    I think Bellum Arcus has stock. I do recall they were silly expensive though. Something like R900 for 50 rounds or something.

    Some feedback.

    Took Hodgdons load data for a 190gr Hornady bullet and loaded 12.3 grains of CFE BLK Powder behind a 188gr Peregrine bullet loaded to a COL of 52,07mm. Load data is for a 16inch barrel, my rifle is an 8.5inch

    The rounds feed and eject when run through manually.
    They feed and eject when only running the muzzle brake
    They FTF when running the suppressor

    The rounds when fired with the suppressor on were freakishly quiet, and considering it was an indoor range, the extent of the noise was the round slapping the paper packed box and the action

    I got Jean from Kalahari to run the figures through Gordons reloading tool and the suggestion is a COL of 55mm (2.165") and a charge 14.6gr. I will give that a try, will just confirm that the rounds will fit in the mags at 55mm, and revert

    Just a suggestion.

    Only tweak 1 variable at a time.
    What i do find odd is that it will feed without a suppressor but with it doesn't... usually it's the other way around with subs as the can increases bolt speed.

    If a Roll sizer is set up for .223/5.56mm will it be able to handle .300 AAC blackout, or is there a calibre specific part needed?

    Common sense tells me it should be able to as the base of the case is the area in question and neck sizing will still be necessary? No personal experience with roll sizers yet.

    Why do you think you need a roll sizer for a rifle cartridge?

    The bulge at the bottom of the case, does it only apply to pistol calibres?

    Rifle chambers normally support cases well enough that you don't get bulges. Not sure about semi-autos though.

    Ya, I hear what you are saying, I am not sure I am going to have a compressed load at the current length with the higher charge.
    Will test higher charge and then higher charge with longer COL and let you know
