[QUOTE=".30US, post: 1227773, member: 19108"] I just received my .25x45 barrel from BHW last week from their sale. I had been wanting a .223-based wildcat for hunting with my AR for a while, and really liked the .20 Practical...except I don't hunt anything it would be ideal for or have any other .204" bullets around, already. I picked up a .257 JDJ Contender barrel late last year with a lot of 85 and 100gr bullets, so I thought I would give the .25x45 a try. My AR upper and handguard just arrived and my dies are in transit. The nice folks at Sharps Rifle Co. did provide the following reloading data: [INDENT] (If necking up once-fired military 5.56 brass, reduce charges by 10 percent and work up) THESE ARE MAXIMUM LOADS! APPROACH WITH CAUTION! Load #1 - CCI 400 small rifle primer and Sierra 70 grain Blitzking .257 bullet, Powder H335 - Maximum load 27.5 grains - expected velocity of 3100 fps (needs a powder drop tube) Load #2 - CCI small rifle primer and Sierra 70 grain Blitzking .257 bullet, Powder A2200 - Maximum load 27 grains - expected velocity 3100 fps Load #3 - CCI 400 small rifle primer and Sierra 75 grain Hollow Pnt .257 bullet, Ramshot X-terminator - Maximum load 27.5.0 grains - expected velocity of 3100 fps (needs a powder drop tube) Load #4 - CCI 400 small rifle primer and Speer HotCor 87 grain .257 bullet, Powder H322 - Maximum load 26.0 grains - expected velocity of 2850 fps Load #5 - CCI 400 small rifle primer and Speer HotCor 87 grain .257 bullet, Powder H335 - Maximum load 28.0 grains - expected velocity of 2900 fps Load #6 - CCI 400 small rifle primer and Speer HotCor 87 grain .257 bullet, Powder Ramshot X-terminator - Maximum load 27.5 grains - expected velocity of 2950 fps Load #7 - CCI 400 small rifle primer and Speer HotCor 87 grain .257 bullet, Powder A2200 - Maximum load 25 grains - expected velocity 2900 fps The Ramshot X-Terminator powder comes the closest of all of the commercial powders we've tested to the velocities achieved with our factory loadings in which we use factory OEM powders. Ramshot X-Terminator and Accurate 2230 are the same powder. With a 20" barrel, 2970 fps velocity with 1704 ft. lbs. of energy. 18" barrel, 2890 fps, 1613 ft. lbs. 16" barrel, 2790 fps, 1504 ft. lbs. The OAL cartridge length is 2.245”. The case length should be 1.760”. Trim to length 1.750”. [/INDENT]I chronographed my .257 JDJ with 85gr Nosler BTs at an average of 2855fps from a 14" barrel, so I'm thinking this should be comparable in a 20" AR for coyotes and hogs. I picked up a pound of Accurate 2200 this weekend, too. I have read that some folks that did a lot of testing on the .25x45 described SRC's reloading data as "optimistic," but we'll see. [/QUOTE]
