I just bought some cci br primers and am going to use them instead of the mag primers i bought
I much to my dismay found that my digi caliper was off by as much as .05 being i want to work up hot loads you can see how there could be a problem, so i had to dismantle all my rounds in my .270 winchester and am waiting for the rcbs fiberglass dial caliper to arrive, im also thinking about switching for my lee dies to rcbs dies but keep my lee press, I use winchester brass and 150gr hornady sst bullets, im going to get rcbs flash hole deburring tool, and im using reloader 22 powder.
if any one has any exp with this cal. please give me advice it would be greatly appreciated!!!.
Thank you very much
Jerry M.

So is the problem that you are not sure of your seating depth and are afraid that you are loading into the lands?
What load and to what OAL did you load them to?

What rifle are you using? And when you say loading hot what kinda velocity are you after? Are you looking at hornady loading data? Have you looked at Sierra and some others? Finally are you loading for accuracy or effect?

im sorry i should of been more specific, im half asleep..lol..i was wondering if those br primers are good, what kinda products do you all use?. dont recall the depth exactly what i did was, take an powderless cartridge with the bullet sticking way out and let the lands push it in, i figured this would give me a good measurement. then id exp. with how far off the lands id seat em..... what process do you all use if I may ask?
Im really tired so if any of these seems confusing its not you its me..lol..
Like always guys i appreciate your helping me

56.5 is as hot as my nosler #6 says you can go which is in the 2900fps area.
my 2nd ed. lee manual shows 58.5gr of r-22 for 3010fps just remember unless your max oal is shorter than your magazine box you will only be able to shoot one at a time, magzine box is your max oal otherwise. br primers vs regular, i really didnt notice much in performance, but they do seem to burn cleaner.

That should be no problem. Look at Sierra and IMR 4350. They have accuracy loads right where you are looking and their not hot. 3000 isn't too fast, you can get 32 to 3300 and be well in the zone. But make sure your rifle is atleast up to standard.

Wow! I'm certainly not a reloading expert, but that is short mag/ .270 wby range. Seems plenty warm to me. Makes me wonder what kind of velocities I'll be able to get with 150's in my wsm.

This website has a lot of info on measuring devices
I wound up with that Brown & Sharpe. Go down to the bottom and go to page 11 for comparisons.
As far a BR primers, they will not be as hot as magnum primers and in my tests on my guns the Fed215 primers have always provided the best accuracy, especially with a slow burner like RL22.

i have 4 maunals and checked hodgdons web site and reloadersnest and i cannot find anything showing any 270 running 3200-3300fps with a 150gr bullet, im looking at the pressures in my lee manual and to get that bullet to that speed your looking at probably close to 65000psi. |

unless you are hunting for elk or larger game 150gr. bullets are large for caliber. and do not push the envelope/pressure/velocity. it will not make an iota of difference....

I am far from expert myself, but seriously! The rifle I am building will handle a good range of "Hot" loads, but I don't plan to exceed 3600. I do recall the Sierra manual offering loads in the 3200 range but since I share the manual I don't have it with me today. That is likely top end of what they will list, but having talked with some of their loading experts the manual is going to be kept in check. As most loaders know we just have to watch for signs of excessive pressure in primer and case deformation. He may have to drop to 140gr. to get the load he wants.

Throw Mitutoyo into that, also. Both are very well made and use hardened components on calipers and mics.
I have not seen Chinese made mics hold up. Some of our apprentices buy them, the threads wear out and they become useless. Like was already said, buy once.............

Mitutoyo makes good stuff. I think with all the stuff going on, supporting the American Tool and Die industry makes sence.

in all of my books you cannot get to 3200 with the .270 without shooting a 110gr bullets or lighter, and even with the 100gr bullet you wont hit 3600, you will get 3400-3500 if you load up a 90gr bullet you can get 3600 though. i wouldnt trust any book that says you can get 3200 with a 150gr, cause you cant even do that with the .270wsm or .270wby and they both have bigger cases. i think your asking for disaster myself. watch your pressure signs and work it up slow otherwise |

Finally a subject I have some experience with. Not reloading, but precision measuring tools. While the Mitutoyo are pretty good, they are not a Starret. A machinist lives on his calipers, and mics, and I see more Starret than anything else. Very good for the money. Nothing wrong with the Mitu, I just think my Starrets are a bit more accurate from one day to the next than my old Mitutoyo. I realize we are not making space shuttle pieces, but handloads should be looked at as potentially fatal if something goes wrong.
