[QUOTE="Coercionist, post: 2627767, member: 120676"] I have also thought about shortening a snipetac. Im looking to rid the case of wasted space (maybe prevent the rumored hang fires) and mag feed the heavy bullets up to the 400gr MTH/Lazer (2.209” and 2.290” respectively) and the heavy hammer bullets: 395gr @ 2.180” and maybe, but it’s pushing it, the 411gr @ 2.300”. With shortening the body .150” you said the long 361gr @ 2.200” was just short of your max mag OAL so I may shorten the case by ~.175” also were you using the standard cheytac mags or the new slightly longer cadex mags? If you were using the older mags then a new COAL would be allowed at 4.625” and I dont think id have to shorten the case much more. About the ballistics- you said that shortening the body gained velocity over the standard snipetac. Did you mean to say standard cheytac or was there an actual velocity increase as you shortened the case. I guess it makes sense if you use the same amount of powder and cut down the case, therefore increasing pressure. Do you recall any of the numbers? Actual velocity, barrel length, any data of 400gr bullets or did you just use the 361gr. Any info you could give would be greatly appreciated [/QUOTE]
