Any comments on 7mm-08 as a precision rifle?
I've used one in UK F-Class and the occasional mid/long-range BR match for several years. It was intended and chambered for 160-168gn class match bullets, specifically the 168gn Berger VLD seated to around 2.99" COAL. My original intention was the AI chamber, but when the rifle was being rebarrelled from its previous 308 Win F/TR form, the previous great US buying surge was underway, (Barak Obama's reelection for a second term?), and it was going to take forever to get a reamer from the US. So, plain-Jane 7-08 Rem it became, albeit with a minimum-SAAMI 'match' chamber. I still regret that as the small extra AI capacity would have been very valuable. I know one or two people using the AI in tactical / PRS type rifles and they're very pleased with the performance running at AI magazine COALs with 26-inch barrels shooting ELD-Ms mostly.
The 168 VLD bullet became problematical for the usual VLD reasons and Sierra had just introduced the 160gn TMK, a nice easy bullet to tune, very consistently made, and it shoots well. So, it's largely used them since. A compressed load of Viht N160 in a necked-down 308 Win Lapua Palma small primer brass gives the 160 2,865 fps (31-inch Bartlein). I've recently been experimenting with standard large primer brass and reckon that they give better results, albeit at only 2,805 fps, still with N160 and the 160gn TMK. I've shot 'possibles' at 300 and 500 yards several times with this set-up usually off a super-wide bipod (grass firing points) not a front-rest and had a fair few F-Open firsts and many seconds and thirds in a very competitive club F scene. Sadly, these have become rarer in recent times, partly me, but more the F-Class 'arms race' where 284 Win has become the minimum firepower ... and when you compete against 300 WSMs at 300 yards these days ..........!? So, it just does 300 yard matches these days. I also have some 162 ELD-Ms loaded up at various COALs to see if I can make them work for their considerably higher BC.
I could also uprate the ballistics with hotter powders - Re16 and 17 to name two will take the 160 to 2,900 fps or more, albeit the limited 7-08 case capacity sets limitations on how much bulky Re16 you can stuff in. I settled on N160 early on, also the cartridge itself to get good barrel life, so I could shoot it a lot and not worry about remaining barrel life during and after each session. It's up at around 2,300 rounds and still going very strongly.
I have tried it with 175s and 180s and it'll shoot them fine too, but the freebore needs a considerable hike to suit them, and I'm not talking recent super long-nose introductions even. Recoil increases noticeably too, and part of the pleasure in shooting it with 160s in a 20lb rifle is its moderate recoil and excellent manners on a bipod off grass saving me lugging heavy front-rests around to the more difficult to access firing points. Not as easy to shoot as my 20lb + 223 Rem F rifle mind you, but that's like shooting a noisy long-range rimfire! I have a 284 too and that's what I shoot 175/180s from - a much better suited cartridge for this purpose. (Use cool burning Viht N165 and keep pressures down and it'll give good barrel life too, albeit still less than 7-08 I'm sure.)
I also have a second staple bullet / load, the 150gn Lapua Scenar-L in prepped Winchester brass pushed to not much over 2,800 fps with Lovex SO65 (Shooters World 'Long Rifle' in the US). This gives excellent short-range precision, quarter MOA, sometimes considerably better, with five shots at 100 and shoots well to 300/500. I won several 300 yard club matches early on and had the odd very good result at 500 with this combination before the opposition upgraded to short magnum 'Dreadnought class' battlecruisers.
I should mention I shoot on a notoriously wet and windy range, so ballistics are often needed in addition to precision. I have taken the 284 to 500 yard matches, sometimes even 300 if the weather forecast was too threatening.
