Short Barrelled 6.5

[jthyttin]

While the current trend in service rifles is towards higher mounted red dots (to allow more flexibility between torso and head while moving etc) your two pictures are not comparable since the height (and line) of stock compared to barrel are quite different.

That said, people also assume "fighting position" when under stress, ducking their head lower than normal. So it becomes more awkward and error prone to use higher mounted optics. Or takes a great deal of practice and exposure to stress (=people shooting back at you) to get rid of the effects of "fight or flight" reflex.. Or actually there's third f that is most popular, "freeze".

Problem with poor ergonomics, i.e. high scope install with no support from stock, is that you get less feedback and tend to make mistakes. In controlled situation, your best results might not differ but you make more mistakes. And in stressful conditions, the error rate goes way up.

The pictures were just typical stock pictures used to illustrate, the fashion for low mounts was taken to the max by a former Rigby gunsmith (names escapes me) but we have come a long way since the first large scale use of telescopic sights in WW1.
I find the sported swede carbine to be not uncomfortable to shoot especially standing or from a high seat which is when most of my woodland shots have taken place.
I use to carry it as a guide rifle when taking clients to woods I looked after as it takes down into a small case about the size of a flute or clarinet so I could use public transport if needed!
Anyway 18 inches isn’t too short!

Just built a new rifle for myself
19" 6.5 Grendel on a Sako 75 Action 1
1:7" fluted Lothar Walther Stainless barrel

super light and pointy
loading 95gr VMax and 100gr Peregrine
QL says I should be getting around 2850 from them
more than enough for my needs

not fired in anger yet as only just put it back together

I’m sure we need to have a rule regarding pictures or it didn’t happen! I’d love to see it

You were talking about that a while back .

Glad it came to fruition

I have a 6.5x47L with 18in barrel. Have shot red on the hill and a few roe with it, almost all less than 200yds. 120gn Nosler BT’s, nothing negative I can suggest about it. No muzzle flip with light ATEC aluminium mod. Very accurate and handy rifle to humph about. Not a clue about muzzle velocity, but everything I hit correctly snuffed it quickly and without dramas. Appreciate its not a CM, but similarish.

Here is one of the two 6.5x55's I own both have 20" barrels.

You’re better off going 7-08 with 18”

That’s what I’m collecting parts for at the moment, I’ll be keeping my 6.5cm for the days when I want /need to shoot factory

Ive just tested one of ours at @Cotswold Sporting . Its a 19” phoenix barrel chambered in 6.5cm. Proof rounds only before, i took it there with a Swarovski TDS 6-25x50 from another rifle and shot 140 eldm’s, no load development. 3 shots i was on the 200m fox gong, cleaned it, next 3 all hit the 300m gong, cleaned it. Then went at the 400m gong and hit 2 out of 3. The drops were exactly matching the 22” bartelin barreled PRS rifle that the load was developed for within minute of gong (or deer).

Sitting in factory wood for the moment
Had to fettle the extractor as it ejected the Go/NoGo but not a fired case

Now sorted

Cases fit perfectly in the ex-.222 magazine

Long old mod

6.5x47L, 18” Sassen Barrel. Tikka T3 action, PSE stock. SuB MOA.

Long old mod

Actually the forward protrusion is very little around 12cm

Its a used one that was handed in
Very slim and quite light which is the only reason I am using it

I prefer light end of barrel mods.

At 308 sized cartridges and 50mm OD mods my rule of thumb is that reflex chamber roughly equates one additional inch of mod forward of muzzle (of course there are gazillion factors in this).

With larger cartridges (and I guess slimmer mods in 308 or smaller cartridges), the role of reflex chamber is greatly emphasized unless you want to go silly lengths forward of muzzle.

To be honest most humans can’t tell the difference between two or more moderators firing the same load. Even accurate laboratory testing is fairly pointless to users. The real benefit of moderation or suppression is down range where the supersonic crack is dissipated taking away the ability of the target to hear the direction of fire!
I use B&T mods as they are light and adequate for the job!
If another make had ticked the box I would have used those!

 

[jthyttin]

This might be true on open field or such, but in close proximity of buildings (or other flat surfaces that reflect the sound back), woodland etc. there is a VERY clear difference in mod that is "good enough" and mod that isn't.

There's also substantial difference in the first shot (many times the only shot) and consecutive shots in different mod designs. Most tests pay no attention to this. I've linked a German test here couple of times, that does admirable job of comparing first shot (IIRC 3 separate results) and consecutive shots.

I prefer light end of barrel mods.

Very few with less forward protrusion and they all have significantly larger diameter or the slim ones come with more weight

The chamber isnt as significant as the bore to calibre clearance.
But it is still significant and shown to be in tests

Over barrel Chamber serves two purposes
Gas cooling aids sound attenuation
Balance is the other
I intend this to be in a carbon stock
