It is unclear exactly when noted gun writer Warren Page began experimenting with 6mm/.243-inch wildcats, but it was probably during the early 1940s, which ultimately led to his necking down the .308 Winchester case shortly after it was introduced in 1952. Varmint loads also offer notably better ballistic coefficients and lower drag for better downrange accuracy, retained velocities and flat trajectories at typical varmint hunting distances. Two of the most common mistakes when assembling .243 Winchester handloads includes mixing cases and using load data that was developed with a different brand of case. Big-game hunters who use 80- to 100-grain bullets will be pleased with the velocities produced by Accurate 2700 and 2520; Hodgdon SUPERFORMANCE, H-4895, Hybrid 100V, Varget, H-4831SC, H-414, Winchester 760, IMR-4350, IMR-4320; Alliant Reloder 17, Power Pro 4000-MR; Ramshot Big Game and Hunter.

Six major concealed carry insurance programs are now available to the millions of Americans who carry concealed. 223 Win. Silver $$ Contributor . In working with the .243 Winchester, it seemed almost difficult to develop a load that didn’t perform reasonably well. 2 contour Douglas barrel; it proved capable of 1⁄4-MOA accuracy, which was uncommon for that era using common hunting bullets.

Anyone have any load's for reloader 25 for 243 win? This site uses Akismet to reduce spam. Open up the load data page you wish to download. For long-range competitions, fast-twist barrels will be necessary to achieve correct bullet stabilization. Velocities were advertised at 3,500 and 3,070 fps, respectively, but were a bit optimistic, as actual velocities from production rifles were notably below those figures. We obtained ¾-inch groups at 50 yards — better than the other, slower burning powders — and yet the velocities were on par, running at 2,165 fps. Pet Loads and Handloader are registered trademarks of Wolfe Publishing Company. It makes a great choice for both the .22-250 Remington and the .220 Swift, taking advantage of the case capacity, and generating respectable velocities in the pair of varmint classics.

Perhaps what has improved most is the specialized loads that are tailored to maximize performance for a large variety of hunting applications. Alliant gives load data for the .270 Winchester, .280 Remington and .35 Whelen, in addition to the .30-’06 parent case, and though RL-15 is on the faster end of the spectrum for those cases, it will work, and work well. RCBS dies were used to develop the accompanying handloads. Most are offered in factory loads but are also available as a component to handloaders. It’s in the bigger cases that I recently found Reloder 15 to be a huge help, as my pal Mike McNulty and I prepared for our safari to Zimbabwe. Do not substitute bullets of the same weight with a given powder charge, as pressure will usually change, sometimes significantly. reloader 25 for 243 win. Rodney.

Load Data &Technical Information by Caliber. Case capacities have been found to vary by over 4.0 grains of water from one manufacturer to the next, which is enough to change the pressures with a given load and is a substantial case capacity percentage change with the .243’s modest powder charge weights. 257 Roberts. Two good Cape buffalo bulls fell quickly to the Peregrine/Sledgehammer combination, despite the 112-degree Zimbabwean heat.

260 Rem. Without boring you with all the data, 88.0 grains of RL-15 gave me 1¾-inch pairs, with the velocity matching the Hornady load within 15 fps and a velocity spread of 8 fps. It’s also a great all-around choice for the .375 H&H for all bullet weights, giving a good blend of velocity and manageable recoil, as well as low pressure for the African heat.

Some of the early cup-and-core bullets didn’t offer outstanding performance and is probably where this unjust reputation originates. 243 Win. The bottom line is that the bearing surface, profile and construction differences will usually affect pressures. Silver $$ Contributor. Comparing these cartridges with the H4831SC loads — which gave more than acceptable results — the felt recoil again dropped off considerably, while I easily made the target velocity of 2,160 fps. 223 Rem.

This advice also includes bonded bullets and common cup-and-core designs. On the far ends of the spectrum, RL-15 is a good choice for the diminutive .17 Remington, as well as the .375 H&H Magnum, .416 Remington Magnum and .458 Lott; it’s a stellar choice for the .416 Rem. The pairs of bullets — one each from each barrel — would tell the tale of what my double preferred, as they would probably start out low and wide at the bottom end of the spectrum, rise and come together as the rifle showed what it prefers, and finally rise higher and separate as velocities continue to increase.

The same principal applied to my .470 NE, though the loading process is a bit different for a double rifle than for any single barrel rifle. Nosing through the Woodleigh Bullets Reloading Manual — a volume that any reloader of big game cartridges should definitely have in his or her collection — I noticed there was a listing for RL-15, between 102.0 and 104.0 grains to achieve the classic velocity of 2,150 fps.

Any experience? In other words, if a load was developed in a Norma case that holds 56.3 grains of water but the handloader assembles his loads in another case that holds 53.3 grains of water, pressures can jump significantly. Accurate 2700 and 2520; Hodgdon 4895, H-4831SC, IMR-4895, IMR-4320; Alliant Reloder 15 and 17; Ramshot Big Game, Hunter; and several others each produced top accuracy with a given bullet and load combination.
