 4831. The new H 4831 isn't the same old stuff it use to be. I'm sure Runfiverun and Geargnasher told you that already. I don't think that the two are the same because they look different and are far apart on the burn rate charts, where as something like HP 38 and WW 231 are supposed to be one and same.

    It's true that low ES and SD's don't always give the smallest groups. They do show your powder is burning very well.

    I shoot HV and quite a few rifles and one I recently posted to Gunfreak about was the 1909 Argentine 7.65. My bores are just powder carboned to look at them.

    Talking to Runfiverun and getting the scoop on your horrible throat in that rifle you done more then very good, your rifle was amazing. That flyer you had was from the sloppy long throat and nothing else.

    Thanks Vince. I’ll load more and see if I get similar results. I will tweek the load as nessesary.
    The 30xcb bullets were donated by Lamar. My mold will be here Thursday.
    I only had 20 rounds loaded. 5 went over the Chrony and 5 on paper. I wasted a few with scope adjustments so that only left a few to send out to 500.

    I don’t have very many of Lamar’s bullets left. I’ll have to cast some and age them. Might be a bit but I’ll get back to it ASAP.
    Walter.

    Walt you had some very well cast bullets if Lamar casts them. Learn all you can about casting. We're all the same, we think our bullets are the best, but that's more then often not true. Pick Lamar's brain and mine if you want.

    Great job. I enjoyed watching the bullet trace with, what I assume, is the lube coming off...

    Agree on the background music, the video would be fine without it.

    Thanks. I just got my new NOE 30 XCB 5 cavity mold in the mail today. Getting ready to clean and prep it. I'll be making up a batch of alloy this weekend and get some cast and start aging.

    I still have a handful of Lamar's bullets to play with.

    Tomme Boy. The barrel was cleaned 120 cast loads ago. Besides a few kernels of unburnt 4831 it looks good. No leading.

    Okay. So having a low ES and SD, What would you consider an accurate load in a .308 @ 100 yards for a five shot group @ 2260fps?
    I'm sure the load could use a little adjustment. And it will get one. This is the first attempt mind you.

    Nicely done, you took what you learned and applied it with good gear and attention to detail. I'm proud of you and can't wait to see more. I'm on a similar quest but with .32 caliber
