Can not sight in new accura Mr-x (advice needed)

[ElDiablito]

Does anyone else know a rough estimate what my FPS should be with my setup :cva accura Mr-x, 2 IMR white hots (100G), cheddite primer, & 290G Hornady boredrivers?

So I want to update this, as I’m unfortunately still unable to get good (huntable) groups at 100 yards. Yesterday I shot at 50 and it wasn’t great but it was close. I moved by turret up to clicks and moved target back to 100 yards. First shot I completely miss target… hoping it’s a fluke I shoot again and hit 2” high and 2” to the right. Next shot is touching then following shot hit low but still not horrible then my last shot is so low it misses the paper and hits bottom right, almost 12” lower than previous shot…. Wtf… at this point I was going to call or email cva to see what they thought but they’re closed for holidays.. I’m thinking I got an accura lemon (I’ve seen lots of people say this about the Mr-x), or it’s that damn breech plug. Maybe the pellets aren’t sitting flush. Can’t find another one available so does anybody know for certain, that I can use the black horn breech plug with pellets? If not my next step is trying some BH 209. If that don’t work I’ll swap scopes and after all that, it’s getting sold if I can’t get at least 2”-3” groups at 100 (which I would consider bad but I’m new to muzzleloaders so not sure what’s realistic). Again, it’s ok at 50 yards but completely falls apart at 100 yards.

Have you put a reliable scope on there to verify it’s the gun versus your scope shifting all over before you go complaining to CVA? Frankly it sounds like a scope issue with the wandering shots.

Both my CVAs shoot tight at 100yd with open sights.

Your scope is trashed. And it's telling you so every time you go out. It wasn't good to begin with and the lead sled finished it off. In not the first person to tell you that.

You've also been told a bunch of times to just pick one load and stick with it, and to stop cleaning so much.

This thread actually has a bunch of good advice if you'll just read and act on it. I really doubt that your barrel is the problem. Everything else in your setup and approach is extremely suspect.

Call Luke at Arrowhead Rifles @LWH723

Scope or you have a consistent ignition problem/powder issue

Take off a quality scope off one of your guns install it on your muzzy and hit the range and see if that corrects the problem. If you have the gun on paper there is no reason to adjust the scope to get it in the bull. At this point you want to fix a problem. Just shoot a 5 shot group and see if they group. And don’t clean between shots. If the gun still shots bad then you may have a gun problem. And you really need to shoot off a bench with bags or bipod.

This is actually kind of ironic. I had a Wolf with that same scope and it did the same thing. It shot pretty good at 50 yards, step back to 100 and it was all over the place. I was a broke ass newly wed at the time and didnt have funds to try a new scope so I just sold the gun.

If I had to guess, its your scope.

I’ve stuck with white hots & 290G boredrivers. They seemed good at 50 but open way way up at 100. Never had a scope fail but how would I know? It’s not loose at all.. would the reticle had shifted or something internally?

Yes, it could be the reticle or some other internal part that isnt holding in the scope.

Really the only way to know would be to try a different scope on the gun. Preferably one that has been proven reliable in the past.

Nikon quit making rifle scopes.

It wasn't because they were good at it...

 

[dsotm]

Try putting a reliable scope on, yours is probably trashed

I shoot the same combo in my MR-X (2 White Hots pellets + 290 Bore Driver) and my drops tell me I'm getting 1610 fps, which is very close to what's shown on the table @ElDiablito posted.

Awesome, thanks for confirming. What kind of grouping are you getting at 100 yards?

Has anyone tried to use the blackhorn plug with pellets? Still need more powder so I’d like to stick with the white hots but I’ll have to go to BH if I can’t use this breechplug with pellets.

This was last time I shot. That's a 1.5” dot at 100 yards. Using a Holosun 510c red dot (no scopes allowed on muzzleloaders in AK).
