I have an 1894 Marlin 38 357 with a Marbles standard rear tang sight. It shoots 38s with 158 RNFP with 3.5 of unique 6.5 inches high at 25 yards. 357s with a 158 JHP and 6.6 of green Dot 3.5 high at 25 yards. The rear sight is as low as it can go. Any ideas how tall a front sight I need to get?
Thanks

A call to Marbles and let them know what rear sight height you have and I would think that they could tell you what front height you might meed.

Hey there 161 -- Welcome to Marlin Owners. You've got a great combination there. Get ahold of a Skinner front blade sight (see the industry partners section). Pick the ammunition you will be predominately shooting and start sighting in your rifle. I like to put zero to two clicks in my rear sight and file the front sight off until I have it shooting right on at 50 yards. From there on it is just counting and recording the number of clicks for targets farther away. Keeping a cheat sheet of sight settings for each particular rifle is handy, especially if you get to shooting games like silhouette. Here is a target showing the elevation as the front sight was reduced to give you an idea. I wasn't too concerned with windage adjustment until I was close to the correct elevation...Hope this helps. Best regards. Wind

I called Brownell's and they gave me a formula that I thought I'd pass on. I'll bet some of you already know it but I thought it might be helpful.
Take the length of your sight radius in inches times the number of inches correction you need then divide by the distance your were shooting in inches.

My gun has a 24 inch sight radius
shooting 6.5 inches high
at 25 yards
24X6.5=156
25 yards =900 inches
156 divided by 900=0.1733333
So you need to change the height of you front sight .173 or as close as you can. Hope somebody find this helpful.

I am assuming that if you have a 24" sight radius, your barrel lenght is 20"??

16 inch barrel. But I installed a rear Marbles tang sight. That's how I got a 24 inch sight radius.
