Get more reloads on your .300 Win Mag casings with Peterson's .300 Win Mag – Long. 
If you are a handloader that wants more reloads from your .300 Win Mag casings, then you're going to love Peterson .300 Win Mag - Long casings. 

The regular .300 Win Mag casing Peterson makes is the traditional SAAMI spec’d version that headspaces off the belt. This longer casing version different is different however, as it headspaces off the shoulder.  

Traditional .300 Win Mag casings tend to show signs of case head separation after only 5 to 7 firings. This is because SAAMI specs for any calibre, list a minimum and a maximum tolerance for each dimension on the casing and the rifle’s chamber. With most calibers, the max dimension of the casing for length-to-shoulder (L-T-S) has the shoulder of the casing right up against the chamber wall. 

With a .300 Win Mag, unlike most other calibers, if your rifle’s chamber is cut to the SAAMI minimum for L-T-S, and your casing is at the max length-to-shoulder dimension, the casing shoulder is still .0095” away from the chamber wall. With the same minimum rifle chamber, a casing at nominal L-T-S is .012” away from the chamber wall. In a worst-case scenario, if the casing was produced at the SAAMI minimum L-T-S, and the chamber was cut at the maximum L-T-S dimension, the casing shoulder could be up to .026” away from the chamber wall. This is actually quite a a lot.
That large gap is what causes the casing to stretch so much when it is fired. And it’s that stretching that causes premature case head separation.

These .300 Win Mag- Long casings are made with a longer L-T-S dimension. (All the other dimensions are SAAMI spec.) Its longer L-T-S is what prevents the casing from stretching excessively on the 1st firing. The casing gets more support, which means less stretching and ultimately, a longer case life.

Did the job
Pros: flosser is easy to fill; comes with charging USB wire; nice narrow stream from two separate attachments. Toothbrush feels like a professional cleaning. Cons: must use my own USB wall plug as this didn't come with one; difficult to change flosser heads if you share the unit with a family member; toothbrush is awkward to charge as the bottom has a cap forcing it to lay on side to charge. Otherwise I'm happy with purchase and will keep it.

Water Pic is Awesome
I love both the water pick and the toothbrush. The battery life on both items is really good. the only thing that should be included but isnt, is a cap to cover the mouth pieces when not in use. Unfortunately while I have had no problem recharging the water pick, the toothbrush will not recharge and I been unable to use it since the battery died. Can someone from the company contact to replace the toothbrush. Thank you
