Help!

[capture]

Has anyone found that retumbo is the best or RL 25 I've tried both and can't get any kind of a group! I'm shooting with a silencer also maybe that has something to do with it but the manufacturer said it would improve accuracy?
Anyone else have any ideas or a good starting point for a load?

I've tried Retumbo from 102-113 grains no accuracy
Also RL 25 from 96-98 grains no accuracy
Oal 3.648
185 Bergers

Any advice would be very appreciated!
Thanks!

What caliber, rifle set up, twist rate etc.

It's a Weatherby Accumark1 and 10 twist
26 inch barrel

Without cartridge it's hard to say for sure but I am wondering if you may be to hot.

308, 300 win mag, 338wm or 338 lapua?

A good start would be whether the rifle is known to be accurate?

I'm sorry it's a 30-378 weatherby!

Windtech1 posted in another thread he got .5moa with 110 Gr retumbo.

Use the google search button at top right to search using key words.

I found Windtech1 post by searching 30-378 Berger 185

Capture, many are getting best groups with the 210 or 215 Bergers. Most are using H1000 with them.

You should try the 200grn accubond, 210 berger vld, or 215/230 Berger hybrid. Retumbo for the 200-215, RL33, VV N570, H50bmg, or US869 for the 230s. You may be having jacket distortion and or bullet blow up pushing 185s really fast in a 10 twist.

try 200 grn bullets, IMR7828, mag primer and remove the suppressor.
if that gives you good accuracy install the suppressor and try again
