Re: building another lr rig

I was also thinking of mentioning the 30x284 if you are into wildcats, it has been used on occasion for 1000 yard br, dies are available from redding, the best way to go about it is to get 6.5x284norma brass, either the norma or lapua brand run them through a 284win fl die, then through the 30x284 fl die. It fills the middle ground between 30-06 and 300win mag, just shy of the 300wsm, but has longer barrel life than the win mag or wsm and is slightly more accurate than the tried and true 06, in a 26" 11 twist barrel with the proper throat it will break the 3000fps mark with 185grn berger vlds and H4350 and is easy on cases. A cheaper way is to get winchester brand 284 cases and do a single pass in the 30x284 fl die but the cases do not last as long. It is a very accurate, easy to load, fun to shoot caliber with moderate recoil or virtually none with a muzzle brake. The regular 284win with a long throat shooting 168 vlds is also a very efficient round. The 284 is simply an awesome case for all non magnum wildcats.

Re: building another lr rig

I second the 308.
I have a 338 Ultra mag, a 7mm/300Wby, and a 25-06. I picked up a Rem. 700 SPS Tactical in 308 that has a 20 inch tube at the beginning of the year and have had a blast shooting it and working up loads out to 500 meters. It is my short range ( to 500 yds ) go to carry rifle.

Re: building another lr rig

Ok, so I made the commitment and pulled the old barrel off of my rifle. I decided on just doing a 308. I will be going with a pacnor med palma now I just need to know what twist rateand barrel length? I am wanting to run the 168 gr berger vld or something around that weight.

My 308W has a 22" barrel 5-R Krieger 11 twist. And shoots everything from 110 gr V-Max @ 3300 to 210 gr bergers at AV 2335. I normally shoot a 175 bergers with 46.5 gr H-4895 for 2770.

Re: building another lr rig

Mine is a 28" 1:12 twist. I find this to be the optimal twist for a 155-190 grain bullets. I am getting great results with the 168 Nosler Ballistic Tip. I am going to order some 168 Berger Hybrids and give them a run to 1000yds. With a BC of .519 and being the Hybrid design, I have high hopes for this bullet at that distance. I would say 24-26" would be a good carry length weight barrel. Mine is a Savage varmint contour. No flutes. Thinking about your application a 24" would be the best fit. It gives you enough length to get you as far as you want to shoot, w/o suffering any major muzzle velocity loss. Using RL15, AR Comp, or Varget will get you to around 2600-2675 with a 175grn bullet. You will be looking at 2700-2750 with a 168. That would be sufficient to do what you want.

Re: building another lr rig

For a 308, I would never go with anything slower than a 12x. With a 12x you can stabilize 200's (except for all copper) but it is not an optimum combo. For 165-190's, the 12x will serve you well. For 190-210, the 11x will do well. Anything over that go 10x.

All that said, the 11x works well with 150-190 grain bullets. It is my favorate twist for the 308 but my next one will be 10 for some of the mono metal bullets.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
