Of the top of my head the lurch field holds 17rounds

The Evans repeater holds 20 something. 26 maybe?

You can find the ammo capacity in the infobox for each weapon’s page. The Evans holds 26 rounds, meaning that it would be the gun to store the most ammo. Repeaters generally hold more rounds than rifles.

Evens but even is weak

Also just so you’re aware, your weapon automatically reloads when you enter deadeye so ammo capacity isnt a very big deal unless youre looking to play specifically without deadeye

Evans, 26 rounds, personal favourite, it's just a bit weak and suuuuuuuper slow reload

Thanks for info everybody.

(spoilers)

In case anyone is wondering I wanted to know this in order to prepare for the mission where the O Driscolls attack your camp. I remember last time I played there were so many of them f*ckers I couldnt keep up with killing them all because I only had the bolt action rifle and two Schofields and I hate them so much and I want to make sure I kill all of them this time.

@Justinclae ive been using that trick since Red Dead Revolver ?
