Re: Bullet tip modification

I'm going to set the bullets up to use the mag one way or the other. Removing the tip will let me move the front edge of the bearing surface closer to the lands by the length of the tip I remove. So that isn't really a trade off.

I'm not excited about losing 200 FPS at 600 yards and I am concerned about the consistancy of drilling a hollow point. This alone might cause me to simply remove the lead tip and leave the end of the bullet flat. I will have to think about that.

As far as the dust concern goes, I will be either drilling the tips or facing them on a lathe type set up. If my kids are going to ingest or inhale the lead they will have to chew it first. In other words I wont have filings or dust. It will come off in chips. So we are good there. A quick sweep up and all is well.

Thanks for all the input. It is certainly giving me lots to think about.

Re: Bullet tip modification

I figured that the lead melting thing was BS.
What type of action are you using ? you may be able to get a new longer mag box of have your existing one lengthined

Re: Bullet tip modification

Hi i am using my 7mm A Max bullets up for hunting in a 7mm SAUM and i get my Meplate uniformer and trim the tip off then i drill the plastic pin out of the centre they shoot well and i can seat them out to give me more capacity in the case and get the boat tail junction above the doghnut. You can get a Meplate trimmer from Kevin Cram afetr you trim of the lead level with the jacket you can use the internal deburer to hollow point your bullet the projectiles are verry uniform as the tools are for triming match bullets to have the same length so triming the lead of a huntiung bullet is easy and accurate . David tubb also makes one without the centre tool so you can flat point them using a batery drill we have also trimed Military FMJ bullets to just show lead then they can be shot on ranges where FMJ bullets are not able to be shot it also makes them expand and work like a soft point for hunting game like goats and pigs.

Re: Bullet tip modification

Hey guys. Good news. I assumed that the factory chamber in my brothers .338 (and my nephews .243) was long like my .308. All 3 guns are Rem 700s. Mine is a VLS heavy. In my .308 I can't load to mag length and get anywhere near the lands. I was wrong, man was I wrong. I was prepping brass this evening and decided to try the "Bullet in a fired case" method of determining the COL. Well I got VERY consistant results this way and I also have PLENTY of room when putting these rounds in the mag. I won't worry any more about trimming the lead tips. If my brother has any concerns about deformed tips then he will just have to be careful with them. [img]/ubbthreads/images/graemlins/smile.gif[/img]

We can keep the high BC. We can keep the same terminal expansion. We can keep the same Sierra consistancy. And we can leave behind the nonsence associated with trying to accuately modify 100 bullets. [img]/ubbthreads/images/graemlins/cool.gif[/img]

Isn't that funny. I could have saved this concern if I had tried the chamber first. Oh well, another lesson learned. I just wish my .308 was chambered like this. [img]/ubbthreads/images/graemlins/wink.gif[/img]
