I've been using this mold with a Savage Axis7mm-08 rifle. Very accurate but it is difficult to chamber some rounds as the nose on it measures .278~.279" and it makes "hard" contact with the lands and needs to be at .276~.2765" to chamber smoothly. I need to size just the nose down to that dimension so it will not be a problem chambering them. My plan is to make a bullet holder that grips the bullets by the base and twist into a homemade dies that will reduce the noise diameter down to .276". Can anyone offer a suggestion how I can make one--my first thought was to drill out hex nut to 1/4" then using a dowel and sandpaper open it up to .276" with a taper...perhaps someone has a better idea????

I checked out the RCBS 7mm 168 SP-GC mold, which I also have---it's nose measures .276" and fits nicely in the Savage Axis 7mm-08 chamber . I will use it instead and see about trading the RCBS 7mm 145 SIL-GC for a Lyman 287346 or 287405. Perhaps someone might want to do an exchange?

I decided on trying a slightly softer alloy; I made up 3 dummy rounds with it and all chambered in the Savage Axis very nicely. The nose still makes good contact with the lands, but they chambered more easily now. I will shoot a few test rounds later this week to make sure they are accurate. On the RCBS 145 Sil-GC/7mm cast bullet the bullet contact with the lands is a full 2cm; that's 0.78"!

I have been told those NOE nose bushings work to true of the nose but that if you are sizing more than .0005", they start to shave lead.

I have used the RCBS 145gn silly-wet boolit for many years. Yes, the nose is engraved at loading, but not enough to pull it from the case. In my surplus FN mauser it is a very a accurate combination.
