7mm STW
@ 01:54 pm (GMT) |
Robert BissonI apologize if this information is already posted, but I was short on time to search the forum. I'm building a "semi" custom Rem 700 in 7mm STW. Basically stripping down a SPS, new HS Precision stock, trigger job, bedding, and full Cerakote on the metal. I do hunt South Texas from time to time and found the 7mm STW very popular. Although, I usually hunt the Texas Hill Country and have shot 90% of my deer with a 22-250 which has worked very well. Every deer has dropped like a sack of rocks. I also use a 25-06 with the same results as my 22-250, including a Sitka Blacktail on Kodiak Island. I've never been a fan of the magnums due to recoil, but felt I should get a gun with a little more power for hunting Alaska. I went with the STW because it seemed to have really good ballistics without the recoil of a 300 Win Mag. But since I plan to use the gun on deer in Texas, I wanted some opinions on the 140 grain bullets and what some of you guys are using? I purchased a couple of boxes of Nosler Custom 140 grain ballistic tips since loading materials (brass) has been hard to get. |

sllindsayRe: 7mm STWI don't know anything about the 7 STW myself, but probably just about anything you would want to know is over in the Knowledgebase/Cartridge Research/284 7mm section. |

Nathan FosterRe: 7mm STWHi Robert, yes, please check the Knowledge base for cartridge info. I have also gone into further detail in my second book.If you wish to use the rifle at long ranges, it may pay to adopt a Wyatt magazine box to better suit the COAL's of the STW. Recoil of the STW is about the same as the .300 Win Mag regardless of computer generated tables regarding recoil. In practice, both a similar when loaded to full potential. If you wish to reduce recoil, a 7mm Rem Mag would be the way to go. The 140gr BT bullet is fairly ho hum at magnum velocities. It will do the business on light bodied Texas deer without fuss but in some ways it under utilizes the STW. You will certainly experience some spectacular kills with this load but it has its limitations at close ranges on large body weights and at long ranges where the jacket is too stout to initiate expansion. There may also be times at close ranges when game show no sign of a hit because the bullet has fragmented on impact but met too much resistance to impart hydrostatic shock as a result of impact velocities, not game body weights. But as a general 100-400 yard bullet on light framed deer, you will be happy with this bullet and besides, it is the brass you are after. Please have a good read through the knowledge base Robert, from the 7mm Rem Mag through to the 7mm Practical through to the STW. Also study the .300 Win Mag data at the same time. You are perhaps too far into the build to make changes now and asking for advice after the build has commenced may be a bit moot. Nevertheless, I hope you find some info of use. Perhaps also have a good think about the cerakote. If the rifle is stainless- do you actually need a paint coating. If so, will the cerakote be employed before or after bedding. If the rifle is cerakoted first, then bedded, the cerakote may chip during the bedding process. If employed afterwards, it may alter bedding tolerances. The book series covers this in detail if you wish to fully investigate such issues. |

Jim MoseleyRe: 7mm STWWhat game are you hunting in Alaska? Didn't know if the twist of your STW will handle the 180-190 weight bullets for the "just in case moment" if you run into something with big teeth and claws. |
