It Will Be A 6.5-300Wby After First Of Year

[remingtonman_25_06]

Hey I admit, I have very little actual firing knowlege with wildcats, (only one I owned and shot for is my 338 EDGE, but its a simple neck up through the die) but I do a fair amount of reading on the net and inparticular some LR sites where there are guys who do shoot a lot them (wildcats), so I usually know whats what still.

3400-3500fps with 140's in a 26" bbl is not likely. You might get close with a 30" tube.

Anyways, wildcats are definately fun and exciting, I understand that, but there becomes a point where it really does no good to burn more powder then is neccesary down a small hole, to gain more velocity, you have to have more barrel. Even then, there will become a point in which either you'll top out on case capacity or barrel length.

Of course the 264 WM aint got the cool factor of the 6.5-300 WBY but thats all just a name. You put them in equal barrel lengths and theres really not a whole lot of difference between the 2, and really the only difference is your burning 15g more powder in the WBY to gain maybe 100fps.

Not here to tell you what to get, I just wanted to offer some ballistic advice that might help you get to where you wanted to be.

+1 Remmy, to get top velocities you need a long barrel and slow powder. The H870 Bullet has is good, but the Surplus powders (WC868, WC860, WC872) would be even better. With surplus prices, who cares if you burn a few extra grains.

Bullet, the one thing I would suggest is going one step heavier on the contour, a #4. This will help limit barrel heat, with can extend the life of the barrel, and the stiffer the barrel, the better the accuracy. Since this is your "reach to the end of the gas line" gun, that might be something to consider.

More importantly, I'm just happy to see you break into a new area of the sport. But I must warn you, it can very addictive and lead to the conversion of large quantities of gun powder into loud noises.

You know that 270/300Wby I was going to build after I finished working with the 257Wby is not looking so bad at the moment. I could get away with a 27" #4 and be in good shape and not quit as over bore. Sure glad I have got a lot of time to think about this. I have had 7mmSTW's 257/300Wby and way in the past a 7mm/300 (off the win case). This will be fun but I really need to do this right and pick the 6.5mm, 270 or 7mm to work off the 300Wby case looking for fast flat trajectory and accuracy. Told the GunSmith, glad I got three months or so before I send the Action and the stock. :grin:

Yep!...............Havin some speeeeeedy screamin fun in certain cases such as too much overbore is ok, but it does come with a price!!

I like the 6.5s too, but geees! Next thing ya know, somebody will try a 25 or 6.5/460 Wby!...........Barrel cookin time!

At times Big Squeeze you don't understand because you have never gone where some of us have gone with wild cats and you have not enjoyed what we have experienced that can't be found in a book. Somethings just have to be lived for one to intimately understand. What you don't understand is the fun no matter how brief a time the fun last.

Now I have always liked you and we have known each other for quit a while now and we even have a lot of common interest, but sometimes you really don't know what you are talking about. It is not due to the facts of factual knowledge but it is because of your lack of actual real time experience with certain cartridges that limits your vision.

Antelope Sniper is right, it is and will be fun. You might ought to try something before you express such strong opinions. If you did we would be willing to listen more easily to your commentary. Now I did not say you could not nor should not express yourself, but you must come to grips with some of your limitations in what you really don't know.

The world is not just the 300WSM or the Ruger 375 although I know you know much more than those two cartridges. But why don't you reach out and stretch your experience if only once and for a short period of time. I promise it will expand your understanding and be a lot of fun in the process. Your friend, bullet

..............................Bullet!.....A very interesting reply!

However and with all due respect! It does not take ownership, reloading and shooting experience with a specific wildcat cartridge to recognize overbore in a cartridge when it is plainly there to see. The fact is, a 6.5mm/300 Wby IS an "overbored" cartridge. So what you may think of me as not knowing something because of my lack of experience with a certain cartridge, does not mean that I do not know of its characteristics with regard to certain effects on a rifle bore.

True! I`ve never personally owned a wildcat round, but that doesn`t mean that I haven`t read about them, or have not talked to people who do have them now or did own them at one time.

In fact, I do understand the fascination for the wildcats rounds and certainly hope that people have fun shooting them. That does include you after you get your 6.5/300 Wby. I hope you have alot of fun with it, regardless if you only get 500 rounds through the barrel or 10,000 rounds through the barrel.

I wasn`t trying to take away your future fun with the 6.5/300 Wby or demean that cartridge, which was probably what you might have assumed. Strong opinion or not, I was merely stating facts about this particular round. And I do understand that certain things can be short lived, but which are a helluva alot of fun along the way.

Because I have an opinion about a cartridge which is based on fact, even without the personal experience of owning one, "doesn`t" mean that I don`t know what I am talking about in reference to overbore.

And lastly! I can well assure you, that my experience with cartridges goes well beyond a 300 WSM and a 375 Ruger, as in the past my experiences have been "well" strrrrrrrrrrrrrrrrrretched!

Good luck with the 6.5!

Novice question: Wouldn't a 7mm-300WBY be identical ballistically to a 7mmRUM?

 

[remingtonman_25_06]

Richracer

I"m thinking the 7mm-300 WBY is basically a 7mm STW. They say to start loads with the STW anyways, the 7mm-300 might out do it by a little, but not much.

The RUM case is a little bigger then the WBY case.

The STW and WBY are more similar, I think.

Could be wrong though.

Bullet

The only problem I see with .277" is lack of high BC bullets.

Berger has solved a little of that now, but your really limited.

I'd personally rather have the 6.5 then the 270 anyday for just that reason. Lots and lots of good LR bullets.

Your points are well received by me as you know and thanks for wishing me good luck. I probably will need it.

Yes, it is a lack of BC for the .277. I do need a bean field rifle.

 

[Antelope_Sniper]

Remmy, I came to the same conclusion you did. The 300 bee is very similar in volume to the 8mm Mag (parent of the 7stw), and 6.5mm bullet selection is excellent. I just wish Nosler offered an BT/AB in the 140-145gr range for the long range hunter.
If Bullet decide to use the 140gr CC to shoot deer, I would be able to hear POP's scream from Cheyenne all the way down here in Denver.

 

[bullet]

Let me stop this before it goes any farther. Sorry for the thread. I have weighted the evidence of the 6.5/300Wby, the 270/300Wby and the 7mm/300Wby and have decided that I will chamber my rifle in 300Wby again with a 27" #4 barrel and that is that!!!!!!

 

[Antelope_Sniper]

No need to apologize, we enjoyed the thread (or at least I did). Besides, it helped you decide on a 27" bbl and the #4 contour, both of which I think you will be very happy with. You already have alot of good load data for the 300 Bee, and you will be in a great position to move your game to that next level. The 300 Bee can throw a 125gr NBT close to 3700. Sounds like a good platform for a beanfield deer rifle to me.

Glad you enjoyed it Antelope Sniper, I found it stress me but it did bring me back to my senses knowing as Big Squeeze has said he could not see me without a 300Wby and he is right.

.....................................YEP!.........So! I don`t know what I`m talking about uh?.......... :lol: :lol: :lol: :lol: :lol:

Soon after you would have gotten that 6.5, you would have had a great deal of buyers remorse, because your 1st love in a cartridge, is the 300 Wby!!

Hopefully, the wind around your house will remain blowing in the same direction,,,,,FOR AWHILE!!! ol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol:

 

[jtoews80]

Wildcatting..... It is a disease, HELP!!!!

i somehow find this all a bit amusing. The closest I've been to overbore is a 30-378 wby and a couple Ackley cartridges just recently, so I still have to build a decent wildcat rifle myself to scratch that "itch" at some point.

There is something delightful and almost sinful about having a rifle that is almost entirely useless and totally impracticle.

In relation to my 30-378.

To burn 110 grains of powder in a $5 case to launch a 180 grain .308 bullet @ 3500FPS isn't reasonable or needed when hunting WT deer @ 100-600 yds, but it is alot of fun. Barrel life isn't great, reloads cost $22/box in canadian dollars and you can't afford to loose 1 piece of brass.
That is why it's fun. I'd love to try a .257 RUM or 6.5mm RUM, but they are not going to outperform a 7mm RUM by enough to merit the custom reamer and dies.

What I have in mind is a 6mm WSM with a 44 degree shoulder and the ability to shoot 115grn DTAC's @ 3200-3400FPS. This will make any coyotes life around my farm a lot shorter.....

...................................... Well put and you "you do know what you are talking about (sometimes :lol: :lol: )


Sometimes uh????...........Read on another forum where the 300 Wby can be successfully loaded up with some RL25 using ONLY a 150 grainer with MVs @ 3700+ fps, with pressures from the high 60K to the mid 70K range.

Does this appear OK to you? Max book velocities list 3400-3450 fps range.

Apparently, some guys have been experimenting doing that, with no signs of pressure from the MK5s............

 

[Antelope_Sniper]

BS, how long are those barrels?
29-30"??

 

[Big Squeeze]

BS, how long are those barrels?
29-30"??

.........................That was my first thought too!

You can go here, read the thread entirely and see for yourself what was stated.

"24hourcampfire.com"............then go under the "hunting rifle" section (Pg 3) and then see the thread titled.........."300WSM vs 270WSM as compared to their peers".........Then go to pg 6 of that thread where the original poster (340 Wby) stated he was able to accomplish 3700+ fps with RL25 using a 150 gr bullet only and from a MK5 only.

I didn`t see any barrel length stated, but the std MK5s are 26" so I assume he was referring to the 26" ers.

You`ll find it interesting! Happy reading.

I post there too on that site including on that thread, as I`m a member over there as well.
