Hello to all.

First off I just want to say that all the people on this forum have been extremely helpful in my past posts. This is a great site. Hopefully all can help with this question. I have a Marlin Mod 97(1897)in .22 s,l,lr. I have heard that the bolts on some of these rifles were a bit weak and would crack when used with high velocity ammo. Mine has a serial number if A73**. I wondered if this is within the range of weak bolts or even if there is a range of them? Thanks for all the help.

    I have shot high velocity .22LR through my '97. It should handle standard velocity LR rounds, but these days, I feed it .22 shorts. I have other .22's for pushing the envelope of the .22

    I've got a bit of a followup question (thread hijack).

    Suppose you have an older model 97 and want to swap out the bolt for a more modern one that can handle high pressure ammo.

    Will any bolt just drop right in, or do you have to have this fitted?

    Will Marlin do this conversion for you?

    Thanks.

    I paste and cut the information below for you and you can see you should shoot sub-sonic, the bolt to handle high speed ammo was not installed until 1932. If you look at the pictures of the bolts of 97 and 39 were the same in lieu of small changes in parts. I have a Model 39 without prefix and I installed a modern Model 39 bolt, extractor and firing pin. Some of these bolts will drop right inn and headspace, the bolt I got I had to stone to fit the receiver before head spacing.

    Breech blocks were still made in the configuration as previously & were weak enough that breakage could occur if using Hi Speed ammo. These were identified by either no prefix to the serial number or a prefix of "S". In 1932 the machining was changed & it was then acceptable for & recommended to be used with Hi Speed ammo, the serial number prefix of HS was then added.
