  1. Rifle reloading data | Handloading | Rifle calibers | Centerfire Rifle bullets | Reload your own ammo - Vihtavuori

    I have a Ruger Precision Rifle (6.5CM), which my son shoots. I am using N160 (41.5grs), with 139gr Lapua bullets, Hornady brass and Federal 210 primers. This equates to: (2616/2612/2616ft/s) = 2614.4 ft/s average. This has proven the most accurate load. However, we have tried the following loads with 139gr Lapua bullets, Hornady brass and Federal 210 primers:

    40.1grs: (2543, 2531, 2538) = 2537 ft/s

    40.2grs: (2554m 2515, 2528) = 2532 ft/s

    40.3grs: (2544, 2556, 2559) = 2548 ft/s

    40.4grs: (2534, 2536, 2559) = 2543 ft/s

    40.5grs: (2562, 2548, 2553) = 2554 ft/s

     41.0grs: (2536, 2596, 2592) = 2574 ft/s

    42.0grs: (2587, 2634, 2636) = 2619 ft/s

    42.5grs: (2679, 2670, 2658) = 2669 ft/s

    43.0grs: (2700, 2683, 2695) = 2692.6 ft/s

    43.5grs: (2723, 2712, 2712) =  2715.6 ft/s

    These all worked fine in my rifle, I don’t know about anyone else’s.

     

    We decided to chose accuracy (group) over velocity. We mainly shoot at Diggle range and using N160 (41.5grs), with 139gr Lapua bullets, Hornady brass and Federal 210 primers, my son has managed to hit the egg, fly and achieved numerous small group patches in the factory 600 yard benchrest competition.  However, when shooting beyond 600 yards i.e. up to 1000 yards, we do lose out to those achieving higher velocities.

     

     

  2. I have a standard Remington 700 (.223) which is a 20" barrel, 1:9, in an MDT chassis with aftermarket trigger and I shoot out to 600 yards (factory benchrest) using 69gr Sierra Match King, 25grs of Vihtavuori N140, the velocity is 2811ft/s (this works in my rifle, don't know about others). If I didn't need the rifle to be factory class, when a new barrel was required, I would be looking at 24"  - 26". For a factory rifle, with a 20" barrel in my opinion it shoots very well.

    The images are 600 yards benchrest competition (5 shots) and when I was developing my load for a 100 yard zero (3 shots).

    Had mine about 10 years ago and the only place doing the work was Low Mill Ranges in Cumbria.

    http://www.lowmillranges.co.uk

    No idea if they still do that sort of work, but might be worth asking them.

    I sold my Steyr Aug last year, prior to that as BamBam advised above contact Low Mill Ranges, they did my modifications (barrel release button, trigger tamer, modified charging handle) - see image.

    There's a Sightron SIII 8-32 on sale here for £550, including mounts.

    ^^this, I had one of these on my RPR (6.5CM) for a while and my son regularly shot out to 1000yards. In my opinion, for the money unbeatable.

  5. In my Ruger PR (24" barrel) - these worked in my rifle, don't know about anyone else's rifle.

    Hornady brass, large Federal primers, Hornady 140 AMax bullets, Superformance (43.7): 2591/2608/2583ft/s. Although, I don't believe that you can buy this powder now.

    Hornady brass, large Federal 210 primers , Viht N160, Lapua 139 bullets

    40.5 - 2554ft/s

    41.0 - 2574ft/s

    41.5 - 2614ft/s

    42.0 - 2587 / 2634 / 2636ft/s

    42.5 - 2700 / 2683 / 2695 ft/s

    43.0 - 2700 / 2683 / 2695 ft/s

    43.5 - 2723 / 2712 / 2729 ft/s

    Currently using  41.5 and my son is shooting 600 yards not a problem (used in factory sporter benchrest). However, whilst operating the electronic targets at 1000 yards, would benefit from a greater velocity. The intention therefore is to increase the load from the current 41.5 (chose accuracy over velocity).The higher loads noted above didn't give the best accuracy, so going to have another go (when the ranges are open).

    I have an Armalon PC carbine in 9mm, which is built on a Lee Enfield No4 action. It is truly a work of art. 

    I would be interested to see a picture. I have always liked the look of Armalon, however, they do seem quite expensive (but I assume to pay for what you get).

  7. I am currently load developing my factory Savage 6BR at the moment (with the assistance of The Gum Pimp on here) for my son to use in factory benchrest and the results so far are as follows:

    Case: Lapua

    Primer: Federal 205 (although, these may need to be changed, a few primers were holed)

    Bullet: Berger 105 VDL

    Powder: Viht N150

    29.0grs: at barrel: 2753ft/s (this looked like over pressure (stiff bolt), but was actually too little powder)

    29.3grs: at barrel: 2776, 2777, 2777 = 2776.5ft/s

    29.6grs: at barrel: 2791, 2795 = 2793ft/s

    31.2grs: at barrel: 2902ft/s

    31.4grs: at barrel: 2932, 2938, 2931 and at 600 yard target with Shot Marker, 1955, 1946, 1951, 1961, 1948ft/s  

    31.5grs: at barrel: 2921ft/s

    31.7grs: at 600 yard target with Shot Marker, 1963, 1964, 1948, 1971, 1966ft/s

    31.8grs: at barrel: 2943ft/s 

    32.0grs at 600yard target with Shot Marker, 2005ft/s) pressure signs

    32.1grs: at barrel: 2971ft/s pressure signs

    Next test will be using: 31.2grs and 31.5grs (these didn't show pressure signs, produced the best group so now looking to optimise the group and will develop further around these loads).

    These tested in my rifles, don't know about yours!

  8. I would agree with a Sightron 8-32x56, whilst new around £1000, secondhand should be around £500/£600. Also, more than capable of shooting out to 1000yards.

    I am not convinced about a .223 for 600yards with factory ammunition (agree that ammunition would be plentiful and the least expensive option). I would still go .308 for the choice of factory ammunition (more expensive than .223), but 6.5 Creedmoor would be better, however, less choice and more expensive factory ammunition (could buy Hornady and save the cases to reload at a later time).

    Mark,

    The 'factory ammo' bit is probably your main factor? As per above, probably 6.5 Creed(s)moor. Shot a friends Tikka Tac using Hornady factory ammo a little while back and was really surprised at its consistency.

    If you reloaded, even using basic tools, then a 6BR would be my choice out to 600 (and probably a bit further). Think Savage do a target type rifle in 6BR.

    T

    Savage do indeed manufacture a target 6BR, I have just bought one secondhanded one, it's their Benchrest rifle (less than 200 rounds). It is exceptionally accurate and my son and I are still developing the load using Viht 150 and Berger105gr VLDs.
