Aside from that, I think the accuracy problems with this rifle are going do be obvious by design, but with my previous handloads I have found that the ammunition available for his rifle probably make up 50% of it's accuracy short comings. A good handload can make up for half of its problems. At least, this is what I have learned so far with my rifle.
This is why I found interest in this thread. Measuring the chamber and throat space will be very helpful when selecting bullets... Jacketed or Cast.
Where I live, a 100yrd shot is rare. But a good handload will make the difference between 3in group and 6in group. Factory steel cased ammo is plenty good for 75 and less, which is probably about 90% of the shooting that is likely to happen.
