rifle H&R 38-55 Winchester model 1871
 
Hi, I bought a rifle H&R 38-55 Winchester model 1871 2 or 3 years ago. I used it with 0.375” sized bullets from different manufacturers (Sierra, Speer, Hornady, etc.) Each shot would hit the target as key hole. I called H&R customer support told me that the bullets were too light.

I searched on the internet for solutions, and I found that other people had the same issue with this rifle. The problem seems to be that the rifle’s groove has a size of 0.379”. So, I have to use 0.379”, 0.380” or 0.381” to get better and accurate shots.

Recently, I bought a mould from the Lee company with a size of 0.382”. I converted old bullets with a 0.381” size. Also, I bought GasCheck bullets with a size of 0.380” (266 gr LFNGC from Cast Performance Bullet Company ) but I cannot use them because the chamber is too small for them to fit in.

Do I have to make the chamber larger so I can use larger bullets with this rifle?

I will list the bullets and rifle stats:
- Bullet Size 0.375”x2.760”, the rifle will close correctly. Neck size 0.3925”
- Bullet Size 0.3775”, the rifle will close correctly. Neck size 0.3935”
- Bullet Size 0.379”x2.4375”, the rifle doesn’t close correctly. Neck size 0.3985”
- Bullet Size 0.380”x2.4325”, the rifle doesn’t close correctly. Neck size 0.3995”
- Bullet Size 0.381”x2.4335”, the rifle doesn’t close correctly. Neck size 0.4005”

I am not able to use this rifle with bullets larger than 0.3775” which is really annoying. I happen to have many H&R and N&F rifles, and only this one seems to give me troubles.

Sincerely yours,

Jean-Mario Charest

Welcome here. :cool:

Unfortunately, I can't help you, but someone should be along who can.

You should be using a .375" rifle bullet.

If you are casting bullets then you need to size them to .3755 or .376".

You can not shoot bullets that are larger than the gun calls for. So why are you trying to use .380" bullet? .005" doesn't sound like much but that is a rather large discrepancy in the shooting world.

Making the chamber larger is not going to help you do anything but blow your face off.

I am the newest member of the forum and have no intenton of stepping on any toes, however, please be advised that most H&R 1871 Target Classic rifles have the same problem as most Marlin 336CB Cowboy rifles chambered in 38-55 Winchester: the chambers are too small for the bore size. The chambers are cut to fire the 255 gr. JSP Winchester factory ammunition which has a bullet diameter of .377", but the bores slug at .380" to .382". In order to expect any kind of accuracy, a minimum of two things must be done:
1. The chamber must be opened-up .005" to .006".
2. Cast bullets of .380" to .383", depending on actual bore size, must be used.

Go to this web site for a very good article about how to get the H&R 1873 Target Classic 38-55 rifle to shoot. Brimstone Pistoleros Official Site .

I get my 38-55 hard cast gas checked bullets from beartoothbullets.com and castperformance.com .

Jean Mario,
I hope you have solved your problems with getting the proper size bullets to shoot from your H&R Target Model 38-55. It is the same problem I had using W-W cases and .380 Cast Performance Bullets. The .378s would chamber but not .380.
Simply order some Starline Brass in 38-55, it is thinner and works fine. The W-W is 375 Brass with a 38-55 headstamp is all and is too thick. You can get Starline in the correct 38-55 length of 1.125" or in the 375 length of 2.080, either will work.
The chambers of the H&R are cut too tight to take a bore sized bullet and use the thicker brass without turning the case thinner.
Good luck, yours has been a very common problem and required opening the throat with a reamer before Starline started offering their correct sized brass cases.
