Overall length what is too long?

New to reloading and not too sure what's too long for overall case length? I've read about guys being .005 off lands in a rifle, but I hate to say how do you know when to stay at factory length? I'm getting ready to load my first 7mm and 300 magnum loads.


Thanks in advance.

Re: Overall length what is too long?

Congrats on getting into it you will have some fun. There are a couple of answers to your question so i hope i don't confuse things. First what are you looking to be able to do? If you want to be able to feed from a magazine you will have to limit the oal to something just under the internal dimensions of the mag. If you don't care about being able to feed from a mag the oal is much less relevant as there is not real outer limit so long as the bullet is held in the case neck. You can play with into the lands touching the lands and off of the lands in various increments till you find what your gun likes. Some mags or calibers it wont make a difference ie you can seat a bullet very long to be able to get you into the lands of your barrel and still be able to feed from your mags other calibers and rifle setups that are mag fed will almost ensure that you will have some level of jump to the lands. I often find most of my best loads are into the lands with Long Range VLD style bullets BUT NOT ALWAYS and i have also found other accuracy nodes that worked with a lot of jump. I know some who shoot short action rounds in a long action just so that they can use the mag. If its a true long range gun you likely arent giving up much having your OAL turn your gun effectively into a single shot due to oal. in LR my opinion is that accuracy and finding the best load is more important than saving a second on the reload. if you're shooting 1000yds and your first hit is off throwing another round downrange without other adjustments is not wise so again a second isn't going to change much.
Sinclair sells a great tool that will show you how to get to the lands touching then take that oal and add or subtract length off of that with your seater die to start experimenting. also to be more precise use a comparator to measure bullet OAL as the tips on many bullets vary enough to make a difference and measuring length off the ogive will give you better and more repeatable results.
Hope this helps as a starting point.

Re: Overall length what is too long?

also since i likely took that further than you asked factory length really means nothing other that it will feed from virtually all mags but i can usually always seat bullets further out than sammi spec and not induce feed issues. It can be a safe place to start but technically doesn't really mean much as each rifle setup is unique. starting there may be a great OAL accuracy node but it could also be a place your rifle hates.

Re: Overall length what is too long?

The tool on the Sinclair website is it a oal gauge / bullet seating depth tool you mentioned ?

My hope is to reload for LRH in Wyoming with my savage 111 long range hunter in 300 win mag and Remington 700 bdl in 7mm rem mag for my dad. We were both thrown to the wolves as our first shots were 352 yds. That's 152 yds more than we'd ever practiced. But the experience has us both hooked.

I agree! But here is a way to measure your oal for each bullet.
1. resize a brass Donot prime or powder it but lube the inside of the neck
2. place a bullet on the brass and put into the seat die just enough to hold it and no more
3. pointing in a safe direction chamber it, the bullet will seat itself at the lands, now place it back into the seat die with the seat adjust all the way out and screw it down on the bullet
4. measure this then repeat step 3 and screw it down (a 1/8th turn then measure), until you are down 5 or 10 thou off the grooves
5. place this dummy in with the box of bullets for die setup
when I have loaded the 99th out of the box I pull that dummy and load it.
I do this for every package I buy, all of my loads are 5 thou off lands and this method saves me a lot of time with die setup

Re: Overall length what is too long?

If you are fairly new to reloading I would highly recommend getting the "reloading for long range hunting" DVD from Defensive Edge.

Shawn Carlock, owner of Defensive Edge, goes thru everything step by step and does it in a way that is easily understandable. It also helps to actually see things being done as they are talking about it. Being able to put the visual part of learning along with the terminology is very helpful and will only accelerate your learning curve. Nice thing about owning the DVD is you can watch it over and over and as your reloading knowledge grows you'll be surprised at what you will pick up on ever time you watch it.

Re: Overall length what is too long?

Good thread, I'm in the same boat. I was going to buy the one he uses in this clip on amazon for $18.


But after reading this I may just make a dummy round.....

Has anyone used this product?
