17 Remington Fireball – a Remington Model 700 SPS Varmint with heavy 26-inch barrel (1:9 twist). The Nosler bullet shot best throttled back to 3,365 fps, though juggling the seating depth on this relatively short bullet might improve accuracy with heavier charges.ĬFE BLK paired especially well with the. With the 15.5 NTX, velocity hit nearly 3,850 feet per second (fps) with a maximum load of 13 grains, though accuracy was best using 12.5 grains at 3,689 fps, which fairly matches the A-1680 and Hornady factory loads velocity-wise. The exceptions were Hornady’s 15.5-grain NTX, as I was curious to see how much velocity could be developed with the flyweight nontoxic bullet, and the 20-grain Nosler Varmageddon, in seeking a more affordable alternative to the V-MAX for high-volume shooting. Twelve grains of Accurate 1680 beneath Hornady’s 20-grain V-MAX shoots super-tight groups at factory ammunition velocities, so I’ve never really been inclined to experiment further. I fell into a super-accurate load right out of the gate while attempting to duplicate Hornady factory ammunition, which shot remarkably when the rifle was new and I was accumulating handloading brass. 17 Hornet, chambered in Savage’s affordable 25 Walking Varminter with a medium-weight 22-inch barrel with a 1:9 twist, is perhaps my favorite varmint rifle, so it consumes hundreds of rounds each spring. While generally accurate, the thin barrel warms quickly. 221 Remington Fireball is a rechambered Remington Modelħ88 Remington. 300 AAC Blackout (10-5-inch-tubed “pistol”) and very limited auditioning with a 7.62x39mm Soviet (short-barreled bolt rifle). My experiences involve the 6.8 Remington SPC (my nighttime thermal-imaging hog rifle) and. Unsurprisingly, CFE BLK is exceptionally compatible with various gas guns, as it was designed specifically for the. The rifle wasn’t a tack driver, but was fun to shoot. 218 Bee used to develop these loads was made in 1947, a Winchester ModelĤ3 Special with a somewhat weak mid-bolt lug. So it is no surprise that CFE BLK also pairs superbly with the necked-down. This powder provides top velocities in the Fireball, combined with lower chamber pressures than favorites like Alliant Reloder 7, Accurate 1680 and Hodgdon 4198. Certain powders seem custom made for specific cartridges and CFE BLK is the “magic dust” for the. This experiment impressed me enough to have another Fireball rifle built, this one carrying a heavier stainless steel barrel threaded into a smoother Howa 1500 Mini Action. 222 Remington, included a thin 24-inch barrel that had been set back and rethreaded to create a Fireball chamber. The Remington Model 788, originally chambered in. I became an especially ardent CFE BLK fan after acquiring a. I’ve also enjoyed worthwhile results with CFE BLK in an older. 50-inch groups from a Savage Model 25 Walking Varminter rifle, but experiments with CFE BLK turned in worthwhile results that may improve in other rifles. Accurate 1680 has long been my go-to powder for 20-grain Hornady V-MAX bullets, giving me. It has accounted for hundreds of coyotes.ĬFE BLK was a natural choice for my. Model 340 E he has been shooting for about 38 years. 22 Hornet, used to develop the listed loads, is a Savage CFE BLK offered a solution, proving temperature insensitive, ultraclean and developing lower chamber pressures. Still, I was always bothered by the old pistol powders’ dirty nature and tendency to show pressure increases under a hot sun, occasionally requiring a ramrod to remove stuck cases. I’ve long used H-110/Winchester 296 (number 63 and 64 on the relative burn rate chart, CFE BLK number 70) to fuel my Hornet loads, receiving top velocities (2,953 feet per second with a 40-grain V-MAX, for example), from maximum loads providing fairly decent accuracy (usually around. 22 Hornet fan, I glommed onto CFE BLK quickly. It has generally proven extremely accurate.Īs an enduring. A Remington Model 700 SPS Varmint was used to develop the accompanying
