If your rifle likes Varget, by all means, let it eat. I've had good results with Varget. The RL powders give me equal precision with more velocity options and lower pressures. The latter leads to better brass and barrel life.
And Lapua also has brass now. No waiting for 6 br and 6 gt. Used both. Br solid good to go. 6 gt been using lately and I’ve switched over to it for now 600/1000 FB am very happy with it. Small groups and easy to load just like 6 br is.
this!
No. I kinda did this. Neck length will be wrong as you are feeding the reamer in farther which includes the neck yet the neck on your brass does not change.
I built a 6br on a Tikka 595. With the 22-250 magazine it feeds great, much as your observing with the Sako S90. This was before the AICS magazine conversion for the BR length cartridges. If you go the Dasher route make sure you/your gun smith uses a reamer that will work with the brass you plan on using and that the die functions with that chanber and brass. As a wildcat not all dies and reamers work well together. The 6 BR is the easy button but I sure like my Dasher built on an Origin action and Proof pre-fit barrels. Currently I'm using Alpha Dasher brass and it seems to work OK in the pre-fit proof and resizing with a Wilson FLS bushing die. I'm not running the Dasher hard but it's nice to have the extra case capacity so you can use powders other than Varget and Precision.
I'am not a gunsmith or high level targte shooter but if someone asked me the most important fator is the skill level of the smith and attention to all the small details that go into building and shooting a extremly accurate rifle
I shot a 6mm Rem for 40 years. It's a barrel burner. Not known for accuracy. Don't know if you can find brass. I now own a 6BR and a 6BRX. Any load is very accurate for varmint hunting. 4000 rounds on my 6BR it still shoots small. The 6BRX duplicates Dasher speed. Just FF a 6BR case any load to makea 6BRX.
You can order 10 reamers of the same spec and they wont all shoot the same. Its not just about the spec but the actual chamber they cut. Variation in reamers causes this. Its easier for a gunsmith to identify a really good reamer because you see it doing exceptional across a lot of barrels. If you or someone you know always seems to get really good barrels thats also a sign.
That right there is pure Gold!
Alex, Guess it comes under the same heading as a “Hummer Barrel”. No rhyme or reason, just dumb luck!
Can it also be the interaction between the reamer and the specific barrel? I imagine each barrel is slightly different even if the reamers were identical. It would be interesting to see the same barrel blank chambered with both reamers.
