DTIMM I had same thoghts and was going to keep my eye open for one of the bolt guns at gun shows this year. It would not take a lot to do I don't think but I am a gunsmith and can do my own work what other people think is a lot of work is different. What you would need to do is get a good barrel blank that is a barrel of thr right caliber bore that matches the out side conture of barrel on there now then you would need to set up in lath turn down and thread were it gos on action. I should say I always check headspace in the barrel that is on gun and if in good headspace you know what you need for the one you are about to do. After you have threads cut make sure it gos on right. Then you would need to set up and do the chambering. There is a lot of stuff I have left out I am sure I have put a number of barrels on guns it gets easyer all the time seems like if your doing one model of gun more then others.

Thanks Kraiger....was also concerned about using the old receivers, but 7-30 should be in about the same  pressure range...not set up for machine shop but I know some people that are ,gonna do some talking with 'em.

DTIMM It's not just a matter of doing the machine work on the barrel. The person doing the work has to understand why things have to be the way they are for safty reasons. Like headspace if gun is out of headspace it needs to be in headspace when new barrel is put on. It's hard to explain some things with out visual aids and person right there. Who ever you have do work I would be sure they understood things like this. And I would still not want to hotrod and shells I was to put in gun even though it is a bolt action VS lever action.

I loaded some nosler 120 grain ballistic tip bullets shot my doe with this load it was heart lung shot it worked good I think. Brass made from Remington .30-30 new brass Federal 210 primers 40 grains H414 powder. they grouped good I think.

I just loaded some more 120 grain Nosler ballistic tip only used Winchester 748 powder 38.0 grains Hornady book has 38.5 as a max load going to warm up to 36 tomorrow going to go to range see how they work. Will have to get big .50 BMG out also.

Kraiger, are you chronographing your loads?

I normally do but I have not set it up latelly as of the cold and not much time.

I think the shells I loaded with the win. 748 shoot better then the other shells I loaded with the H 414 we had some wind today but I wanted to shoot them and it was not a stiff wind. My .50 BMG shot real good.

I came back to this post as I knew it had the powder burn rate and all the powders listed I have some IMR 5010 powder want to load in my .50 BMG but the only load info. I can find is  H5010 went to see how close the two powders are. And could not find either powder listed in the above burn rate chart unless I missed them it could happen I guess.

I did find the H 5010 powder after looking at my printed sheet but could not find the IMR 5010 any place on any sit. I have a lot of this powder I bought for a cheep price hope to be able to use it for reloading.
