CVA Paramount Update

Bushing is for wear purposes. It's not replaceable in the Arrowhead Gen2 LRMP system, but it never wears out so not an issue.

Bolt head will be slotted like this one. It's going to be a slick system.



Since I don't know if the Paramount has consistent head space, I will handle it same way as I do the UML. Plugs will be made a little long, and can be trimmed to length. If you don't have a lathe, it's not a big deal. I send head space gauges to figured out what length plug needs to be cut. Then you just return plug to me for a quick adjustment. See UML install instructions below. It's easy an works well.



In an effort to expedite process, two plugs are sent labeled A & B. The A plug has been modified to the length typically required, and has a good chance of fitting your barrel without any medication. However, if your barrel is an outlier (and there are plenty of those), the an unmodified plug (B plug) is included as well.



· Remove factory 700 UML plug. Factory plug takes a 5/16” socket.


· Install the A plug into the muzzleloader.

1) Check to see if bolt closes on GO gauge (even a hard close is ok). If yes, go to step to 2. If no, go to step 3


2) Check to see if bolt does NOT close with NO gauge. If no or a hard close, you are done. Please return B plug and gauges using supplied return label. If yes, go to step 4.


3) A plug head spacing: starting with 220 gauge, start inserting gauges until the bolt close. Record the information below and return plugs and modules for adjustment.



4) B plug head spacing. Remove A plug from barrel (it is too short). Install B plug. Starting with 220 gauge, start inserting gauges until the bolt close. Record the information below and return plugs and modules for adjustment.

Ok that is super simple. Piece of cake.

Since it is rear sealing, are you trimming the hex head, or the shoulder for headspace?

Oh, and what case head size are you going to use?

Thanks. Now if CVA would only drop these barreled actions into a Bergara B-14 Ridge Stock for $750, they would get a lot more bites!

Very nice Luke

Thanks Doug

Just curious if anyone has tried the Powerbelt ELR .45 bullets in any other .45 muzzleloading rifles and how they have worked?

Another range day with ups and downs. The good... Last range day I zeroed my scope at 100 and felt pretty good about it. Today, I shot a cold clean bore shot about 4" high at 100, then second shot with a fouled bore pretty much wiped out the 1/2" dot I was aiming at. So, i'm happy about repeat-ability over time and how fast it returned to the last zero after a good cleaning session etc. I know when I go hunting, to foul the barrel first thing then sight in for altitude change. Either way...happy. 2 shots, still no leaking after the stiffer spring was installed.

Moved over to the 200 yard range. 4 shots in a horizontal line. (There was a light left to right breeze that may have caused a little of this, the other is likely me. But overall not bad at all for a 200 yard group. This is with 105gr BH209 and the 180 ELR. Longest dimension was a hair over 1.25" CTC. top to bottom spread was 1/2" CTC.

After these 4 shots still no primer modules showed signs of leaking. One happy camper so far. Then I thought, how bout we grab some velocities with the magnetospeed. Worked well, got 2363 on the first shot, and 2335 on the second. Now here comes the kicker. The second shot leaked so bad the primer module was almost entirely black. Sigh. But anyway, it was a good day at the range and I was happy to see that we are getting velocities well over 2300 with a 150gr charge (Volume)

Oh, and I check Youtube regularly to see if there are new reviews for the paramount or the ELR since these have started shipping now. Found this one last night and it had one piece of very valuable info. They shot out passed 700 yards and range verified BC for the ELR at .333. That sounds a lot more realistic and is more in line with what you see from other low drag 45 cal (Parkers and Pittmans) vs the CVA .452 claim. Here is a link to the video for anyone interested -

Nice report Brad, Thanks

If anyone is still looking for a Paramount at a good price, I ran into a couple today for $822 and $828. Looks like several places have them in stock now, with prices from $822 to over $1100, with the majority in the high $800's and low $900's.

I might talk myself into one of these yet, if CVA doesn't put the fast twist .45 barrel on the Accura MR. If they would drop the barreled action in a Bergara B-14 Ridge Stock for $750ish, I might bite.

I would like to hear more about the 209 breech plug, and how it is working for you guys. Especially with the new spring. Maybe someone would like to try an o-ring? That should clean things right up!

I ran into that video that Brad posted above, yesterday. You can see their primer adapters are pretty dirty. We all knew that the original BC of .452 for the ELR was wishful thinking, and .333 is a much more realistic number.

Thanks for the new info, Brad.

I think I remember reading that Toby shot them in one of his other rifles. Cooper has a new fast twist .45 caliber rifle he is shooting now too. IIRC it has a 1:20 twist Wilson barrel on it. Haven't checked back in there in about 3 weeks or so. He might have posted more information on it since I last checked?

Oh, I also ran into one on Gun Broker today that had a brownish tan stock on it instead of the green for $899. Someone must have swapped the original green stock with a Bergara B-14 HMR stock, because they are the same thing. They would just need to swap over the box magazine and floor plate that holds the Variflame adapters and the capping / decapping tool.

Something a little unique!

I am using the 209 primers full time now. They still leak, but not even close to as bad as the variflame. I also ran into a problem with powder as I ran out of 777 and got a new bottle from a different store and different lot #. It was so inaccurate I was missing the target at 50 yards. I decided to go to the same store I originally got my powder from and found the same lot # powder I was originally using and that cured it. I will try the o ring next weekend. I wasnt trying to introduce anything new while having issues. Here is a pic of my last three shots after getting it dialed in again. 100 grains 777 by volume and a hornady SST 200 grain sabot. This is all at 100 yards.

So easy to change the stock color. Slide one of those babies over the stock (It will cling tight) stuff some pine needles in there for good measure. Choose color you like, go to town... Clear coat after with a satin finish clear.

Turns out something like this.

Luke, are you getting closer to having a production design? I will likely be one of your first buyers on this. I'm tired of cleaning soot off the bottom of my scope turret.

Getting close. Hopefully ready in a week and a half.
