Henry Big boy / Marlin interchangable springs?

[aboriqua]

I have a Henry Big Boy in 38/357. Beautiful and smooth but I cant get through a tube of reloads without light striking.

I have used the same reloads in revolvers for at least the last 5 years and thousands of rounds. I was able to light off about 120 rounds of Factory Remington 158 gr HTP SP's.

I am using CCI primers and was sure not to arm wrestle the press when I installed them because I was afraid I was pressing the primers in to deep before when using winchesters.

I want to try a heavier hammer spring. I thought I read that the marlin 1894 and the Henry share a very similar internal design.

Does anyone know if the hammer spring for the 1894 1895 marlin will work in the henry?

I was looking to try the extra power

Thank you for any help!!

Just call henry, there's no doubt they'll take care of it.
Primers need to be fully seated, do those rounds fire on a second strike?

Its already been back to henry once so I was kind of resistnat to sending it in again. Soon after I got the rifle and in under 50 rounds the extractor just broke out of the bolt. My wife saw a small pile of parts on the bench and the bolt had been cracked where the extractor pulled out. It came back home with a few marks that werent there when I sent it so I figured I might try and work it out myself.

I also dont know how to approuch Henry since most manufacturers will tell you they dont want you using reloads anyway.

About half of the rounds fired on the second strike. The rest cycled through again.

When I used the reloads that had been using in the revolvers I was really pressing the primers in with some force. I took a caliper to the primers of those older reloads and found out they were seated deeper than recommended. I was so nuts to make sure there was nothing wrong with the rifle I went about changing the way I had been reloading and this time FIRMLY sat the primers but didnt use gorilla power. I then took a bunch and measured just to be sure. All within spec.

Now .. I am about to say something potentially stupid but .. sometimes when I have done work to one of my revolvers I will put a pencil with eraser in the gun and drop the hammer. After all these years I know what a proper launch looks like. When I tried it with the Henry .. the pencil wont clear the 16" barrel. I know its a two part firing system so maybe that is the reason??

Try shimming the spring. I did that on a Marlin I had lightened too much. Fixed it right up.

I'm a cowboy action shooter. Many of us have lightened springs in our guns. Federal primers are "soft" and will give reliable ignition. CCI primers are high quality but they are just about the hardest. Winchester primers are somewhere in the middle.

I remember when my Match Director let me borrow a rifle that he had just gotten back from a cowboy gunsmith. I was using up my stock of CCI primers at the time. I loaded ten rounds in that rifle and it wouldn't fire any of them. Tried again with ammo with Federal primers and it ran fine. There really is a difference in primers.
