CVA MR-X 50 cal questions

[Haburchak.257]

Hey everyone, I’m pretty new to the muzzleloading world and trying to get into it in more depth. I have a CVA MR-X 50 cal and I’ve been shooting 250 gr powerbelt elr bullets and hogdons triple 7 pellets. I’ve had pretty good luck but I’m really wondering if there’s something to taking a fowling shot before ever going out to hunt. My groups all seem to be like the picture below. The first shot is right on and then shots 2-4 or 2-5 will group well but never close to shot #1. Any advice for a newbie? Thanks!

I am also new to muzzy and interested to hear from the experienced muzzy guys.

Are you cleaning at all between shots? Spit patch or anything?

I’m cleaning every 4-5 shots. I may try to clean after every shot at my next range session and see how the results differ

I swab between shots at the range but every so often shoot two in a row to simulate a follow-up shot. Swabbing consists of running both sides of a windex patch down the barrel, followed by both sides of a dry patch. I never shoot with a clean barrel and before I shoot at the range or hunt, I foul the barrel with 3-4 primers.

Thanks for the info, this is probably a dumb question but what is the benefit of fouling the barrel with the 3-4 primers instead of a completely cleaned barrel?

Are the shots 2-4 or whatever always in that same spot, or does that group move around?

They have some variability but all in the ballpark of the photo i included. They generally still group well even if they shift.

It serves two purposes to me:

1) I never have a fully clean barrel at the range except for the very first shot. I am basing all my groups and accuracy on shots with a dirty barrel so it makes sense to have some fouling in the barrel for hunting.

2) It clears the barrel of any excess moisture or oil before loading a shot that will hopefully be heading towards an animal. I want to mitigate any risk of a misfire, and the only misfire I've ever had was because the barrel was a little damp and the powder "bricked" together, for lack of a better term.

Primers are non-corrosive, so there are only benefits to fouling with primers to me.

Well that makes sense to me, i will have to try that next time i shoot. Thanks!

I have a CVA accura MRX 50 cal. I always hunt with a fouled barrel.

I shoot BH209 and fury universal fit 320gr bullets. I typically shoot 10-15 rounds before cleaning unless the gun is going to be put away for any significant length of time.

My preferred routine for hunting is: I start with a clean barrel. I go to the range and shoot 2-3 fouler shots. That is where I hunt with it. I do not see a noticeable change in accuracy from shots 2-15. I do notice that loading can get a bit tougher after ~12 shots.

If I am in a bind for time and cant get to the range. I will stop somewhere on the way to my hunt and fire off at least 1 round to foul the barrel.

My particular rifle would probably be okay to hunt with on a clean barrel. I do not see a significant change in POI from my clean shot to my fouled shot. But I have had other rifles that the clean shot POI can vary drastically. For this reason I opt to always hunt with a fouled barrel.

That’s good info, thanks. Have you ever shot pelletized powder or always the Blackhorn 209?

 

[RaggedHunter]

Also worth adding that if your rifles POI shifts between your clean shot and your fouled shots. That you will want to sight your rifle in on a fouled barrel as well.

I have not ever messed with pelletized powder. I have only used BH209 and other black powder substitutes. But I believe the idea of hunting on a fouled barrel holds true regardless of the powder.

I use the same philosophy with my centerfire rifles as well. I never hunt with a clean barrel.

My older CVA MR holds good groups on a clean barrel, so I clean between every shot.

But I have also verified that a follow up fouled shot is still precise enough. If it wasn't I would hunt and shoot it fouled.
