Will it shoot? You bet! Marking has evolved. My S&W AR and Dillon conversion are marked Whisper AND Blackout.

Very nice! What is the barrel twist rate and length?

7 Twist, 15 inch, Shilen stainless Excellent! That will stabilize the 240 gr. SMK

Great candidate for a suppressed hunting pistol

The original intent was to thread the muzzle. The friend who built the gun had an ATF phobia and did not want to thread it. When we built this thing, in the mid 90s, you didn't see all the supersonic loads we now see for the 300 Whisper/BO.

The 240 SMK is accurate to at least 1,000 yard when fired subsonic with a fast twist barrel, which you have

Stan.... looks like an H-S Precision Fiberthane centergrip stock with aluminum bedding block. If so, I’ve never seen finish so slick on an H-S handle. When H-S made a Fiberthane centergrip for the XP-100, I put one on a 7mm Remington BR with chamber cleaned up to 7mm IHMSA/BR. The 7mm IHMSA wears its parent .300 Savage body taper; chambering it to 7mm IHMSA leaves a ring. A straighter reamer removes the ring. Contrary to writing which declared the aluminum bedding block hurt accuracy, that only epoxy tightened groups, my experience revealed astounding, consistent accuracy. I used both action screws, the rear screw not really snugged. The barrel is full float all the way.
In contrast, I did not use a rear action screw on George Petersen’s walnut center grips (Western Gunstock of Aptos, California). `
As John Parker points out, the .300 Whisper is JD Jones adaptation of the .30/.223 to heavy Sierra match bullets through fast twist. it is properly called the Whisper. Reckon to call it any other name amounts to theft. David Bradshaw

David... You called the stock. A buddy of mine had it painted 20 years ago. Bought two of them. The other ended up as a fast twist 6x47 (the original 222 Mag case open up to 6mm) built for the 1987 Masters.

Wes Ugalde of Fallon, Nevada built XP-100 Unlimited pistols in 6mm/223 in 1977, the first year of IHMSA. There were folk in the rifle community who claimed a 6mm built on the .223 or .222 Rem Mag case wouldn’t shoot, a claim which somehow went over the heads of steel shooters. The challenge for a 6mm in silhouette was not accuracy, but momentum. As long as the 200 meter ram was set full-foot on the rail, loads which lacked momentum would leave hit targets standing. Once the overhang rule was adopted, cartridges such as 6mm’s and .357’s were enabled to topple rams with greater consistency. Dvid Bradshaw

I have a Hart rifle in 6x47 Ackley and the only issues I've had are poor quality Nosler 222 brass and finding dies, because every search is muddled with results for 6x47 Lapua In an XP, the round would have been a great choice for the day. Today many would build a 6-204 Ruger instead, an equally good round.

We saw pretty much the same thing in 100 yard NRA Hunter's pistol. Some shooters would shoot 22 MAg and 22 LR in big bore and routinely loose targets that failed to fall with hits low in the body of the target. The 270 REN, 32-20, and the 32 Mag knocked them down but required reloading skills. We could skip our 158 grain 357 bullets off the ground, hit the ram in the foot and it would go.

Nice xp. I only have one. A very early .221 fireball. More accurate than I can shoot.
Didn't someone offer a conversion to a 30/221fb wildcat 30 some years ago? I think it may have been SSK, but can't remember. I was more into the Contender back when I could save enough for a barrel or two a year, but it would have been a while to save up for a whole gun.

I was more into the Contender back when I could save enough for a barrel or two a year, but it would have been a while to save up for a whole gun. ***** You put your finger on JD’s . 300 Whisper----it is Remington’s .221 Fireball necked up to .308. Reckon I fell outta bed on the wrong side, or taken a ride around New Orleans with Dr. John. JD Jones was present in 1978 when this shooter set the 80x80 Record. Prior to my taking the line, JD sent his sidekick to the firing line with a stock XP-100 .221 Fireball to shoot Production. A bunch of silhouetters, along with JD from Ohio, were using the only bolt action allowed in Production category competition. In fact, the Production----in the jargon of silhouetters also called “single shot” category, although it includes stock auto pistols as well as single shots----was configured to include the original XP-100 with barrel just over 10-1/2”. To milk momentum from the slow-twist barrel, steel shooters loaded the Speer 70-grain semi-spitzer. Believe sidekick’s first shot froze the bolt. JD beat the handle open with a block of wood. The .221 case had brazed the boltface and interior of the receiver ring. Proving the extraordinary strength of Remington’s action. JD may not have been thinking “silhouette" when he concocted the .30/.221 but, his experience with the .221 in silhouette had made a nest in his skull. David Bradshaw

Dvid Bradshaw David, I learned something as i believed the 300 Whisper was based on the 223 case. I didn't realize that JD Jones based it off of the Fireball case
