I think I may give up

[CWLONGSHOT]

Tomme I also have a 300 Blk Bolt that I like allot. (Im loading for it right now!!)

Im strongly considering a 300 HAM'r barrel for my SCR thats currently a 350 Legend (9x45). The hammer is gonna be 200fps "better" then the BO with a more conventional twist. That should be more friendly to cast. But while back I spoke with Bill Wilson via email and he said chambers are very tight to better handle Pressure so would/may not be cast friendly. Guess Ill find out. "Everything" doesn't have to shoot cast I guess...

@Tomme boy , does this rule out cast flat-noses and similar, meaning without a HP?:

"...shooting an expanding type bullet..."

Our pistol barrel minimum is 5", which is the only niggling little thing about our rules that I think borders unnecessary, but Id not want to be the one who has to winnow that pile myself. This rules out the very common 4 5/8" and 4" guns, so many of which are perfectly capable of taking deer in an appropriate chambering. I was grateful that Ruger chose 5.5" for several of their SA models because of this. It's still a handy length, but I once had a 4" N-Frame 45 Colt that I couldn't use.

Where do they measure the barrel from? In Wisconsin they measure from the rear end of the cylinder, which when you think about rifle and shotgun barrels makes sense. You don't measure from the front end of the chamber, you measure from the rim end of the chamber.

We actually changed the cartridge laws here this year. It is now ANYTHING 35cal and larger. Does not matter if it is a bottle neck or not. Local gunsmith has done over 100 35 whelens in Savages and Remingtons. He is buying barrels from someone already set up for barrel nuts and putting them on for the people.

I am thinking a 300blk. The Ruger has to stay with the same bolt. It is a conventional bolt. So I will have to stick with the 223 bolt head.

You could do a 30 Herritt (SP) on a 22 Nosler . You get the extra case capacity of the 6.8 case that's about neck length longer than x39 and keep the 223 rim .

Like the rest of the revolver world measures revolvers' barrels - just the barrel, not including the chamber.

Sure would be neat if they did it the other way though.

I don't complain too much about that, because I personally like the 5.5" barrels on SAs for handling and the sight radius, but it would be neat to have a 4 5/8" New Vaquero and still be able to hunt with it.

 

[CWLONGSHOT]

I always like the 5 1/2 best for looks and 4 1/2 for handling. I have more 4 1/2 and (4 5/8 Rugers) 7 1/2" then 5 1/2's!!



We need 6" here for a legal hunting Revolver.

 

[300BLK]

300BLK is VERY efficient. Most of the new 300BLK barrels are pistol length gas, so would require an adjustable gas block for shooting hot supers. 300Hamr is just a slightly modified 7.62x40WT. Its 1mm longer, but the magazine length is the real limiter, so no real advantage from capacity. The X40 holds about 6gr more powder than the 300BLK, so would seem like a bigger hammer, but not so much in reality. I have a 12 twist X40 and haven't seen a real advantage over the 300BLK (7 or 8 twists) with cast bullets. The 300Hamr is supposed to be tighter in the throat, so might be a jacketed only proposition short of throating.

I've been toying with the idea of a 277 Wolverine, but the lack of jacketed bullets is the hold up. It has the advantage of speed and bullet weight between the 556x45 and 7.62x35 or X40.

 

[CWLONGSHOT]

Im on the verge, of go, on a HAM'R. I had a large expense pop so it could be pushed back a bit. But if ya would Id like ta chat some weekend.

I keep looking at the Wilson Combat barrel for the Ruger. $200 and everything comes with it. HS gauge, barrel nut, and wrench. But it is out of stock right now.

Let me ask this? Could you use 300blk dies to for the cases? And one thing has held me off was the 1-15" twist. I think that is a little slow. I think a 1-12 or a 1-13 would have been perfect.

When i was shooting benchrest,15 twist was THE twist,for 125 jacketed.

I made 7.62x40 brass with 300BLK dies. 300Hamr brass is backorderable from Starline and would be my recommendation.

As to the cast bullet here it is allowed in any form from what I hear. I know I have been checked with a 357mag and I had SWC 158gr bullets in the gun. DNR guy never said anything. The way I see it, they think anything lead will expand.

IINM he sells BOTH 1:13 & 1:15... Maybe he used to...

Not needing to shoot heavier then a 150 and vast majority of the Bullets being under 135g Im not as concerned.

I grabbed a set of LEE dies for 20$ (new) last week. I also ordered a chop saw guide.
I have just hit go on my Birthday order @ Midway that included 135 FTX and HAM'r Brass

Barrels are on sale @ Wilson. I just had a 1k expenditure I didn't expect, or Id have the barrel coming too...

No need to rush. But my own desires.

Using GRT to compare BO & 30Hamr, Hamr gets 200 fps greater with H110 and 125gr SST. 53K psi. I crony'd 2150 fps 145gr PB with H110 in an 18" 1:10 BO AR. With the 125 SST I should get 2300 fps. Not enough diff for me to change.
loaded 23 rnds of 170 gr PB (RD clone) with 8 gr WSF for fun this morning. Should get 1400 fps. from the CVA SS. Family meeting at the ranch Thanksgiving week so take the CVA for kids to shoot. She's sick today, maybe got some bad salmon for lunch yesterday.

That pretty much sums it up. Hodgdon's data shows a high of 2402fps from a 16" 300BLK with Lil Gun vs 2557fps from 18" with a 300Hamr and CFE BLK and 125gr. Other than these, the Hamr is 2300-2400fps and th 300BLK is 2200fps. Both will go faster than Hodgdon's data by pushing pressures up to ejector swipe territory.

We chrono'd 110Vmax over 19.4gr H110 (300BLK) last week and saw 2400fps from a 16" RARR, and 2295fps from a 16" AR w/carbine gas. 300BLK will shoot heavier bullets accurately because of the quicker twist, and will also shoot heavy subs for those who choose to be stealthy.

For 300Ham'r, expect to BUY Starline brass because making it from 223/556 is a time consuming PITA.

 

[CWLONGSHOT]

200 ft./s is about advertised advantage over the black out in reality. Sometimes it's not even that much. I've often said I wish I could buy a Blackout barrel with a one and 10 twist 20 inches long but for whatever reason they just don't make it with anything more than 16 and of course everything is one and seven or faster.

How much would a longer barrel gain with a efficient a cartridge as the 300 blackout not sure. And you're right it's not a large improvement in performance but it is an improvement.

My barrel is a Stainless fluted McGowan, 18" 1:10, carbine gas. Chamber is a little tight but it shoots good. Haven't chrony'd the 110 vmax loads, should be 2300 or so. Only problem I had with the barrel is they buggered the threads so I can't put a protector on it. It has the Rattler thermal on it (after I just did a update that works), my night hog gun.
CW's barrel would be 450$ US.

 

[Tomme boy]

The barrel for the Ruger American only comes in at the 1-15tw. He does have the faster twist for the AR barrels but not for the Ruger.
