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.

Excellent Strong Bags - Quick-Tie Feature is Genius!
Scent: Unscented, Size: 21 Count (Pack of 1)
These Glad Quick-Tie trash bags have become my go-to garbage bags for the kitchen. I've been through several boxes now and they consistently perform exceptionally well. The quick-tie drawstring closure is the standout feature. Instead of fumbling with traditional bag ties or trying to tie knots that never quite work, I just pull the red drawstring tabs and the bag closes securely in seconds. It's so much faster and cleaner, especially when dealing with heavy or messy loads. The closure stays tight and doesn't come undone during transport to the outdoor bin. Strength is impressive for 30-gallon bags. I regularly fill these to capacity with kitchen waste, food scraps, packaging, and they hold up without tearing or leaking. The plastic feels thick and durable - I haven't had a single tear or puncture even when dealing with sharp edges from cans or rigid packaging. No leaks, no messes on my floor. The 30-gallon size is perfect for my standard kitchen trash can. The bags fit properly without being too loose or too tight, and there's enough material to fold over the rim for a secure fit. When it's time to change the bag, removal is effortless thanks to the quick-tie system. Value is decent - while these aren't the cheapest bags on the market, the convenience and reliability make them worth the slight premium. Not having to deal with bag failures, spills, or difficult closures saves time and hassle. The 21-count box lasts me about three weeks with daily use. I appreciate that Glad has perfected what seems like a simple product. These bags just work reliably every single time. Highly recommend for anyone tired of dealing with inferior trash bags!

Scent: Unscented, Size: 70 Count (Pack of 1)
Will continue buying these since other trash bags I’ve noticed a lot of leaking. Great for cleaning out cat litter can hold up a good amount of weight.

Fantastic towels at a great price on subscribe and save
Package Size Name: Family, Size: 286 Count (Pack of 6)
As an oil painter, Viva are the gold standard for wiping brushes and whatever else you need a towel for while painting. I bought them for that purpose. I didn’t count on loving these paper towels for every other paper towel duty in my home. These paper towels are incredibly hardy, and perform much like a thin cloth towel. They last and last. I can rinse and reuse a towel to clean all the kitchen counters plus clean the stainless steel gas cooktop. All with one section of paper towels. I couldn’t do anything close with any other brand I’ve used. I love the select a size feature. For quick cleanups, one section is more than adequate. I’ve used one section in my swifter handle when I’m out if swifter cloths (which is always- I never buy those things), and used both sides of the towel to dust mop my wood floors. I use these to dust my home with a little spray wax, cleaned the tires on my car with no towel shredding, and scrubbed the filthy barbecue with bleach cleanser, rinsed it out, and scrubbed some more. These towels are tough yet soft, sturdy and disposable. They are soft enough to use as a napkin, and absorb like crazy. I buy mine by the case from Amazon subscribe and save every three or four months, and love saving 20% doing so.

Viva is the best and, by usage, the most economical paper towel
Package Size Name: Family, Size: 286 Count (Pack of 6)
Still basically the same Viva. I compared this version with the prior one I still had on hand. This one has a slightly woven vs felted appearance and the side against the roll is slightly rougher or textured, while the outside face is slightly smoother. The inside face looks as if it might leave lint, maybe. Half sheet size is the same and both versions absorbed one ounce of water. Both seemed equally thick, judging by the amount of see-through-ness, both dry and wet. Both seemed equally tough wet. This version clings to the roll less firmly, too. Viva is the very best AND the least expensive paper towel available based on how long it lasts. It takes weeks to go through a roll, especially if you realize a sheet can be reused to wipe up more than one small mess while you cook and you need many fewer to clean up the big messes. Use one to dry a pot and leave it by the cutting board to wipe up. If you're used to ordinary paper towels, there may be a period of adjustment, but try to take just one sheet instead of the 4 you may think you need; you can always get another. They can scrub an iron skillet or pat dry your food. They make the best handkerchief substitutes, too. One subscribe and save box lasts me about a year.
