Home Forums Hunting & Shooting Hunting Rifles Pronghorn caliber

🙄 Post up a link to a new 6mm Rem the OP can buy that will stabilize that bullet…..I’ll wait. This post is about the OP’s caliber of choice, not your antique.

If the 260 Rem had the proper twist, the 6.5 creedmoor wouldn’t exist, same for the 6mm Rem and 6CM.

No sure you can run the Gamechanger in a 6mm Remington SA and not be seated too deep. I have some at home I should seat to 2.8" and see if the ogive is getting below the case mouth.

Since you have that switch barrel rifle ( I'm jealous BTW) I would set up two out of the three best- .243; 6.5 Swede; 30-06. But would load the Barnes 80TTSx to 95 NBT in the 243; the outstanding 120 NBT for the Swede (or 125PT) and either the Barnes 130TTSX or 125 NBT in the 30-06 (but don't go over about 3000 n the 30-06 with the 125NBT). The "Wind" out on those short-grass praries are demons from hell! ha Take shooting sticks and take your shots from the sit (hard to get prone most of the time what with taller grass/weeds, cactus and more cactus) Hopefully you have the right tastebuds for them. I don't...may as well be roadkill for me, yuck! ha I get it processed then give it away to those friends who do like it. Its beautiful meat, just too "goaty" for me. Take two rifles if possible or at least shoot your partners rifle so you can use it as a spare, scopes go out, trash gets in the trigger, several things "can" happen to any rifle, I'm sure you know this, just saying. have a Ball! They are so pretty, move all during the day, a great hunt to take a youngster or first timer out to hunt.

The Ruger American should handle it but if buying a new rifle I would go Creedmoor if something other than a 243.

10 gauge

My 6mm is a Rem M Six and NOT a short action in the true sense. Magazine is long enuff.
On top of that, I have loaded and shot 'compressed' loads for years. ie 7828 in 270 under 130 s.

Mule Deer has talked about this principle more than a couple of times.

I don't own nor will own a true S A rifle.

17 fireball in a long action just makes so much sense......

Wasn't talking compressed. Was talking about the sleek ogive being in the case mouth. Doubt it hurts a damn thing just mentioned it.

And I was talking the diff in a Pump rifle magazine compared to a S A bolt plus compressed loads.

No Harm No Foul

I should get out and try some in my BDL 6mm. They are loaded to the lands and won't fit the mag.

Should see how they shoot or look like a shotgun pattern.

Tomorrow I will measure my magazine for the Mod Six 6 mm.

I have no doubt it is longer than a S A bolt mag.

John, as an aside, I believe I was in 8th grade when I read the hunting story you wrote about the young hunter and your .220 Swift, approximately 1984 if I remember correctly. I remember that story well, as it was one of my favorites and led me to one day owning a .220 Swift, which I still have.

I have measured and taken pix of TWO diff pump rifle magazines (clips grin)

First, some people mistakenly believe there are S A & L A in 760s, 7600s & Sixes.
Here are the mags from a 30-06 (L) and a 6mm Rem ( R)



NOTE: the OAL of both magazines are the same. The followers are different to accommodate diff cartridges.
I can take pix of my Model Sixes in 6mm Rem, 270 W, & 30-06 > the pump mechanism is the SAME length for all.
There is no bolt stop to shorten the pump throw (action) in a 243, 6mm Rem, 308 W etc.


Second >> here's a pic of the magazine for the 6mm Rem.
I have measured to my BEST ability using one hand to place the micrometer and the other to take pic.



I apologize for some glare. That's the best I could place things for the pic.

The 6mm Rem INSIDE max length is 2.955


UIM (unless I'm Mistaken) that is longer than most S A bolt magazines. That allows for longer seating of
long 'slippery' bullets.

NOTE ! Due to photo management of my Imgur account >> These pictures will disappear in a week or so.

So I am not the only one that ran into the 6mm mag length thing in my Remington.

All the more reason to use the 85hpbt I guess.

Still have a few loaded but will have to revert to 100 Pro Hunters because of the damned shortages.

6 creed or 6-06.

I`ve been lucky enough to have killed a few with my 250AI and 100 grn Sierra`s. One year I felt the need to take the Sharps, 45x110x 450 PP bullet using irons only. No range finder at the time.That was a challenge, and balls of fun. Try it.

You can always run it as a 2 shooter like I do if loading to the lands. 1 in the barrel and the one in mag isn't actually down in the box.

I have some 90 grain Ballistic Tips that are at mag length and shooting under 1/2" so I am no longer worried about loading long.

abbydog,

Is your switch barrel rifle user friendly and easy to hit with in the field? If so, any barrel that you put on it will be good to go

For a lot of years I carried a Ruger 77 .243 as my primary hunting rifle wherever I went. And I mostly used an 85 or 90 gr bullet for about everything I shot.

I choose my rifles based on looks almost as much on performance. And it's gotta feel good in my hands. And it's gotta shoot where I look, and do so from field positions

If you've got a rifle you like to shoot, take it with you wherever you go and make it your antelope, deer, coyote, and bear rifle

If I'd started life with a .250 Savage (or a .243) in a model 99, I'd likely still be stuck there. Because I wanted to be.

And I am a fan of High B.C. and velocity...

But give me a good looking good handling rifle that I can hit with at 200 yards or so and get out of my way while I hunt.

Bring the one you shoot the best.

It's 98% about your abilities and 2% about the tool you use.
I have killed pronghorns with the following.
243 Ruger #1 Scoped
6MM Remington Scoped
25-06 Mauser Scoped
6.5X54 M/S (iron sights)
6.5X55 Swede (2 different rifles, both scoped)
6.8 SPC (2 different rifles both scoped)
270 Winchester. 5 different rifles 2 of which had iron sights only)
7X57 scoped
7MM Weatherby Mag Scoped
300 Savage (2 different rifles both with iron sights only)
308 Winchester (3 different rifles 1 with irons and 2 scoped)
30-06 (2 different rifles, Iron sights only)
30/378 Weatherby Scoped
303 British (Iron sights)
8X57 scoped and irons
357 mag (3 handguns all stock with factory iron sights)
35 Remington (with iron sights)
9.3X57 iron sights
9.3X74R Ruger #1 Scoped
375H&H Scoped
44 magnum carbine with iron sights
44 mag handguns (4 of them, all with only factory sights)
50 Cal flintlock
62 Cal flintlock
Laminated long bow with wood arrows.
I enjoyed all my hunts and the ones I feel the best about were those I got at close ranges with iron sights.
But no matter what you bring, remember it's about YOU not your gun.
I say again: Bring what you shoot best

A 270 Win via an older M700 ADL in a first gen B&C LW take off and 130 gr Hornady American Whitetail...
