I've got some h1000,h4831,h4350. Using a tikka action for the build. Haven't decided on what scope yet. Thinking an shv but they are kinda tanks for what I'm trying to accomplish with the build

I like the Swarovski z5

@laker, prepare to get beat down by a bunch of people that will tell you not to do it because they know better, and also have never done it themselves and have zero first hand knowledge.

If you want to talk to people that have done it, the specialty pistol threads will give you a good idea. Maybe @Ernie will chime in....I plan on referencing his videos anyway.

What people don't seem to understand, is yes, you know you will loose performance over a 28" barrel. Not sure why that is a main focal point, as that is rather common sense, but it is, nonetheless, a main driving point people bring up.

Also, no, other much smaller cartridges won't give you equal performance in the same length barrel. A 20" 7 saum will not rival a 20" 28 nosler. If you compare a 28" 7 rem mag to a 20" 28 nosler, ya, you will likely be similar. But the point of a 20" barrel, is so you DON'T have a 28" barrel.....

Also, faster burning powders won't "necessarily" give better results than the standard powders one would use. Talk to those that have done it, they will tell you that the same powders that get top velocity with long barrels, still get top velocity with short barrels. Also, the vast majority of powder is burned prior to 20" of barrel, even with slow burning powders, quickload even confirms this. The large muzzle blast you get is not "unburned powder", it is unused pressure expanding closer to you. All a longer barrel does, is allow the remaining pressure from the burned powder to impart more velocity on the bullet, powder is not "still burning" in the vast majority of cases.

Cases where you "might" get better performance from a faster powder, is when high muzzle pressures "may" cause some turbulence, causing variances in e.s. and possible accuracy problems. However this is not the rule. There are people running powders like rl33, retumbo, H1k, you name it, in shorter barrels getting great accuracy and teens or lower e.s., so it is not set in stone, just do load developement like any other rifle of the same chambering.

Then people will talk about the horrible, face melting muzzle blast that will instantly incapacitate grown men. Well, watch a couple videos of this kid shooting Erie bishop's 7mm Dakota...he doesn't seem to have any problems....



That is pretty much all the arguments that will come your way why not to do it, most of them are at least partially unfounded. Bottom line, no, it's not for everyone. Yes, you have more muzzle blast, certain brakes can help mitigate that while still giving good recoil reduction, but your gonna be using a can anyway, so that entire argument is now gone. Yes, they handle WAY better than a 26" rifle. Yes, you loose performance, a 20" 28 nosler will be on par with a 26" 7 mag or so, your not getting the full potential of a 28 nosler. Well, neither is a 26" barrel.....you would probably need something along the lines of a 35" barrel to get "full potential" of a cartridge like that, maybe even more, but does anyone carry one of those around? Likely no, a 28" handles better. A 26" handles even better. A 24" handles even better. A 22" handles even better. Guess what.....a 20" handles even better!!! And 7 mag performance, out of a 20" or a 30" barrel, doesn't really matter, is still capable 1000 yard hunting performance.

Sorry for the long post, but figured I would throw you a heads up.

I don't normally quote posts, especially long ones like these because it clutters a thread, but this is some of the best information on the whole barrel length topic I have seen in a long time! Thanks for putting this together.

Oooh and I say go for a suppressed 20inch 28 Nosler if you think you can find the right powder.

What powder are you using to get 175 going 2900? I was hoping for 2750-2800 with 180 grain Berger vld so looks like I should be in the chips. Curious to hear how the 20" 30 nosler goes. That's on the short list of builds I'd like to do. Just waiting on the reamer to show up and I'll have a 20" 7mm Sherman max done.

I had a 22" 7 wsm throated for 180s and I got 3000 fps, 2850 with 195's.
I looked into the 7 max but ultimately decided to spec a custom 7-300 wsm 45 degree improved.
I just screwed the barrel on my tikka tonight and fire formed a couple cases to get an idea on capacity, 82 grains!
The second pic is a formed case next to a saum

A 20" barreled 28 Nosler should do anything a 24-26" 7mm SAUM will do, I think it's a great idea. And I'll second everything that Codyadams said. The only sacrifice you make with a short barrel is about 30 fps/inch of barrel.

I've had a 14" 300 WSM, 18" 300 RUM, 17" 6.5x338 RUM improved, 18" 338/375 Ruger, a 20" 338 SnipeTac, along with a bunch of more "moderate" chamberings in barrels 20" and shorter. All of them gave the highest velocities from a short barrel using the same powder which gave the highest velocities in a long barrel. That doesn't mean the same powder was the most accurate, but the velocities were highest.

The muzzle blast won't be an issue for you since you're shooting suppressed, but a big muzzle brake that close to your face can be a bit intense. That's not necessarily a result of the increased blast caused by the short barrel. It's also because your face is 6-8" closer to the blast. I will admit though that my 338 SnipeTac pistol burning 140gr of H50 BMG with a Terminator T5 brake is pretty abusive! LOL
 
I'm really amazed at the velocities Ernie was getting. Really amazing, I need to get on the ball. I wouldn't mind a 7-08 and a larger 7mm of some sort.

I have really toyed around with the idea of making like a 6.5 max in a pistol, built on that manners pistol stock....would be a sweet pronghorn set up!

Opens up questions on optics for LR handgun. But that's for another thread. I was running the numbers on say a 180 Berger at 2900 fps. Impressive. That 175 or 180's proven bullets at distance.

Absolutely, he helped in my choice of building for my suppressed 30 nos. And ya, it's not for everyone, especially if your running a brake vs can, some people just have a worse reaction to muzzle blast. However, others like myself and my wife, don't notice it, we shoot those rifles with earplugs when hunting anyway, and I double up at the range, with any gun, for that matter. I'm a firearms instructor for my S.O., so I am around a lot of gunshots.

But if you want a sweet handling, 1000 yard + capable hunting rifle, a short barrel accomplishes the sweet handling, and a big chamber gets the 1000+ capability from said short barrel.

Our shop built a 20" 30 Nosler on a heavily modified Rem 700 short action- suppressed.
It's pretty rowdy but performance is still pretty impressive, even with factory ammo.
Been a while since we shot it, a year or so, so I can't remember the numbers off hand, I just remember they were much higher than we expected with Nosler 180 Factory and Nosler 210 Factory.
