My marlin guide gun is giving me a problem.
The gun is for hunting. Also target shooting, banging away at gongs for fun.
I figured reloading would allow me to do both.

I equipped the guide gun with a Williams peep sight and a fiber optic sight.
I bought 100 new rem brass.

Load 1) 405 grain hard cast and moly lubed RNFP and 12.0 grains of trail boss
1 1/8 groups at 50 yards. averaging 920 FPS.

Load 2) 350 grains hornady FN jacketed bullet. 48.2 grains of Reloader 7.
3/4" group at 50 yards. averaging 1800 FPS

The problem is the slower loads print 11" higher than the fast loads. This is I was told is due to the slow loads are more effected by muzzle flip.
This will require me to borrow a press and change sights up front when I swap loads.:(

what to do???
 
Or you could run the 405gr bullets faster, the recoil on those loads at 1250 is minimal anyway. I think it will still be high but not nearly as bad

I think you are going to find short light guns are going to be recoil sensitive. Heavier bullets with more recoil are going to kick the muzzle up higher by the time the bullet leaves the barrel. I had a TC Contender rifle in 30-30 that shot about 12" higher at 100 yds with 180 gr slugs compared to 150 gr ones.

Yeap, I find the Marlin GG has the muzzle rise up when shooting heavy bullets.
I shoot a 405 RN hard cast with 50 gr of IMR 3031. I tried some of my sharpes loads 600 gr bullet, WOW, reminded me of my 416 Rigby...

Those loads are DRASTICALLY different in pressure, barrel time, bullet weight, burn rate, etc. No surprise that they're that far apart on paper.

I have one rifle that will put 2 different brands of bullets, same weight, over the same powder charge, 16" wide and 10" high of one another.


I'd try a plinking load with Trail Boss under a lighter 350gr bullet first.
 
.45-70

Yes, indeed the .45-70 is a caliber that shows drastic changes in POI with different loads and/or different bullet weights.

Sight in carefully at 100yds for your no 1 load (best or most often used).

Then for the other loads make careful notes about POI changes and record it for further changes.

No other way out...........

OR


You may decide to scope it for target or whatever you want to do with one load and irons for the other load as well.

Removing scope is easy and there you go.

OR


I use the 1895 for hunting and an 1885 for target shooting ;)

Sounds typical I found even with the same bullet weight a slight change in powder charge makes a difference. Pick your two loads and mark or just remember the elevation settings on your rear site works and is what I did to use cast and jacketed loads.
 
lead vs cast and the ballard rifleing

Can any experienced 45 70 hand loaders offer any options re lead vs cast and the Ballard rifleing of my guide gun.

Might the group be tighter with a 405 grain GS lead bullet for hunting?
