Guys lets talk. POWER POWER POWER in the short action rifle

[backwoods83]

Well according to matrix there .277" cal 165grn vld has a BC of .738, so the combo I posted of the 270x7mm wsm improved will have 3870ftlbs of energy at the muzzle with 1544 remaining at 1000yrds and will stay transonic to 2000yrds with 503ftlbs remaining.

That is why I like my Norma,@ 1700 yrds w/300 grn. it still packs 1204 E

daaayum!

I dont know what either of them are, but I"m assuming we can get more foot pounds out of larger diamiter bullets.

I just read the whole thread over, as it was more than a year old. I guess what I was looking at when I first started the thread was a SA round that would operate as a repeter. I chose the WSM bolt face as thats what I had, however I would not be apposed to thinking outside the box. Like using a .585 bolt face and basing the round off of a 338 lapua or 470 nitro something like that, again just throwing out ideas.

How about the 7mm Fatso?......Rich

Lazzeroni's 7.82 (.308) Patriot is the most powerful 300 short-mag in the world ,,,, see Short Magnum Cartridges ,,,,

I bet a 6.5 RUM would be a scorcher. With a 130 Scirocco it would be a true screamer.
With the 142 smk you would also be running them very fast.
Then there are the Carteruccios and maybe some new Wildcat bullets.
Not sure how long you can nurse the barrel along, but it would be a flat shooting cartridge with lots of energy.

remembering what Ackley had to say about the 6.5 Rem mag, I got a big smile

[Trickymissfit]

Just to restate my orginal intent guys. I am not looking to chamber LA rounds in a SA! I am asking or opening for debate your ideas on how to get the most powerful SA based round we can for LR hunting.

Lets set a guideline. the rifle will operate as a repeter just for the reason of keeping the topic on SA length rounds.

well just a thought, and probably not a long range round as well, but with enough power to work on 98% of the stuff encountered in N. America; look no further than a .458 American. I think there's also a 2 inch .375 version of this round, and a .338 or .358 is quite doable

the 169.5 wildcat has a little higher bc than the matrix but not much
1544 lbs will put an elk or moose down. Goodgrouper did some testing on elk shoulder bone and told me 800 lbs will break the shoulder bone.

So much info here just not sure that 7mm fatso has come up time and again.

 

[theflyonthewall]

The Fatso would be awesome if one didn't have to use so many steps in forming the brass. But when your really breaking FAR away from tradition, what other choice does one have?

I agree, the 338 something also has me thinking.

 

[theflyonthewall]

Well by all means allow me to add to the conundrum.

How about starting with a 300 SAUM case, neck it to .338, then blow the shoulder out enough to add another 15-20 grains of powder?

In theory, this would be pretty easy to do. Probably not THE most energy-packed possibility that's been discussed, but certainly a feasible heavy hitter.

If you want short actions and magnum performance, that's about the only option you have unless someone chops and necks a BMG......Rich

Not to be arguementive but if you blew the shoulder forward enough for a 15-20 gr. increase you would have a straight wall case(somewhat like a 50 S&W......Rich
