The three bullets I have narrowed down to I really want to shoot are the Barnes tmz 290 grains the thors and Hornady fpbs in the 300 grains out of those which would you guys shoot. I decided on the gun a cva accura v2 long range. You can find a lot more bullet options around when in the stores and the 50 is a do it all gun.
Thats called a Bore Cot. Its basically a rubber balloon that slips over your muzzle to keep the foul weather out. I find that they change the bullets point of impact greatly at 150 and 200 yards. 75-100 isnt much change, but it shows. Notice how the 2 shots when I used them, impacted to the right and the shots to the left were without the bore cots.
As for bullet failures, I've yet to see an actual person on a forum use them on a hunt and report back.
They basically are a barnes. They are 100% copper and are in fact a good deal thinner where the petals peel back.
I've only shot 2 packages of them with a variety of powders, so I can not add a whole lot to how they perform at longer ranges or on animals.
