Ruger Precision Rifle - Single-digit ES?

[Homerange]

in saying that, all of my single digit strings were shot in 2017 with H4350, but now that that powder has been banned in the UK, I'm not confident that I'd be able to repeat those results with the powders that are available now.

Why ? Is ADI 2209 still available ? < same stuff.

Single digit ES for a three shot group IS NOT IMPRESSIVE. Shoot a 20 shot group and then tell me you have a single digit ES and my first question is let’s see it done live on video, so you can’t delete shots.

I know that Dave and you missed the whole point of my post.

Thank you for sharing. Are you using a suppressor, or the standard muzzle brake?

I have a gen I with the A419 brake on it.

For reference, these are the numbers with some H4350 loads I had lying around for a few years, and did and proper loading for (which I don't bother with for this rifle anymore)

This is pretty standard out of my 6.5cm RPR with 2k+ rounds through it. Never seen single digit ES

This is what I got with my RPR with not so good powder and minimum loading. 2300 rounds on the barrel & hasn't been treated well.

This is absolute bare minimum loading:
•Lapua SRP brass
•CCI 450
•AA4350 powder (not optimal powder)
•136 lapua scenars
•anneal every 3 or so
•loading for this round is very basic: size with bushing, trim, prime, powder/seat

When I get around to it, I'll be using Hornady brass next

Other than the brass, this should be as bad as it gets with this rifle

Proving my point that your ES on 20+ shot strings will be approximately 4 times the SD.

Muzzle brake or suppressor should not significantly affect the ES or SD of the bullets, the gases are not affected until after the bullet has left the barrel.
