3160 FPS with a 105gr bullet and a Dasher is INSANE over-pressure and is very dangerous.

I just discussed this with a past 600-yard IBS shooter of the year and his comment was "I run in the mid-2900s and even 3050 fps is very extreme"

Honestly I do not know if the person who posted that was serious but his numbers are way out of the extreme pressure range and I cannot allow this to be recommended to our readers.

Accordingly, the post will be annotated for Safety and poster savagedasher has been banned from this board forever.

I run a Dasher with 110 Sierra's at 2915fps. 27" barrel, 34gr of RL16, by just using a drop funnel my bullet is into powder, short freebore. I do not have a way to measure pressure generated, but honestly feel I am at low pressures. Last time I shot, with all involved cold, 30 deg, my last 2 shots gassed my chamber, no seal off. I can add up to .5gr and still achieve bullet hold, I am going to add .2gr and shoot this weekend.
OP, I would try a different powder, or more of what you are using. H4350 and IMR 4451 are solid performers, but IMO not performance powders.

Yes t 105 hb

Have you checked this on 2 crony or only one, sounds improbable and unsafe.

The second Dasher I shot had a .237 Bore, the reamer had a .155 freebore and I was shooting the Berger 105 VLDs. I used VV N540, which contains a considerable amount of Nitro to boost energy / velocity. With 33.0grs of N540 and a 30" barrel, my load was going 3070f.p.s. with no discernible effects of excessive pressure. The accuracy with that load was fantastic! However, the downside was considerable too! I got a whopping 1600 rounds of accurate barrel life! There is a saying and it is true: "You WILL pay for performance and there is no way around it"!

Jesus, we lost savagedasher. Forumboss does not play.

I’m glad he said something though. I just got a 6 Dasher, and I am learning the basics about it. I’m fine with 2,900 FPS. No need to mess up a gun or yourself.

Bottom line here.

ANY member who posts seriously dangerous load information will be banned
Immediately and PERMANENTLY.

There will be no discussion, no hand-holding.

And rest assured I will do everything I can to make sure these individuals never come back (yes we trace their IPs and can determine their residential addresses).
