This thread is the result of numerous phone calls, PM's, emails, and the resulting conversations that have taken place over the fitment of floor metals and magazines from Accuracy International on other actions.
From what I gather the defacto practice right now is to whittle on the lower feed ramp/lug abutment on the receiver.
In my professional opinion this is a DANGEROUS practice to the end user. I base this on the fact that there's already significant material removed from this region due to the necessity of a feed ramp. Additional removal of material is only going to potentially aggravate the situation.
There is a very simple solution: modify the magazine using a little care and a belt sander, file, saw, whatever.
Here is a photograph of exactly what I'm talking about. This is off the Winchester Model 70 control round feed action that I recently used in a 300WM medium weight tac rifle for a client of mine. The magazine box has been altered on the front side. This took less than 5 minutes to do with a belt sander and works perfectly. I've loaded 190 grain bullets in the thing and there's no complication with feeding/function of the gun.
I'm not the smartest guy on the planet and I don't know everything, I do however have a pretty good grasp on what works. The pressures involved with modern centerfire cartridges are not to be taken lightly. I STRONGLY DISAGREE WITH THE PRACTICE OF MACHINING THE FEED RAMP/LOWER LUG ABUTMENT OF ANY ACTION IN ORDER TO FIT A MAGAZINE. Guys like Jerry Stiller, Glen Harris, etc have done the simulations that predict the strain, shear loading, tensile strength, etc of the materials used to produce their product. They are designed to work within those parameters. When a guy goes chewing on stuff he effectively ignores all of that.
It's a very reckless practice.
If this continues its a matter of time before someone blows up an action and a manufacturer spends the next half decade in court trying to convince a jury that a gunsmith took matters into his own hands. Ultimately in our litigious society it won't matter because someone will have to pay because the customer blew his face off. That's the reality of what a jury is going to see/do.
This ultimately hurts all of us because if/when it happens there won't be a Jerry Stiller, Glen Harris, BAT Machine, or anyone else. Lawsuits are ugly and this can easily be avoided.
STOP DOING IT.

C.
