  • 243 Winchester Super Short Mag (WSSM) in 75 Grain V-Max- Hard to find, but we have you covered!! The 243 Winchester Super Short Magnum or 243 WSSM is a rifle cartridge introduced in 2003. It uses a .300 WSM (Winchester Short Magnum) case shortened and necked down to accept a 6mm diameter bullet, and is a high velocity round based on ballistics design philosophies that are intended to produce a high level of efficiency. The correct name for the cartridge, as listed by the Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI), is 243 WSSM, without a decimal point. Winchester has discontinued the manufacture of 243 WSSM ammunition.

    This cartridge is usually used for small game such as varminting, and used for animals as large as deer. Choice Ammunition offers this caliber in several choices of bullet selection, all 100% Hand-Loaded for superior performance, reliability and accuracy!

    The Bullet

    Hornady’s V-Max Bullets feature a polymer tip which enhances accuracy and promotes devastating expansion. The tip raises the ballistic coefficient for faster velocity and helps to stabilize the bullet in flight. It also acts as a wedge, initiating bullet expansion. The copper jacket provides the necessary bearing surface for maximum stability out of the barrel, and the jacket is built to withstand the fast twist rates of the most advanced varmint rifles.

    The Bullet

    The Hornady line of traditional Varmint bullets features a streamlined design for flat trajectory. Its lead core and match-grade copper jacket represent the original standard created by Joyce Hornady for classic varmint hunting. Primarily comprised of spire point profiles and flat base designs, the bullets perform extremely well even at low velocities and deliver excellent performance in many classic varmint rifles.

Thank you for visiting Choice Ammunition!Home of Premium Ammunition- 100% Hand-Loaded in Western Montana.

As you may know, the ammunition and firearms industry is experiencing unprecedented times beginning with COVID 19 coming from China in early 2020. Some talked of defunding police departments about the same time, even as riots and lawlessness raged on in our cities with unrest. We then saw a very contentious presidential campaign and ultimately- an inauguration of what could be a very unfriendly 2nd Amendment administration controlling both houses of Congress. For these reasons and more, we see demand at all time highs in the industry, in addition to mass shortages of components. I personally do not see things changing any time soon either...

With this, we are doing everything possible to hand-load and get products shipped in a timely manner, but we cannot simply turn machines up like others! Any back-orders on this website that we allow, we feel will ship in a reasonable period of time and we are averaging about 2-3 weeks presently. However, we are reliant on our suppliers to deliver components to us also, and that can unexpectedly be delayed on occasion. When this happens, it is possible to see 30-60 days, and sometimes more- to get ammunition sent out to you. Please know, all backorders will be filled at the price you purchased the ammunition for. If you find something elsewhere- we are happy to cancel any order.

We try to answer all office calls and prefer calls over emails or social media. We ask you to please refrain from calling or changing your order unless it is absolutely necessary- keeping in mind the time-frames I mentioned above. Every call we answer removes the focus on sourcing components and loading/shipping your ammunition!  We promise to get your order out as soon as we possibly can- yet, ask that you please understand this crazy market we are all in- if indeed you are delayed!

We do not believe in price gouging or increasing margins in a market such as this- and we will do everything possible to remain competitive with “factory” ammo, while providing our premium hand-loaded ammunition to the market. It does appear that prices may increase this year however, as there is much volatility in pricing for our brass, bullets, powder and primers.

Thank you for considering Choice Ammunition if you are a new customer- and thank you for another order if you are returning. We truly appreciate all of you and have built our business from going the extra mile with our products and for our customers!
