The reason he used the fireball case was it's short O.A.L. was correct for his needs. The 300 Whisper was designed at the request of Col. Charles Beckwith to develop a suppressed 30 cal platform for the Colt XM-180/CAR-15 capable of delivering heavier bullets subsonic but still 250yds capable and still utilize standard m-16 magazines.
They are still in a weapons locker on Bragg. I have had the pleasure of firing one of those first 50 in both suppressed and supersonic format. Due to the lighter bullets used, recoil is minimal. The suppressed format would keep a 3rd burst in the triangle at 50yds when the more experienced shooter used it. I could keep three in the head zone. First time I had seen a red dot sight too. An early C-More.
Then it was the 460 Weatherby based 500 Whisper, but that's another story.

I remember seeing 300 Whisper tables showing that the 240 HPBT Match King starting subsonic was still running 900 FPS at 200 yards.

And remains head shot accurate to that range in the excellent SSK built carbines. I get good accuracy from the 300blk with with the same bullet. But the original CAR platform and short neck whisper design held subsonic loads to a 168gr bullet. Supersonic format was a 135gr.

I have a custom XP100 done by Gary Reeder in 358 Winchester. It is dead accurate.

I have a custom XP100 done by Gary Reeder in 358 Winchester. It is dead accurate. ***** John Towle brought two of his XP’s to the first IHMSA Internationals in 1977. one in a shortened .458, the other in .358 Winchester. As I didn’t have an unlimited pistol, Towle loaned me his .358. Douglas 11-inch barrel, 4 cuts of Mag-na-Port, blade front sight, Micro or Bo-Mar rear sight. Fiberglass (center-grip configuration) double-pistol grip stock by wildman canoe maker Jimmy Gilman, another New Hampshire crazy. The gun was designed to shoot prone, and I hadn’t even finished the 15 chickens (the first IHMSA championship was 60 rounds per category, which changed to 80 rounds per in 1978), when the forward pistol grip ripped off in recoil. Loads were a John Towle Rocks & Dynamite concoction, Hornady 200 grain Round Nose for chicken, pig, turkey, Hornady 250’s for the ram. David Bradshaw

In the days we thought we were invincible. Made it through that with my wrist bones intact. Had a local IHMSA shooter with one of the shortened 458 wrist killers. He was a small man and short Creedmoor. Was told it would literally move him across the ground.

Early 80's got slotted between Mike Franklin from Ohio and his traveling partner Frank --- also from Ohio at Lawrenceburg Ky once. Mike was shooting his Towle built 350-338 and Frank a 7-57 both ported. The firing positions were close and off a 3 inch tall platform laid on the uncovered concrete line. Had to try to time my shots between theirs, as the blast was severe from both sides, and would push me and my 10 in 30-30 clean off targets.
