45-70 vs .444 Marlin vs .454 Casull

Hi guys,
If we compare apples to apples, and we use rifles/carbine in all three cartridges. Which do you think that have better terminal performance at ranges of up to 120 yards on medium animals like deer and wild boar?
Which do you think has better relationship of projectile weight-velocity-diameter-weight the game?
Apparently the .454 Casull is not in the same league, I haven't used it, but I've seen some videos which have impressed me, considering the size of the case.
What do you think??
Come on, cheer up!!

454 has impressive ballistics and you get a lighter kicking / cheap practice with 45 Colt. But the Casull runs at very high pressures. I have heard that the Rossi 92s have a habit of bending action bars if fed a steady diet of 454 Casulls.

45-70 can be a thumper but can be loaded soft. Perhaps the easiest to feed of the 3 and easiest to find.

444 is for me the sweet spot. If you reload you can shoot 44 cal pistol bullets. For “serious” hunting you can use 280gr Woodleigh, 265 Hornady Interlock and FTX plus up to 300gr FTX. Sierra do a 300gr JSP. I think it’s cool. As you can load plinker with cast boolits or up to punchy.

Hi Marcos, I have been monitoring this for some time now. The .452 bullets are very good killers but there are some limitations. If for example one uses a 250gr conventional HP driven very quickly (carbine speeds / .460 / Bushmaster speeds), the bullet may display blow back such as 2 to 3" entry wounds. Wounding remains fairly broad thereafter but soon tapers off. The recovered bullet may remain intact to some degree (confirming that the bullet did not blow up on impact) but may be found flattened out against the offside hide or in bone etc. Depending on the impact velocity, the bullet may not go much further that 12" when used on light to medium weight game. So what does this tell us? Well, its pretty obvious. The 250gr driven at high speeds is adequate and yes sometimes a spectacular killer of lighter animals. But if one is looking for a good balance of wounding versus penetration / game weight versatility, a heavier 300gr bullet is a better choice. The simple fact is, the 250gr pills have a very low SD.

There are certainly a few ways to manipulate performance. A tough lighter weight bullet does of course enhance penetration compared to the baseline conventional bullet performance described. A heavy but soft bullet can also produce deeper penetration, not only as a result of the increased SD, but also the reduced muzzle / impact velocity. And of course we can always combine the two (tough construction + weight) to achieve even deeper penetration. Whatever the case, the key is to match the bullet to the job at hand. The .454 is certainly a good energy dumper. It also works very well after velocity falls away.

The comments I have made above should lead to obvious conclusions regarding the .444 and .45-70. The .444 has high SD options as well as soft point and bonded projectiles to choose from. The .45-70 can be loaded with much heavier 'off the shelf' projectiles. But going back to your question Marcos, a 300gr Hornady or Sierra HP is adequate for Red deer and boar in the .45-70. More info can of course be found in the Knowledge base.

A potent lever action is good in theory but these rifles can sometimes let us down. A poor fit, heavy triggers, a wandering zero under high recoil etc. A bolt action can be nicer to tune but then suddenly we find ourselves shooting a .458 Win Mag which is not exactly compact.

I suppose it really depends on what one is looking for, the type of game hunted, required rifle weight, expected accuracy etc. Terrain and expected ranges are important considerations. Close ranges do away with the need to worry about trajectories. Longer ranges are a bit of a concern. A higher speed may produce a flatter trajectory but can also place stress on some bullet designs when shooting at very close ranges.

I don't know if that helps any.
