    I had a chance to put 3 rounds through this a few weeks ago. I did not have a chronograph and it was only 3 rounds as I was not expecting to have an opportunity to shoot it given the location.

    The loads were a combination of 410gr projectiles I purchased from ShooterNZ here on the forum and 450gr projectiles that I am making myself.

    The load for both was 15-16gr of ADI AP100 with about 0.8gr Dacron filler. I have been learning all about case mouth flaring and expander mandrels, as to this point all my loading has been for boat tail jacketed projectiles, so a bit of a learning curve to deal with cast bullets well. Quickload estimates this load to be right on 1000fps.

    Recoil was stout but not obnoxious. I would liken it to my lightweight and short 308 hunting rifle shooting hot loads. With full house 45-70 rounds I think it would be extremely unpleasant to un-shootable. It is only 3kg after all.

    To my surprise, my efforts seemed to pay off in drawing the projectile path and barrel/barrel block in CAD to work out exactly how high my front sight and rear sight needed to be. It was shooting approx 2.5" high at 25m and good windage, which is close to what it should be to give a zero of about 80m and then around 3.5" - 4" drop at 100m.

    I have been playing around with making a mold for casting my own 450gr projectiles. It took a few goes to get one that would fill out and eject the bullet properly. It is not a split mold and is along the lines of paper patch bullet molds since it does not need lube grooves as I am powder coating. I need to remake the sprue plate and make a decent handle for it, but I managed to cast enough for testing.

    I have 20rds loaded up ready for some proper testing once I find somewhere to shoot. I lost access to my last spot about 6 months ago as the property was sold

    I had an opportunity to shoot this properly today. Unfortunately, only at 100m, which is not ideal for a rifle like this, with sights like this and eyes like mine. Saying that, I shot at a 10" gong for the first round and smacked it good, much to my surprise. I then moved to paper and shot 4 rounds of my 450gr projectiles and got a "group" of around 5moa, which I am very happy with. I could only barely make out the target ring as the sun was heading down and directly on the target. The sights seem to be pretty close at 100m, more than good enough for a rifle like this, which I don't intend to shoot further than 80m or so. Velocity averaged around 1060fps, so I might drop 0.2gr to keep it consistently subsonic.

    Load was;
    Hornady brass trimmed to around 1mm shorter than standard
    Custom 450gr projectile, powder coated and sized to 0.463
    14.5gr AP100
    1.0gr Dacron Fill
    Random primers from the bottom of my reloading drawers.

    The next stage for this rifle is to make a suppressor for it. I can go to around 40-41mm before it starts getting in the way of the sight picture and I will keep it fairly short at 160mm or so, it will likely be aluminium tube and baffles and I will probably glue it together rather than threading to keep the weight and complexity to a minimum. The goal of this is not to have a mouse fart gun, but something that can be shot without hearing protection and not have the far-reaching sonic crack of high velocity cartridges so it can be used in less than rural areas when less noise is needed.

    I am moving my house and workshop over the next couple of weeks, so nothing will be done for a while.

    Same with me, my last "bush" shot opportunity was 310m. Luckily I was carrying a mates 6.5CM with a range finder and drop indicator built into the scope. About the easiest possible way to shoot 300m.

    I haven't had an opportunity to shoot this again between moving house, organizing my workshop and now the cops are dragging the chain on my renewal and I have no license or firearms at the moment. I applied over 7 months ago.

    Im pretty sure if you made up some more wee apertures that fit onto dovetails...both sizes and could keep the cost down,they would be rather popular and sell like hot cakes...

    Greeting @Micky Duck.
    A lot of continental rifles have a 12mm approx dovetail including some of the early Brno .22 rifles. I have heard of some making up an adaptor to take an aperture sight intended for 3/8" dovetails.

    The problem is in keeping the cost down. Aperture sights (even very simple ones) are fiddly things to make. I would have to charge in the region of $150 for them to be worth my time, and even then I would not be making much, if anything. Unfortunately that's just the reality of manual machines and small scale.

    For Baikal's in particular, you would need much higher than standard front sights as well if the aperture was sitting on top of the dovetail.

    Its a good idea, and there are bound to be people interested in the product, but probably not for the price tag that would be necessary.

    Why not make a clamp type front sight with a 15>20mm high blade that you can cut down to suit as there a lots of old peep sites floating around that could be fitted by the average bubba .

    If you are going to make a clamp on foresight, make it suppressor diameter and give yourself the extra sight radius. I've been thinking about something like that, with a couple of grub screws to keep it in place.

    Make it DPT sized, and open your market right up. That, and a skinner sight attached to the rear base could be a very handy back up set, or full time for bush hunting in the rain.

    I sized the front sight on this rifle to take a suppressor. Limited it to around 38mm though, rather than the standard 44mm to keep the front sight height reasonable when there is no suppressor attached.

    Again, as far as making a product to sell, front sights are even more fiddly and time consuming to make.
