    16.25" vs. 20" barrel in 30-30

    Looking at picking up a truck gun and trying to decide between the 336 in 16.25" and the standard 20" or maybe even a BL 18". How most velocity would one might expect using the lever revs. I like the idea of the little 34" gun as a truck gun and will likely have my kids harvest their first caribou with this rifle so compact setup would be nice as well.

    I have a 1895 SDT so I am kinda a sucker for the 16" barrels, but if there is a significant velocity loss with 4" less of barrel I may have to reconsider.

    Thanks for any input.

    Re: 16.25" vs. 20" barrel in 30-30

    There is a LOT of info here about the real and/or perceived velocity losses of shorter bbls. Bottom line tends to be, it depends. But generally accepted rule of thumb is ~50fps/in. But again, it depends.

    I don't know that I see any real advantage to a short barreled rifle for what you describe, especially if you're hunting on the tundra. The short barrels really shine in snap shooting in thick timber, etc.

    I go into some deep dark spots with my 20" barrels and have no issues.

    Alaska - Do you reload, or know anyone that reloads? Some velocity loss can be off set by using powders such as IMR 4198, or Re7. Either way I would think a carbine with a 16.25 barrel would still prove to be enough gun for your purpose. Shenandoah

    Re: 16.25" vs. 20" barrel in 30-30

    Thanks guys. If just shooting leverrevs in each marlin (16, 18, and 20) 30-30 marlin I could expect about a 100 fps difference between each rifle roughly?? So if a 24" barrel shoots them at 2400 FPS at the muzzle a 20" barrel would have 2200 FPS at the muzzle, 2100 fps in the 18", and 2000 fps in the little 16"....roughly??

    Re: 16.25" vs. 20" barrel in 30-30

    I have all four barrel lengths. The shortest barrel is the best for the truck. I would not lose any sleep over velocity. All four shoot well and have plenty of power for most needs. I have taken game with them all. If the velocity matters, I have not noticed it.

    Re: 16.25" vs. 20" barrel in 30-30

    I have two 30-30s in 20 & 24 and 444s in 22 & 24 and, in my limited experience, have found that my longer barrels shoot a little tighter and prefer around grain more powder in my hand loads. Plus given the believe that longer barrels give more velocity, I do believe there is an advantage to longer barrels that more than offsets the slightly shorter barrel advantage
    Look at a wolf, look at a deer, look at a human, look at a black bear. The 30-30 was designed to be the most efficient caliber to down any of them within the range you would most commonly encounter such creatures.

    Always thought the 20" modle provides ideal balance of balance and portabilty

    A few years ago, I chrono'd 35Rem Lever Evolution ammo in my 16.25" 336/35 @ 2144 FPS...........That surprised me, but the MUZZLE BLAST surprised me a lot more! ...................I'd rather shoot my Hand Loads.......They're load, but not so load, it sounds like the world is coming apart!

    That too, it just carries right. I put a 9 round ammo carrier on the 336XLR to balance out the heavier barrel. Makes the whole thing a little heavier, but it feels alot better. If I had one of those shortie barrel rifles I would probubly have to change out the stock to something lighter. That's just my preference.
