Re: 308 Load Help

as far as a scope....

20X is as powerfull as you want ot get. after that mirage will kill you...

I was using my Nightforce 3.5-15X50mm I had it on 15X and the mirage was bearable in it.. I was killin small rocks to 1150...

for a 308 15X is as much as you need..

Not sure of your $$ situation.. but the 3.5-10 lupy tactical M1 would be a good place to start... the new 4.5-14 LRM1 is very nice but not available until April.

I know guys that like the atarget scopes.. but I like mine without caps...

just my .02

DB i think you're joking right???

I'd venture to say it can't be done with consistency... but some guys claim some pretty unbeleivable things...

DB

I think the case your talking about is not the 308 Winchester case.

The 308 or 300 A was an improved 300 Weatherby case with a sharp shoulder that would hold upwards of 100 grs of powder.

The 308 Win case just don't have the boiler room area for enough powder to get to 3000 yards and seat a 220 gr MK in it too. [img]images/icons/wink.gif[/img]

Re: 308 Load Help

LA, I would agree about using Varget in your 308, I've used 47gr. 4064 with 150gr.BT which is pretty close to Varget and got 3/4"groups(3shots) @100yds with my Browning stalker(don't laugh you LR guys, please) And yes Benchmark is supposed to work exceptionally well for the 155Palma bullet, I will try some someday since I bought some for my 223Rem. I don't want to start up a big discussion on scopes again, but I don't think you need to spend 1300+ on a NF, As I said in a previous post my lowly Burris Signatures in 4-16 and 6-24 will compare to any scope out there, they got your Fully-multi-coated lenses that will rival any scope and are repeatable with the best of the best, God at least I hope anyway, he,he. But seriously, they are a great scope without paying exorbitant prices. Jay [img]images/icons/wink.gif[/img] 1-888-228-7747 for a free catalog

Re: 308 Load Help

Thanks again for the info guys!! This is a great board. I was leaning towards a leupold, but still debating on which model and reticle. Any suggestions here? If not I will start another thread on this new topic.

Re: 308 Load Help

LA, That thread was already started, 6 pages and 78 posts ago, at any rate with my Burris 4-16 Sig. w/Balmil-dot or a Black Diamond w/same reticle you can zero your rifle @400yds or maybe a bit higher since your using a 308 and where the bottom(thick part) of the reticle joins up with the thin part could be your 1k zero, you can call Burris to get any advice on setting it up for a 308 if you go with the Burris, my scopes are holding zero very well as they should, getting .217-.322" 5 shot groups w/6mmRem stock barreled action, and I'm sure they're maybe alot of scopes out there that when you point the scope towards the sun you'll get zero glare, same for Burris. Friend has 243Win. 700 Rem. w/8.5-25-50mm, getting similar groups and he paid $400 more, I think he got mad when I showed him my .217" group cuz he knew he paid too much for his Leu., told me he would be mad if I shot as good as him months before, but yes he has more elev. I'm getting more light coming through than he is(brightness). Both outstanding scopes, got a Leupold 3.5-10 pre- Multicoat 4 myself. I'm just value minded I guess.

Re: 308 Load Help

LA,

Not sure if someone mentioned it, but what seems to work well in more than a few rifles is Varget, w/ SMKs. Some rifles won't go as high w/o showing pressure, but what shows good accuracy in my Rem700Vs is this: Winchester cases, CCI BR2 primers, and then either 46.0gr Varget for the 168SMK, or 45.0gr for the 175gr SMK. Others have had good results w/ up to 47.0gr Varget and the 155gr Palma SMK, but my gun doesn't do well w/ 155's [img]images/icons/frown.gif[/img]

4064 is a great powder for the .308, and has been for years. Accuracy is often phenomenal, though velocity is a little less than some newer powders, and it would be a courtesy to say it meters like hell. Definitely a weigh-every-single-charge-and-trickle-up affair, which may be a non-issue for you, as many/most LR shooters do that anyway.

Alliant RL-15 has been around a little while, and it is another of the short-cut extruded grain powders like Varget and Viht N140. I think the official U.S. sniper round for the .308 Win now uses the 175gr SMK and RL-15. Not quite as accurate as Varget in my particular gun, and has a funky smell to it also [img]images/icons/wink.gif[/img]

Vihtavouri N140 works well in the .308, and I've talked to some HBR shooters who got phenomenal groups using it. Lately I've not heard much about it beyond some rumors that it was turning out a bit more temperature stable than Varget.

Varget is part of Hodgdon's 'new' (last couple years "new" ' Extreme powder line manufactured down in Australia. Very temperature stable, about the only downside I've heard to it is that every new lot seems a little cooler than the last. Haven't really noticed it myself, but then again, my chronograph is on the fritz, and I don't have detailed LR data of my own to compare against. Each can I get still puts them in little holes w/ the 175gr SMK.

If weighing every charge (4064) doesn't appeal to you, try something like Varget, RL-15, or N140, as they throw to acceptable tolerances in most powder meters (i.e. +/- 0.2). 'Acceptable' depends entirely on the load, and how sensitive it is to slight variations. I really didn't see much in the way of SD/ES (sorry, can't remember the numbers) difference btwn thrown +/- 0.2gr, and weighed down to the gnat's ass every charge. Lastly, if throwing charges vs. weighing is what you want, but you don't like the +/- of Varget and the other short-cut extruded powders, try Ramshot Tac. Their powders are all supposed to be pretty temp stable, and are a ball type powder, so they meter about like water [img]images/icons/wink.gif[/img] Velocity was down around 4064 in my gun, which wasn't bad, it's just that Varget was sooooo much better [img]images/icons/wink.gif[/img]

As for the scope, well, different strokes for different folks, i.e. depends on who you ask. S1 *really* likes the NightForce scopes, and has used them in professional (read as: taxpayer dollars) applications. Other knowledgeable folk, like Darryl Cassel, have a preference for Leupolds. At least one serious shooter here uses Nikons, Bausch & Lomb, etc. As you probably figured out, Jay is the resident messiah for Burris. Me, I've had Leupold LR/Ts, had some issues w/ them (not quality, just compatibility btwn them and me) and plan on getting a NightForce most likely. Meantime, the stopgap measure for me is a Sightron 6-24x. Not a first choice, and it does have some limitations, but so does my budget at the moment [img]images/icons/frown.gif[/img]

Check out the models that interest you. 30mm main tube is a plus, as is side-focus and target turrets, though none are absolutely essential. Lots of elevation adjustment is nice, and drives the price up rapidly on the higher-magnification units. I'd say about the only absolutely-must-have feature that you should not go with out is parallax adjust, whether in the form of an adjustable objective (AO), or a side-focus. Fancy reticles are neat whiz-bang items, and take some time to master completely to the point where they save time and ammo rather than waste it, but they do have a time and place.

As always, your mileage may vary (YMMV)
