I'd take 2900 but I think the .308 Nosler 125 grain would take a faster twist rate. Any ideas????

Need more info. Out of a 26” barrel on a TRG-22 I’ve gotten 155 Scenars to right at 2900 but the loads were spicy with cratered and flattened primers. Not ideal. With a 140 gr .30 cal bullet. (if such an animal exists) or with a 30/32” Palma rifle you should be able to do it with 155’s.

Barnes tsx's start at 110 grains and go up....they should easily get you where you need and still be affective...

I get over 2950 fps from my single shot 40X with 155 grain Sierra #2156 bullets and IMR ; well hell, my memory escapes me right now, I'll check the charge later.
I have never checked the rifling twist in that rifle or don't recall if I did. ETA:. My load is 46.8 grains IMR 4895 in Winchester cases with GM210M primers seated to 2.80 inches COAL. |

First, why?
Second factory ammo? Hornady Superformance 150 SST lists 3000fps from a 24" barrel. |

I'm presently shooting Hornady Match 168g ELD. I need to drive a smaller bullet toward 3000 fps. Maybe even 3190 but not beyond. This is for match shooting only. Money isn't really an issue. I'm an old guy trying to relive his youth. I do NOT want to hand load as I've been down that road a few thousand miles. I just want to have fun and be "somewhat" competitive. Well winning isn't so bad either.

Velocity doesn't win matches. Those 168s are a good match bullet. They have a good BC and plenty of velocity in factory ammo. I shoot them in Tac class in PRS style matches.
What matches are you shooting? |

I'm more confused and still wondering what you are asking about twist.

Switch to 175 grain MatchKings for 1000 yard class distances.
That bullet was developed to get M1A rifles to 1000 yards. The new tipped 168 gr MK has about the same BC. I haven't tried them. |

OP, since you insist on factory ammo, I'd try these:
175 Berger Factory Ammo ETA: Or these: 175 Lapua |

Thanks for the responses guys. I really really don't want to go down the rabbit hole of reloading. I got my son started in PRS and have no interest in weight sorting cases, turning necks, using tweezers and on and on. I just want to be able to get something off the shelf with an SD of less than 20 and go have some fun. At my age ( 66) just finishing a match with no issues is a good time for me. I have no pretense of being in the hunt but I have great equipment and SOME ability. The people in the PRS are super and I know many of them. The nature of the beast requires some shots out to 1200 or even beyond. Therein lies my issue as the .308 is not in the same class as the "hot rods".

This is what you want for 308 and 1000yd plus.

I just got off the phone with Hornady ( very helpful) and I think I'll go to the Super Performance and just shoot open. I'm never going to win anything anyway. My whole point was just to be able to shoot as well at 1100 as I do at 800. My 6CM is on its way but I don't know when it will get here though soooooo we'll keep on shooting my .308 'till it arrives. I will crono this ammo and SEE what it really is and if it is below 2800 I'll stay in the tac division. This whole deal guys is just about me having fun and hanging out with the best folks on the planet anyway.

Don't get hung up on the velocity and reaching 1100 yards. The ELDs and BTHP do fine in the transonic and even though they go through it they still shoot well. I have shot 168 ELDs at 2750fps out to 1200 in matches. Shot the old 178 AMAX to 1350 yards and it was only going 2720fps.

Well the rules are the rules so just go by those written rules and not what anyone says even if it is Shannon.
Also the velocity on the boxes are not far off. Actually with the 178 superformance load in my 20" rifle I get 2805fps so I would bet the 168s are going faster. |

Well I now have even more issues. The Hornady Super performance has an SD of 15.3, ES of 37 and an average velocity of 2912 fps. Besides that the grouping PALES in comparison to the regular Hornady Match ammo. Both are shooting the 168 g ELD bullet. I'm taking a step backward IMHO if I switch. I observed ZERO pressure signs at all. I may shoot another couple of mags through it . We'll see. Shannon told me a 10% variance but the book says 1% so I'm sure that was a typo.

The Superformance loads are finicky and some shoot them well and some don't. So if the standard load is better then use it.
As for the rules, get it in writing before you go to a match but honestly I don't remember ever seeing them chrono anyone. Like any law/rule it just keeps the honest people honest. |
