    Reply to  Rumper

    The choice of the best grain (bullet weight) for shooting out of a .243 WSSM depends on the specific purpose of your shooting, such as hunting, target shooting, or varmint control. Different bullet weights offer varying performance characteristics. Here are some common options and their typical uses:
    💠 55-70 grains: Lighter bullets in this range are often used for varmint hunting and pest control. They offer high velocity, flat trajectory, and explosive fragmentation upon impact, making them effective for smaller animals like groundhogs, coyotes, and pests.

    💠 80-90 grains: Bullets in this weight range strike a balance between varmint hunting and medium-sized game hunting. They offer good versatility and are suitable for deer-sized game at appropriate distances. They can be effective for both hunting and target shooting.

    💠 95-105 grains: These bullets are often favored for medium to larger game hunting. They provide better penetration and energy retention, making them suitable for deer, antelope, and similar-sized animals. They can also be used for long-range target shooting.

    💠 110-115 grains: Heavier bullets in this range are generally well-suited for larger game hunting. They offer excellent penetration and energy transfer, making them appropriate for animals like elk or wild boar. However, recoil might be more noticeable with these heavier bullets.

            Why does the 243WSSM, which appears to contain nearly the same volume of powder as a conventional 243win, burn barrels at an exceedingly high rate, unlike its standard counterpart? This claim is often made, but no explanation is ever given.
            Frequently, there are mentions of feeding problems … but are they prevalent in most rifles? If anyone has any information, could you provide some insight into what might be causing these issues?
            I neither support nor oppose the WSSMs, my goal is merely to unearth the truth… as most of the information I come across seems biased.

              The 243WSSM and 243 Win both use a .243 caliber bullet, but the WSSM case is shorter and has a smaller capacity than the Win case. This means that the WSSM cartridge must be loaded with a higher powder charge to achieve the same velocity as the Win cartridge. The higher powder charge results in a higher chamber pressure, which can increase barrel erosion.

              ☑️ In addition, the WSSM case is tapered, which can also contribute to barrel erosion. The taper of the case creates a smaller chamber volume at the base of the case, which can concentrate the chamber pressure and lead to more erosion.

              ☑️ So, the 243WSSM burns barrels at an exceedingly high rate because it is loaded with a higher powder charge and has a tapered case. These factors can increase chamber pressure and concentrate the heat, which can lead to more erosion.

                The Microlon barrel treatment, developed by an inventor dealing with rapidly deteriorating barrels due to extreme calibre and loads, has proven to be remarkably effective. He pushed the bullets to their limits, to the point where they were nearly disintegrating upon exit. However, using Microlon treatment, the barrel shows no signs of damage even after 5000 rounds, a stark contrast to the mere 200 rounds it could withstand without treatment. This solution is ideal for handling aggressive cartridges.

                  The “barrel burner” reputation of the .243 WSSM arises more from velocity than powder volume. With a slightly higher powder load than the .243 Win, it achieves around 200 fps more speed. Regular use at those high speeds can wear out barrels quickly, much like the 22-250. The WSSM and WSM cartridges, while high-performing, haven’t continued to sell well due to their marginal advantages over classics like the .243 Win or .270 Win. Their benefits, like slightly higher speeds or shorter actions, don’t constitute dramatic improvements. The appeal of the WSM models, for those like me who own them, is their uniqueness. For handloaders, the cost difference is negligible. While owning a .243 WSSM would be interesting, my .243 Win serves all my needs for a .24″ bullet.

                        I have a Model 70 in 243 wssm, a cartridge that offers impressive performance. It’s been instrumental in hunting several whitetails and antelopes. Regrettably, it didn’t gain much popularity. Before the ammunition scarcity, Hornady pledged to produce brass for it, but I believe they only manufacture it sporadically. I carry out my reloading, so when I realised the WSSM’s weren’t becoming mainstream, I secured 300 empty cases.
