[QUOTE="Fiftydriver, post: 333786, member: 10"] Just to add a bit more to what Ernie has offered. We have been pretty tight lipped about this for several reasons. The design is one that I designed many years ago but never really had the correct application for until Ernie contacted me about wanting an XP chambered for this class of chambering. The real problem to this is the stock holding up simply because the XPs recoil lug is VERY limited in contact area to the stock and generally this small area will break down. On top of that, it is not uncommon not to have the stock crack at the top of the pistol grip with even much smaller chamberings then this. My design uses a full diameter 1.350" diameter barrel shank that has a traditional XP recoil lug in the standard location but it also uses a conventional rifle recoil lug ahead at the front of the full diameter barrel shank. THe barrel is machined and threaded at this location and a custom made stainless steel lock nut is threaded on to hold the forward recoil lug in place. I fully admit that the original idea came from a design that Darrel Holland uses for his V-block rifle design only that he uses an aluminum V-Block with a forward recoil lug but no rear recoil lug. My design uses two recoil lugs which effectively triples the baring surface to the stock for the high recoil energy levels of this type of chambering. Also, I install a pillar just behind the forward recoil lug and thread the barrel to accept a 1/4x28 tpi mounting bolt. The stock is bedded for full contact up to the forward recoil lug and entire receiver. The lock nut is floated as is the barrel from the the nut forward. The regidity of this system is simply amazing compared to conventional bedding and since there is no large aluminum bedding block, there is no problem putting this design in a slim sporter profile stock so weight can be kept down dramatically, as can the dimensions of the handgun. I decided to have the 1.350" shank fluted on the top half to drop a bit of weight as well, plus it just looks good. I have also been working on my new Raptor rifle package. Some of you may remember that project a couple years ago that did not turn out into production rifles but I have decided to start that project up again and have been working on that for the past year and it should hopefully be ready for field testing. The new Raptor will have a new receiver as well as a rifle version of this new barrel design to offer EXTREME rigidty but with very little if any increase in weight over a conventional barrel contour. Anyway, the hold up in accuracy testing has been the wind. Its been blowing around here for nearly the past three weeks over 20 mph. Many days over 40 mph and several over 60 mph. I have never in my 36 years remembered a stretch of windy days like this. Was very hard on hunting and a killer for accuracy testing customer rifles and handguns which are backing up waiting to get on the range. Its supposed to cool down this week so I will hopefully be able to get out and so some long range accuracy testing with Ernies XP very soon. Recoil wise, the 225s barely kick. I know many do not believe that but its true. The 250 gr ABs are not much more but a bit more. Still extremely comfortable. The 300 gr is not uncomfortable but its a noticable jump in recoil but then again, it is a 300 gr SMK at over 2700 fps!!! More to come soon as well on the APS Raptor rifle.
