I'm in the process of putting together the specs and components list for a custom build, I'd like to have completed this year. This rifle will be used for mostly hunting deer at ranges out to 1,000 yards. Going into this project I've got a couple of requirements. 1) 300 Norma Mag; from everything I've read this cartridge has a lot of knock down power. 2) Suppressor; protecting my hearing is very important and I understand that even a couple of shots taken every year, while hunting, can be very harmful. 3) Lightweight; I hunt on foot, so having the absolute lightest rifle possible is a requirement.

As I've thought through this build, I've relied heavily on the experience and viewpoints, found on forums, internet searches and the guys at my local gun shop. I imagine there will be some questions regarding some of the decisions for this build. So, I'll address those questions first, before asking my question in regard to barrel length.

1) Why 300 NM; I want a cartridge that I can be 100% confident will drop animals in their tracks.
2) Why Suppressed; Protect my hearing. Also, lots of people are getting them and I want to be included.
3) Why Lightweight; I generally hike 10-15 miles a day while hunting. As they say ounces=pounds=pain.

Now on to my question. I understand that 300 NM's typically have 26-28" barrels. But, by the time I add a 7" suppressor, I'd be up to a barrel length of 33-35". Which is too long considering how much time I spend hiking in brush. I'm leaning towards cutting the barrel down to 16". Giving me an overall length of 23" with the suppressor attached. Recognizing that the 10-12" of barrel loss will result in a decrease of ~350 fps, according to a guy on Snipershide. I am expecting the 300 NM velocity, shooting 225 ELDM, to be ~2775 fps. By comparison that's approximately the same velocity of the 300 NM's smaller .30 cal brother, a .30-06 shooting 178 ELDM, in a 24" barrel. I understand that we're not comparing equal bullet weights. The sacrifice in velocity is worth it to me. Mostly because I'll be shooting a suppressed magnum. Which honestly, just sounds Bad A$$.

Also, I know this gun will have a lot of recoil. Recognizing the importance of getting a really good zero, I plan on using a Lead Sled, while sighting in my rifle. This will remove all of the variables of me as the shooter and get the scope really dialed in. My experience as a hunter is that I am a much better shot on game than at targets. Looking back at my track record while hunting, I think it's safe to say that I'm a "quarter MOA shooter all day.....if I do my part"

Finally, if you have any recommendations for which scope to use, I'd really appreciate it. My preference would be for something in the 25-35x magnification range. I subscribe to the idea of aim small...miss small. Considering the distances, I could find myself shooting, I'd like to be able to really zoom in and shoot at a tuft of hair on the vitals. As opposed to a deer that just looks like a silhouette in my scope. I haven't started looking at scopes yet. But, am inclined to consider something from Vortex. Based on what I've heard about their incredible warranty program.

So, back to the question being asked here in this post. Do you think I should go with a 16" barrel length. Or, should I accept the increased barrel weight and length, by stepping up to an 18" barrel?
Dave, if we ask you questions about your intended use, or your experience shooting magnums, or your current accuracy at distance ... will you get pissy with us? ;)

Edit:
I guess you need to read the entire long ass post to sort out the trolls, lesson learned
No ... just the first three lines.

Such a shame you didn't leave your original response there for posterity ... would have allowed everyone whose posts you've attempted to denigrate with a "ha-ha" emoji to repay you in kind. Ah well.

You will destroy your supressor and barrel. Not enough barrel legnth to burn the powder.

I love my norma, but at that legnth you'll just be filling the barrel with unburnt powder creating a time bomb.

Why limit yourself with the extra barrel length? You already have to go through the system for the Supressor Tax Stamp, just apply for a second tax stamp as a Short Barreled Magnum, 13 inch barrel plus 7 inch supressor makes it a perfect, compact fire breathing bastardization of a Long Gun.

WRO, my post was a tongue in cheek response to the original ,1st post at top. I will delete my satirical post.

I wasn’t responding to you..

I wouldn’t dream of running a Norma with less than a 22 and I would sacrifice velocity to run a faster powder.

Go back and read the first post.
What is your understanding of the word satire?
