300 Ham'R

[Bearcatrp]

Given that with the 110 TTSX I’m getting 2400 with the .300 whisper/blk out of a 10” pistol AR using H110 (Barnes load, it’s notorious for being a bit hot) I really doubt the HMR is really that much better.

You will have to pay WC prices as well, so color me dubious of any great advantage.

BTW, the Grendel is crap... you want the 264 LBC.

What twist on your 10 inch barrel? I would say that's a hot round. Am getting 2200 fps out of my 10 inch with 110 v max.

Not sure the twist. It’s a factory APF pistol that I got for deer hunting. It shoots 1.25” at 100 with this load.

The factory Barnes ammo is 2200. The manual says around 2300.

The max load Barnes gives with H110 is what I’m using, and yes, there are some pressure signs, but it functions well. Low SD, accurate, so I use it. Only new cases, and the brass gets lost while hunting. The work up loads showed flattened primers, but no worse than my IPSC open ammo, so for my limited use it works.

Am not sure 2-300 fps is worth the cost involved. Does make you wonder if a 300BO with a 1:15 twist can get close to wilson combat numbers. Of course only 150 grain and below according to the info on the 300 Ham'R. There is a post on 300 BO forum claiming 2700 fps with with a 110 grain bullet using shooters world socom powder.

Wasn’t the whole point of the blackout to shoot subsonic projectiles through a suppressed rifle? There are plenty of other cartridges to choose from if you just want more velocity, but that sort of defeats the purpose of the .300 blk. This is like saying that the .223 is “better” than the .22LR.

will it accidentally fit a 223 wilde chamber like the bo = i would not

Clearly the purpose of the .300 whisper was this. I think the bo is trying to be many things to many people.

Yes. My 10 inch suppressed BO shoots great. By extending the brass so you don't use a pistol powder from what I have read so far. Still on the fence if its worth it or not.

Exactly, I’ve never fed mine anything other than subs.

I thought suppressed only was the purpose of the .300 Whisper.

The Blackout was supposedly a multi use platform for getting heavier bullets out of a AR.

As I recall the gun rags were all over its versatility over the .223, and how it had almost as much punch as the .30 short Russian, while fitting in the standard AR platform.

That it fits into a .223 chamber is a concern, but I personally don’t have too much trouble keeping ammo and weapon matched. It probably helps that I don’t play musical uppers at all.

The way Wilson tries to claim that the Ham’r is god’s gift to hunting is a joke... a couple hundred FPS with bullets that are more or less identical hasn’t made a difference that I have seen. That the gunwriters buy it is comical, and then folks believe them is sad.

I agree that modifying the case to avoid allowing the .30 to chamber in a .223 is a positive safety point, but still it’s the user’s responsibility; lots of potentially dangerous situations out there- like high pressure loading of old cartridges that could be put in an older gun... the .45-70 being classic.

I was under the impression that whisper and BO are nearly the same. Hornady says you can shoot their whisper in BO and the some dies are setup for both.

I think there are better supersonic rounds and the subs from BO in my experience work nicely suppressed.

Yeah, I didn’t think there was any actual difference between the two either, just more of a branding thing.

I think he means Yes Ghost is right and No Ghost is not wrong.

[Holland&Holland]

That goes without saying Ghost.

But what I meant was while the 300 bo did mimic the 300 whisper and both can generally be shot from the same chamber the whisper predated standardization and therefore that statement is not exclusively true.
