Greg, early on, Ronnie Long and I messed with bullets as light as 95 Gr. - there was no usable gain, but a good deal of doubt regarding bullet "integreity". For the .925" long jackets, shortening the core enough to accommodate a weight of less than 110 Gr. is, in my opinion, risky business - I will not put such bullets in a box with the BIB label! The core length, relative to the jacket length, MUST extend from the base, at least to the tangent point of the nose and shank; accomplishing this with a 7 - 8 ogive bullet is, at best, shakey. In my opinion, we'd need a jacket between .850 and .975 to make 95-100 Gr. bullets - and for what? The BIB 112 features a BC of .32 - a typical 66-68 GR. 6mm will run about .26 -.27 - this means that, regarding wind drift, when the 112 is launched at a mere 2950FPS, it IS every bit the eaqual of a 66-68 Gr. 6mm bullet which exits the muzzle at 3450! Most people are reporting MV in excess of 3050 when using the 112s - a PPC cannot "get there from here"!  A fair number of us are shooting the ten ogive 118s and even the 125s at 3050 FPS; respectively, the BC are : .34 and .36 - run a comparison of THOSE numbers through a ballistics program! ;)

Last spring, I made up a batch of .925 based 112s and pointed them using the ten ogive die - they were a 'no-go'; due to lack of enough shank to be uesful via even the ZERO free bore! They did however shoot great - never mind, that by the time I'd get to the firing line, several of the bullets would have either "squirted' or fallen out of the case necks (the bullet bases were seated less than .0625" into the case necks!) . . . I'd simply  "reinstall" them [via fingers] and shoot!

I shot a couple of prettty decent scores that way - good enough to win at 100Yd on two occasions - but won't be making anymore of them . . . way too stressful! ;)

Having messed about with some of this stuff, it seems to me that the "correct" range of bullet weights for the 30 BR is from 110 through 125 Gr; and for Hunter Class cartridges, up to and including the .30x47 types,  from 110 through about 135 Gr. or so. Bullets in this range offer a very good combination of BC/velocity potential with recoil levels tolerable to most people. And I'll restate: I firmly believe that the .925" jacket (the shortest BR quality jacket available) is unsuitable for anything calling for a core shorter than would be dictated by a finished bullet weight of about 110 Gr.

Keep 'em ON the X! R.G.
