125 gr. 30 cal. question

[.270]

well, guess i just wasted a grand on a barrel. too bad, he seems like such a nice guy. i guess he bought all them trophies and stuff. wish i wouldn't o' paid him with hunnerds. he probly needs the money worse than me anyway. there's lotsa ways to shoot and lotsa ways to get it done. i think my new barrel will work real well. it worked great with the ol' factory barrel, before i shot it out. i can't wait to smell gunpowder on a cold morning and watch a bull go down.

I wouldnt say you wasted any money. 11x is a good all around and probably the most versitle twist in 30 cal. It may not be the most optimum for 165's but it will work fine. I have even used the 11x for 150's and 155's. Again, not the most optimum but still yields good results.

 

Let us know how the rifle turns out.

If you want to know what is best, read the match reports for the F-class and 1000 yd BR stuff and see what twists etc are WINNING.

 

If you look at FACTORY varmint and tactical rifles in .308, they almost all have 1-12" twist which is considered excellent, if not ideal, for the 168 grain SMK that all the good factory ammo uses.

 

That said, it really limits you on useing anyting longer. My 300 WBYs all have 1-12" twists because they were built before I had range finders and I shot 150 and 165 grain bullets. My next one will be a 1-11" twist,

 

You said that your twist is sort of a weird one- not really, I know some match shooters that swear by 1-11.25", now that is weird!

 

 

 

You done good Lark!

I am one such nut. The only reason I am currently using an 11 versus an 11.25 is due to timing. I needed a barrel NOW and I couldnt get an 11.25 now. I was able to get an 11 now so that is what I replaced my old barrel with. I have used 11.25 on 2 hunting rifles and a match rifle. For the 30 cal, I believe it to be one of if not the most versitle twist available. The best groups and scores I have ever shot were with the 11.25x. Maybe it is because I have fired more rounds with the 11.25 than any other who knows.

 

FWIW, many a BR guy has shot the 168's with a 14x barrel. The 12x will handle much more than just the 168's.

I am sure glad I spent the better part of the last year + researching this type of stuff for my measly little builds or I and most of the members of this site would have no clue as to what the heck you guys are talking about

I would say 90%+ of the members that have looked at this post once maybe twice and will not look again since it does not pertain to anything they care about and that is fine.

Glad there is a separate category for it.

I for one enjoy it but am just smart enough to get myself in trouble

308Nut you have contributed a lot of info since you joined and with anything I read

I read it all with a grain of salt

Thanks to all who have posted and I hope we have more topics like this.

If anyone is interest in this type of stuff a really good place to check out (as has been stated)

Oh By the way Nut, if you got off the 308 and did what you did with the .284

you would be THOUSANDS of dollars richer

Kind of like Lark with the .270

[308Nut]

Sorry. I prefer bigger bullets than what the .284 offers. If I were a more dedicated match shooter, I would use a 6.5 or 6mm. From a long range hunting standpoint, I will take the 308 over the .284 every time. There just are not enough benefits to using the 7mm-08 over the 308 to make me switch. In fact respecting exterior ballistics, neither makes either inferior contrary to poular belief, espescially at hunting ranges suitable for these calibers. That said, I will opt to utilize a slightly bigger hole and more mass upon impact. Since I am a 1/2 hearted match shooter, I use the same caliber for matches as for hunting. I can nail down a 200/200 at 600 yards without much trouble with the 308 even with modest wind. With results like that and a bigger hole in the critter, I see no need to go any smaller. Now for a bigger cartridge such a a 7mm RSAUM or WSM, I am very interested in those for a 1000 yard sheep rifle. I can see the benefits to using a .284 bullet in these bigger cases. By using a 168 or 180 berger coupled with the good velocities these cases offer, it is actually usefull. To use the 168 or 180 in the 708 case doest afford much range due to expansion/minimum velocity impact requirements. With the bigger cases, it is much less a concern.

 

Not sure why I would be richer using a 284. I think I would go through barrels a bit faster using the smaller bore. In this sense, I am richer for using a 308!?

 

I am glad you take my thoughts with a grain of salt. I know I can be very rough around the collar! At least I come by it honestly.
