I have read that suggested charges for .45 cal 275gr accumax is somewhere between 65gr and 70gr of H4149. What I can’t tell is if this is for a barrel nut gun or one of hanks builds without the barrel nut.
I recently purchased a remage barrel for a build and I am wanting to stay safe so I have a couple questions:
1)is the recommendation of 65-70gr with 275gr accumax for a barrel nut barrel? If no, what is suggested powder charge?
2)what is the charge recommendation for 300gr projectile? If I missed this data I apologize, I tried scouring the thread and I’m sure I simply missed it.
3)I am considering having a suppressor built for this build. Has anyone done so and if I’m shooting the recommended load will this push over pressure threshold? I am trying to be conscientious of my neighbors.

I will address only #3. I’m using a suppressor on my lightweight, but robust, 40 cal. The suppressor works (Hybrid 46). I got an optional MB attachment that replaces the endcap.
When the muzzlebrake endcap is on, I think that the suppressor becomes a long MB with little suppresson. It does reduce recoil much like a conventional MB. It may quieten the noise some, but not a lot. When the rifle is shot, the suppressor/MB endcap doesn’t cause the suppressor to get hot, just warm. When the regular endcap is on, the noise is significantly reduced, the suppressor gets hot (I remove it for cooling, reloading and to blow the smoke out of the barrel and suppressor). I doubt that I’ll ever use the MB attachment again. It just opens up the end of the suppressor.
The suppressor vs conventional MB. Much quieter. Really lengthens the barrel and affects the balance of this light rifle. Recoil is much more noticeable with the suppressor. Shoot your rifle without the MB and see if that’s ok before getting one. I think the recoil may even be higher with the suppressor than just a barrel w/o a brake.
Summary. I love the suppressor for it’s sound suppression (50% +/- - just a guess). The negatives of weight/balance, wait time, cost, reloading, recoil increase (over MB), length, need for cooling between shots, IN MY NOISE SENSITIVE WOODS BEHIND MY HOUSE, do not outweigh the positive effect of noise reduction.
I have another suppressor that fits onto quick attachments on my 300BO(subsonic and virtually silent), 22 semiauto mag 17HMR.
A suppressor on a supersonic bullet is just that, a suppressor. On a subsonic, it’s virtually a silencer.

My Remington build shoots so well the way it is... It makes me hesitant to tear it down for threading the barrel. If it shoots worse afterwards I will not be pleased. Do you think it would be worth tearing it down to be threaded? |

Does your Remington build have a MB? If so, are the threads such that you can get a quick detach that will fit? If not, and it has a MB, a machine shop should be able to make an adapter to screw on the end of the barrel and the MB on the other end.
The recoil will increase with the suppressor if its replacing a MB. I found little noticable suppression with the MB attachment on my suppressor. If I didn’t have a need for the suppressor (noise sensitive area) , I wouldn’t likely use it.

I never wanted a brake on my gun so it was built without threading the muzzle. My concern is that having a 1/4 MOA rifle torn down, threaded and put back together will it still shoot 1/4 MOA? I don't specifically mean 1/4 MOA with the suppressor, I'll shoot it without if the groups are not good. I just don't want to ruin the accuracy of the best shooting rifle I own. |

My ultralight rifle is ultralight. Comparatively short, small, extremely well balanced, easy to load thru the aluminum, small MB.
The 460 Hybrid is 7.6” long, weighs 14 oz plus the barrel attachment (a few oz’s). That’s long and comparatively heavy. With it’s MB accessory, it largely looses suppression. With the std end cap, the recoil is greater than without the suppressor. It is easy to detach for reloading, no problem.
For me, it is worth the hassle for the needed quietness where I hunt. But, if I didn’t need the noise suppression, I wouldn’t use it on my ultralight rifle. For my robust, all out , heavy 40, I would; but, it will be for sale since the ultralight is all the 40 I need. When a rifle is already heavy another # is minor. On the end of my ultralight, it’s a different story.
I don’t think threading the end of the barrel would ruin accuracy. You would have an endcap.

Do you think it would be worth tearing it down to be threaded? I’m in the same boat as you with waiting on the ATF (10 months in jail) and deciding what to do on my break action that’s already thread for a muzzle break. My barrel is already cut down to 17” and is extremely accurate just the way it is. Unfortunately, I would have to cut the threads off and rethread it to fit the new QD muzzle break for my suppressor. I’m going to pick up another CVA and cut it down to 17” for the new setup. I think with the barrel cut down to 17” and then adding a suppressor it will balance out the rifle very well. Then I’ll have one with and without for a side by side comparison. I’ll end up selling one of them after my testing is completed. |

The recomended load for the Remington Pre-fit barrel is 65 grains of 4198 with a 265-275 grain bullet. If you are going to shoot a 300 grain bullet you need to drop that charge down to 60 grains in my opinion. |

Buckeye & others,
My only negatives concerning a suppressor on a MLer have to do with barrel length/balance and weight. My ultralight was designed to be the ultimate, fo me at least, walk around, easy to carry, yet, medium range rifle. It was perfect for that! With the MB, 24’ barrel went to 32”, it became nose heavy. It is much quieter and has more recoil, though not bad at all.
With a short barreled rifle, especially a break open, I think having a suppressor is a no brainer. If I were much younger, had plenty of $$$$$ to spend, I’d have 2 of my ultralights: the one I have with it’s MB and a 18-20” barreled one with a suppressor.
As barrel length shortens, and if strength isn’t a limiting factor, just using a faster powder can keep speed up and fouling down.

I was hoping to get my suppressor back before season starts but that isn’t going to happen. Maybe in time for Ohio late muzzlerloader season in January? I’ll post some pictures of it as soon as I get it done.
