I bet if you get a new truflite cut to 6x45 the first components you try will shoot 3/4 and you can just get on with it, neck shooting fallow at 200m, small goats bullet well placed in the chest, turkeys, body shots on south island wallabies, any rabbit or hare will be history.
Nice hear your bench test setup. Sounds great.
Defo. Whilst the bush thing probably doesn't have any negative impacts if done properly, clearly something is negatively impacting the groups so that's got to be near the top of the list of likely culprits.Quote:

Bit of an update on this. After a bit of a break, I sourced and loaded up some 70gr ballistic tips with BM8208 in Win cases. I had a good feeling about the combo, because these bullets had shot well in a previous 6x45, and the throat/seating depth/mag length/case capacity was just perfect. Like it was designed to go together….
Results were also very pleasing.

Very happy with the accuracy, and the velocity is bang on for an 18” barrel. Pressure is up there but not too hot, so cases will last.
Reviving an old thread….
Turns out that the groups above were a bit of a ‘flash in the pan’ and I’ve still struggled to get consistent results.
So during lockdown, I set about proving a theory I had. That theory was that there is nothing wrong with the hardware, it was the software that was causing problems. In other words, I can’t shoot for sh*t! So I set about building a purpose built benchrest stock for the wee BSA, in order to remove my influence as much as possible. I had a hunch that the narrow light standard stock was feeling the influence of any change in hand pressure, torque through the pistol grip, and the steep rise from toe to grip cap was partial to creating vertical groups under recoil. I wanted a stock that would recoil straight back, have a wide flat forend to ride the sandbags better and a more vertical pistol grip with palm swell.
So a couple of months later, this is what I produced. Built the old school way with chisels, gouges, scrapers and some inletting black.

Was my theory correct? Well, I think it was. I found the rifle a lot ‘nicer’ to shoot, recoiling straight back creating a much more satisfactory follow through from the shot. I tested 4 different projectiles with the following results:
80gr Speer SP 26.5gr 2206h average 18mm
70gr Ballistic Tip 26.3gr BM8208 average 25mm
100gr Core Lokt 24gr 2206H average 22mm
85gr HPBT 26.1gr BM8208 average 22mm
Best of all, there was no large variance across groups like I had been finding in the sporter stock. Do you sum it all up, I’ve proven that shooting a svelte, light walkabout hunting rifle isn’t that easy. Technique is everything, and now I know that the rifle is ok, I’ve got a lot of work yo do sorting out my shooting technique.
Yeah sure do, looks a little like:Quote:

Hi Hunter_Nick, I have a 6x45 on a Sako A1, that shoots superbly with anything fed from 55gns to 100gns. The 6x45 is an unsung cartridge and I can't figure out why it has not been commercialised. The likelihood that your 6x45 is a dud is very low as the 6x45 is an inherently accurate cartridge.Quote:

It produced 2 to 4 inch groups, with a occasional 1 inch group randomly delivered. It was put together by Alan Carr, and he knows how to put together a rifle. He tried different bullets, powers, loads, I shot it, it was re-bedded, the scope was swapped out, it was just not shooting. He was talking about unscrewing the barrel hat owed him nearly $2k for another! He believed he had an inexplicable dud.
as a last try he swapped his scope and mounts off for one off his other BSA rifles and voila it was a 0.5" to 1" shooter. It was the mounts! and when the dud mounts were put on a different BSA rifle that rifle shot well. Duh?
The BSA Hunter action is rock solid, at the same quality of a Sako anytime. The new barrel is likely to be great as well. I have 2 BSAs, my friend has 4, and they all shoot very well.
The point is - look at everything. If you've tried lots of loads then that is unlikely to be the problem. Is it bedded? Have you tried someone else shooting it? Swap the scope for another. Try different mounts. BTW the BSA scope mounts by SportsMatch are good, and any mounts that fit the CZ550 will fit the BSA.
Also try a different shooting set up, I have recently got the top of the line Caldwells BenchRest and my groups went down in size. You don't have to spend a fortune, do what you can to give yourself the best possible shooting position. Use a rear bag and decent front rest. Get someone you know or in the club to shoot it off their fancy rage bags.
Don't give up. I'm happy to share my 6x45 loads with you, just PM me. The 6x45 is a real treat when its working, once you get it shooting you'll love it.
Well, finally cracked the code and have the 6x45 performing as it should be. Fast and accurate.
Shot a couple of groups working up a new load, and both easily 1/2 MOA with this one making 0.3 MOA.
Accuracy has come on as pressure increased. Caution with this load, as it’s safe in my rifle but over book max.
