I just got a new 270wsm and i reload my shells. r-p 270wsm cases cci primers 140gr imr 4350 powder and 270 cal 140 gr sst leds. Can some one please tell me why my fireing pin is going thru the primers and leaving a hole in them when there are seated all the way>> .. daruse
According to Hodgdon's website, the MAX powder charge is around 58 gr. If that 140 grains isn't a typo, you're lucky to be alive and in one piece right now. www.hodgdon.com
definately not 140grns of powder, it wont fit in the case. peirced primers are typically caused by severely under powered loads. have you fired any factory loaded ammunition in this rifle?
hornady lists 140gr sst's with imr 4350 at 53.4gr minimum, and 58.6gr maximum.

Mr. you'd better either get out of the reloading game and buy factory ammo or buy yourself a darn good reloading manuel and follow it to the letter. You'd best thank the powder god those loads you mention didn't blow up your rifle and you along with it! Fact of the matter is now that your rifle has survived such an overload, take it to a competent gunsmith and have it checked out! I'd be afraid to fire it again even with factory ammo. This is first I've heard of someone loading 140grs. of any smokeless powder and living to tell of it. I don't know, but I don't think the 700 nitro takes anywhere near that much powder and that's the most powerful rifle on the planet.
i got to see a typo but i would go with the manufactures advice and in the fine print you will notice it says starting the load sould be on the low side buy some factory ammo and see if you still have this problem then i would work from there to make shur its not the weapon and pin being to long then work up your load
Glad it was a typo. Get some reloading books from IMR and start with the smallest load and work up. Change primers. Get a tutor. Welcome and be sure that charge is correct every time. One Squib or overcharge WILL ruin your day. Blown gun, bodily injury, hospital, police report, mental evaluation. NOT GOOD. Find some one who reloads.
Never, never, never start with a maximum load. 9X out of ten it isn't the most accurate and it could possably damage your firearm. Start with the lightest recomended load in a good reloading manual and work up in small increments till you find the most accurate load with those components. Then if you want to experment futher. I repeat Never, start reloading with the maximum load!
Make sure your case overall length is within specs. Do you have problems closing the bolt on a live round or opening it after firing? Check to see if your primers are fully seated also.
