Benjamin Benjamin Bulldog M357 Impression

Have you tried the 156 gr slugs from pro slugs? I'm thinking about ordering a big box of 500 for $120 plus shipping.
@bearair I have not, but if you do please let us know so I can be on the lookout for your assessment of their performance out of your Bulldog.
I bought 500 of those ProSlug 156 grain HP-BT slugs a while back. These are great shooters, especially at long distances where they had tight close-to moa sized groups. The football shape makes them fly extremely well with no tumbling over the apex. These are the best grouping "production" slugs currently on the market for me.

Testing some .357 hollow-point, flat-base, roughly 125 grain slugs made in a Corbin S Press.

This scale isn't the best. I've had it 24 hours and it fluctuates already. It seems that bluetooth or wifi signals may affect it. When I move the phone close to it it starts fluctuating the reading. When it sat between my phone and the chronograph it fluctuated at random. I may have to take it back.

I shot tethered at 2900 psi. The external reg read 2800 psi.

The M357 manometer read 2900 psi.

The setup.

They are actual .357s and fed into the breech nicely. Not too loose, not too tight.

These slugs shot well from 50 yards this group was approximately 1.75" CTC.

Shot string data for the above target. These were between 124-125 grain, but the app doesn't accept decimals.

One thing I can add is this - using earmuffs (like the orange pair pictured) messes up my cheek weld. They interfere with making the most contact between my face and the top of the rifle stock. Ear plugs work much better. The M357 is still slinging a lot of the lead that I throw at it. Good times.
