| I want a Marlin 45/70 for hog hunting in the swamp. I came across a 22" barrel 45/70 new for $425 locally but I am leaning towards a guide gun, 18.5" barrel. So I call around and found one ported for $500 and one nonported for $500. So how much you gain speed wise from 18.5 to a 22 barrel . Is there a disadvantage to a ported gun besides noise? Do you lose some speed and does the recoil is reduce enough to be worth having a ported barrel? I plan on shooting 300gr factory rounds in the beginning then getting the dies to reload after the hunting season. Time is getting short so I have to make up my mind this weekend. |

I have all three. I like the 22" due to the Pistol Grip Stock the curved lever is much easier on your fingers under heavy recoil. The velocity diff between the 18.5" ported and non ported seems to run about 80 fps in my guns. Figure about 30 fps per inch of barrel length diff between the 18" and 22" guns. If you are going to use the gun in the swamps, I would use the GG. I dont really have a preferance for the ported vs non ported (either is fine), I use a 400 Gr. Cast and keep it down around 1600 fps so recoil is strong but easily manageable but the muzzle jump is less with the ported gun. The ported gun is an earlier gun, it will be drilled and tapped for a side mounted aperature, the newer guns are not and you must use a top mount aperature with them if you choose to use an aperature. The older 22" guns had micro groove rifling they don't do as well with lead, the newer 22" guns have Ballard rifling make sure you get the newer gun if you choose the 22" gun. |
