[QUOTE="Swamplord, post: 763899, member: 2460"] I have the dimensions for my 7.62 PRO that you can go off in the attached pics... I have the "PRO" (Precision Rifled Ordnance ) series of wildcats I have been working on for my Sako M995 switchbarrel rifle and have 2 wildcats based on the 300 Norma Mag case 6.5 Prometheus 7.62 PRO based on the 338 Norma Mag case I have the 338 PRO 375 PRO 416 PRO 458 PRO There will be 7 barrels total for the project based on a Sako M995 and a KRG Whiskey 3 chassis, topped off with a Vortex PST 4-16X50 EBRMOA scope the 1st barrel is already on the finished rifle and is chambered in 338 Norma Magnum I also still have the original bbl the rifle came with chambered in 7.82 Warbird and can use it if need be, making 8 total barrels in one rifle system ! The design of the cartridges and chambers was specifically intended to be run in rifles equipped with AICS cip length detachable magazines . the throat/leade is set so the bullets do not protrude below the neck to enhance powder capacity, at the same time the neck was made longer and shoulder pushed up to 35 degrees but top of body was not increased in diameter but kept at .570", which I found feeds and cycles from the mags much better than a blown out AI 40 degree version which occasionally tends to bind up and jam in the mag due to the steeper shoulder and slightly larger top of body diameter without providing a usable increase in powder capacity ! You will notice the neck lengths are longer in the 6.5 and 7.62, the longer necks are for the cartridges that are more susceptible to faster throat erosion the 338, 375 and 416 share the same .342" neck length and the 458 has a .375" long neck to hold the long heavy bullets, which is important in a hard recoiling dangerous game rifle. If the Rem 700 will not work out for my 500 Jeffery based wildcats, they will be built on a similar platform off the Sako M995 currently in 30-378 WBY, I will just have to modify the ridges in the mags to accept the wider case body, the cartridge oal will remain the same for all reg. hunting bullets up to 300 grs. and 330 gr- 350 gr. long high bc bullets will be run single shot for long range shooting. I designed and own all the reamers and they are proprietary, made for me by PT&G Dave Kiff is a fantastic and very knowledgable gentleman who has assisted me in the dimensions and developement of my reamers, without his help none of these wildcats would be here today ! Neil Jones is making me the dies, with all the crazyness going on he is super busy and ETA is not known at the moment... ........ [/QUOTE]
