Need some info/advice

[fratri]

I am relatively new to reloading, I have reloaded my .223 for a couple years now with good results, mind you I probably only load a couple hundred a year....so with some experience behind me I thought I would try and load some of my spent WIN .270 casings. I picked up some lee dies, some powder, primers and some Hornady BTSP 140 gr bullets. COL is 3.28 but if I leave it at that length the ring/groove around the bullet is exposed, my question does that matter?

I included a picture to help explain my post.... Thanks for the help in advance

my 2 beans ... NOT OKAY.

The edge of the shell should be sitting in the middle of cannelure (bullet groove as you call it) and then crimped.

Hornaby's 8th edition (reloading manual) for 270 winchester states COL is to be 3.210" for 140 gr BTSP bullets ... you may want to confirm the COL you stated.

Just curious .. have you checked to see if that combination fits your mag and chambers OK.

Just ignore the groove, cannalure, in the bullet.
You don't have to crimp, so seat your bullets to the depth you have calculated as being correct.
Also, don't get hung up on what the loading book told you was the over all length. The loaded cartridges should fit your rifle. If that load clears the lands, and will still work through the magazine, it should be about ideal.

Thanks H4831, I read one of your other reloading posts regarding how we are robots when we learn to do only what the manual states...Liked your thought on the process...Need to be a little more of a thinker, not too much more....Thanks for the help, thats what I thought just wasn't sure.

The reason for crimping as stated by Hornaby " Recoil can jar bullets loose from their original seating if they are not correctly and sufficiently crimped in place to resist such movements". Like it says .. can, meaning it may or may not.

Many of us never crimp for use in rifles fed by a box mag. The only places where crimping becomes really important are for use in tube mag fed rifles such as most lever actions and for revolvers. I have never had a problem with just using neck tension to hold bullets in place, including with my Garand.

Bah!

Don't even bother with the cannelure. If the cartride cycles, chambers, and most importantly groups, have at'r.

Hornady's trying to sell you an unnesecesary concept. Not many other vendors (speer / nosler / sierra etc) even bother on most of their product lines.

Your correct in stating that Hornaby tends to sole it self out with cannelures on this caliber (and many others). Personally I would go with ones that don't cannelure, but he asked about hornaby (a specific bullet) and would hesitate to say what was presented is good to go. It's their bullets and my comments were from the that manufacturer's most recent publications ... I would be a fool to suggest otherwise.

In reality they may be fine .. but I would hesitate to give advice outside of the manfacturers recommendations /// for to do so would/could result in assuming any and all responsibility.

explorin2, advice outside the bounds of Mfg. specs goes on in reloading all day long ! There are sites and programs practically devoted to it.

I'm not educated in the law, but I nonetheless doubt that someone could be held liable for merely expressing an opinion,,, for free.

I'm guessing you just starting loading for one..maybe two calibres, own one manual, and a starter kit.

Hornaby?

I'm no legal myself expert by far, but advice and opinions are two different things. All I wish to express is that it is my opinion that manufacturers recommendations are what need to be followed (sure there is the acception). To provide a statement outside manufacturers recommendations is risky in my opinion, for it presents an opportunity for mishap ... and I don't want to be a part of hishap!!

Alot of novice reloaders come to this site/forum with questions, and for me it is these people that need to know the "manufacturer" is the best person to answer questions on thier equipment. Some responces push the boudaries of safety and common sense.

Oh .. and I have used this site for advice and opinions with troubleshooting with great success.

As said many times before. Ignore the cannelure. Seat to achieve suggested OAL or if you're loading for accuracy, check out threads about seating bullets close to the lands. This completely ignores OAL AND CANNELURE. What works well for one rifle, may or may not for another.

Thank you for all the help. loaded about a dozen rounds with a couple different wieghts and will check them out for accuracy when time permits, thanks again...
