Stock 1377 and heavy pellets

[CO2Freak]

I want to shoot my 1377 with heavy pellets, like RWS Super Mags or JSB Heavies.

Before it buy a tin, can you please share your experiences with shooting heavy pellets with a stock 1377... For springers it is not advised, but I reckon this might be different for pumpers.

Looks like an ultimate plinking combi to me !

It won't hurt anything, but they'll be slow

Buy 'em & don't regret it.  Sometimes the (tighter) groups surprise you.

[bgmcgee]

Can't hurt. Like T says they might surprise ya.

I've shot many different pellets of various weights through my 1377, whatever I happened to have.  Never had a problem.  I was shooting it tonight using 3 different pellets; it liked H&N Match (rifle).  RC

I have shot the Ultra Mags without any problems. Grouped well 


Oh, and for springers, you should use a nice heavy pellet. I think its worse to use to light of a pellet in a springer??

Generally, I agree, though much depends on the power of the gun what is considered light.  I wouldn't think that chasing after fps by using x-light pellets is good for any springer.  RC

My 1377 is no longer stock, but it did well with JSB Exact Heavies. You can get the JSB sampler pack and try a few weights. I use Exacts exclusively now, but used to shoot the Heavies and even the Monsters. The improved BC partially compensates for the lower muzzle velocity.

Mine stock liked the  Winchester pointed best accuracy wise...


Now I am working on a 1377 carbine with a MK177 pump tube in hopes of launching  JSB Beasts at about 700 fps thru a Daisy 953 1:15 barrel...

I should get about 900+ fps with 7.9g CPL with the 19" L.W.  1:17.7 barrel

I will be using a Crosman 1:16  barrel also...

i just shot 20 yards with a stock set up 1377 15 pumps seemed like it took forever for the 10 grain pellet to hit the target

I think I have a few CP heavies 10.4 grain domes left from the pellet exchange that I can shoot over the chrony. I can hopefully get to it today and post the results next to CP lights that I already shot over the chrony. My internals are stock, but I have a 24" barrel. If nothing else, it will somewhat show the difference in speed.


Now let's hope the rain stays away!

Not so bad on a 1377 since it shoots faster. If you had a 1322 and used heavy pellets you'd definitely be able to see them as they fly towards the target.

Can not speak for the 1377, Though in 2289/1322's I have used heavy pellets a good bit and they are great.

Here is a 13 g pellet form my 1377 carbine...



I like heavies too!
