reloading question

sig-man
I am having to use BR-2 large rifle primers on my 22-250 reloads.

I have been putting 39.2 grains of H380 under a 53GR Barnes TSX FB.

The Barnes book says you can go over this charge a little because of the ring lands groves in the bullet.

My question is ,

Do you think I should back off a few tenths of a grain to offset the large rifle primer?

    Does anyone know what the factory load is for
    270 wsm Winchester Supreme loaded with a 130 grain balistic silvertip bullet. I am looking mostly for powder charge and powder type. I have a friend that will reload them for me but I want to stick with the factrory specs because it shoots soooo well.
    Thanks

    Take a look here: http://www.reloadammo.com/300load.htm It's hard to say about reducing the powder charge, since you don't know what the powder of the orig load is.

    You need to get some load data, find out what type of powder is in it, then find out how much you need for whatever type of bullet your using. You have to properly remove the bullet and reseat and crimp the new bullet. Its a process, not just a simple pull with plyers and replace kinda thing.Its not as easy as you think if you wanna be safe about it.I'd leave those cartridges alone.If you have to much or not enough powder you can really mess something up.Be safe, not stupid.If your interested in getting into handloading you need to find some books on it. There are many reloading manuals, just about every bullet manufacterer has one.

    Assuming that you can SAFELY replace the bullet. you should get slightly less MV - not a significant change.

    Safest course of action would be to shoot the rounds you have now & start from scratch w/ a known powder and the 180gr.

    Please tell us that you are not serious about loading that way. First of all you need a loading press,then you need dies, I think you said 300 win mag,whatever it is you need dies for that particular cartride. Now you need a powder measure,scale and a powder dribbler. Next you need a quality set of dial calipers,priming tool,case trimmer and a reputable loading manual. you will need to buy primers,powder and bullets. First you need empty brass so go shoot what you have and save the cases. You may also want a case tumbler to clean them but I'll tell you now and especially in magnum cases tumbling shortens case life. After you have some empty brass you will need to resize and knock out the old primer on all the cases. Get out your sizing die and set it up the way your loading manual tells you. Now get a can of case lube and spray down the cases( I prefer ONE SHOT). After the lube sets up you can now resize the cases,the primer will come out at the same time. Now look in your loading manual and on the first page of you cartridge you will a picture of the case,see the measurment from the base to the neck? Get you dial calipers and measure each and everyone of the cases, all cases that are long set them aside. After you are done measuring them now you need to set up you case trimmer,follow the instuctions included with it!!!! Now that you have a set of sized and trimmed cases it is time to "fill 'em up". Get out you priming tool and follow the directions on priming them. When you are done with that you will need your powder measure ,scale and dribbler. Now hopefully after consulting the person at the sporting goods store and making a powder selection and bullet section you have refered to your loading bible and determined how hot to load them,word to the wise ,,start at the lowest charge and load five,increase charge by 1/2 to 1 grain and load five more and continue till you either find a load that works or you reach max.Ok now lets load the cases,you probably have an IMR powder so you WILL NEED THE DRIBBLER! IMR powders and others like it will NOT consistantly measure so measure each one on the scale and dribble to desired charge. Now that you have all the cases charged it is time to seat the bullets.GO SLOW WITH THIS BECAUSE A BULLET SEATED TOO DEEP OR TOO LONG WILL INCREASE PRESSURE AND RUIN YOUR WHOLE DAY! Seat the bullets to the specified C.O.L in the manual for you particular bullet,pay attention to what the bullet is classified as and adjust the seating die a little at a time untill you reach desired depth. If you want total accuracy I suggest seating the a bullet in a dummy case long and then chamber the case in the gun,if the bolt closes hard remove the case and give the seating die 1/2 turn and repeat untill the bolt closes easily,also use a marker on the bullet to watch for contact with the rifeling. Please read the manual front to back and if you have any questions consult you locall sporting goods clerk or someone who is knowledable about reloading. reloading is not easy and can be boring and frustrating. It should be taken very serious as one mistake can cost you your gun at the very least and maybe your life. Loading can have an inital investment that can scare most people from it and if one powder don't do what you want you have to buy more and at $20 a can it can get quite expensive. Godd luck and BE CAREFULL!

    PLEASE go buy a reloading manual.PLEASE read & follow the directions.PLEASE respect the safety of yourself & those around you when you load your own reloaded ammunition AND when you take it to the range to use. It only takes ONE mistake to ruin EVERYBODY'S days from then on.

    First let me say that I have been reloading for almost twenty years, I have all the stuff I need to do it safely, A buddy got some match ammo from some seal team guys loaded for their stuff, they shoot real tight groups, but are of bullet type not condusive to killing deer, He wants to put the 180 grain ballistic tips on the same powder ,casing everything, pull the bullets with kinetic hammer the whole nine yards,he just wanted to know if by reducing the bullet weight with the same powder load if it would increase or decrease the velocity...

    As a rule of thumb. Lighter bullet with the same powder charge will less pressure. I don't have any data in my Hercules load charts for a 190 gr 300 Win Mag. I goes from 180 gr to 200 gr.180 gr with 76.9 gr of Hercules Reloader 22will give you 3,030 fps @ 60,000 psi.200 gr with 73.4 gr of Reloader 22 will give you 2875 fps @ 60,000 psi.So since your going from a heavier to a lighter bullet you will acutally have a reduced charge for the 180. However this would be based on the fact both bullets were of the same type ie. SpitzerOk I'm ready for all you reloaders to attack.
