Jeff has been turning quite a few of these into muzzleloaders and they all seem to shoot good. I bought this one to keep as a 45/70. My first impressions are good the SS mat finish is nice and the gun points well and it balanced pretty nice with a decent size scope this gun weighs 9.0lbs . I mounted a 4x14 Bushnell Legend I had laying around since this scope ring combo on the gun only uses one scope tubes the scope base and ring set are very solid.
I bought two boxes of Hornady 325gr ammo that way I had a base line to work from and also would end up with the brass to reload. Well after bore sighting this gun at 25 yards I saw that the scope was almost out of adjustment in elevation not a good thing. You can get some pretty crazy results when mounting different scopes in the same set of rings. I was able to get it on paper at 100 yards but the scope of almost out of adjustment I don't like to shoot a gun that way so I crank the elevation knob down so I new it had enough spring tension on the erector cell . Shooting this gun compared to the 450BM is about the same in recoil even though your shooting 325gr bullets compared to 250gr bullets. The extra weight in the rifle helps tame this cannon down. The accuracy was flat out amazing for factory ammo 3 shots well under 1" without any trouble I also shot it out to 220 yards on are metal swinger and had no trouble hammering that plate.
My next tests will be with Barnes 300gr originals I plan on using H4198 powder since that has always worked the best in the past my target velocity will be around 2400fps which I think is doable. That load will make this a very good performing gun out to 350 yards. |

The Hornadt loaded ammo with the 325ftx is short for lever actions. If you buy new brass, it is the correct length. Also, my favorite bullet in the 4570 is the 300gr barnes ttsx.
That bullet over 50gr of RL7 is deadly and accurate.

This was supposed to go on the Center fire board my mistake. 60grs of H4198 in this case is really compressed with a 300gr bullet. These CVA'S are not throated out very far. Also If you use RCBS dies the seating die is not setup for spritzer bullets it flattens the tips on the 300grBO. I used my 450BM seating die that die is setup for pointed bullets.
Very nice gun for the money.

Just a quick update this gun eat that Bushnell Legend scope today no more side focus. It handled factory loads but when I put some high velocity stuff through her it only took 3 shots to kill the side focus.
I do think break action guns are harder on scopes then when there mounted on top of a center fire action for some reason.

I tested the 300gr Barnes with 58grs up to 59.5grs of H4198 in the shorter Hornady cases. 59.5grs shot the best and gave a velocity of 2450fps not bad. I plan on buying some new brass with the correct length I do have a few old pieces and that extra .070 length makes a difference with the powder charge I do believe you can get a safe 2500fps with this gun that would keep it below 50,000 psi.
Also this barrel does not like to shoot when first cleaned it needs a few shots to settle in then it will group that's better than having to have a clean barrel only shoot good. Next step is another scope to use.
