Page 2 - JSB Redesigned Monster Reviews

I like JSB for their consistency and quality.

Make the skirt diameter smaller. Consistently measures 4.81mm diameter. Couldn't close the barrel without nicking the o-ring.

I have a Gamo 1300 fps break barrel and these pellets did not fit. I forced a couple into the barrel by tapping them in with a small punch and they shot just ok. If you have a bore on the larger side, these pellets may be great for you. Fortunately I bought them from Pyramid Air and their customer service took care of me as i was not able to use them. I was not expecting that, again, great job guys and thank you.

consistency & weight.

Would like to see a screw on lid for can.

These pellets are long and since I use single shot rifles for competitions I don't know if they'd work for magazines.
I have yet to put them on paper so I'm not sure how they'll perform at 50 yard ranges. Right now I'm doing selection testing indoors to see which of several pellets are the most consistent in my several PCP rifles.

Grouping is smaller than older version

Must use a pellet set with Gamo mach 1. Old style looks smoother on surface of pellet.

Old style are easier to load.Pellets are to tight for Gamo mach1

Accurate through my Mrod.

These are very hard to load into the magazine and subsequently to chamber. I actually have to use a pencil tip to get them to seat into the magazine. At first I thought it was my magazine and I grabbed a different one. Nope. Not sure where they are hanging up, but I suspect the head is too large. I have ordered the original design Jumbo Monsters and hope they will feed easier. Too bad. They are very accurate through my barrel.

May have difficulty chambering them depending on your rifle.

Very well made as usual for JSB. Much better performance out of several rifles including rifles that didn't shoot the originals well at all. Might be my new go to pellet for field target if I can keep them under 20 ft lbs.

Like everyone else I would enjoy receiving more for the same money. And a free rifle with purchase of pellets while we're dreaming

From limited testing I can see the improvements to these pellets over the originals. Heavy pellets that fly straight are a win in my book. I'm thinking these will give great results when I can stretch the distance beyond 50 yards. No spiraling or wag evident at 50 or less.

new design is great. my rifle likes them

I'd rather they be more weight consistant. Onlly ablut 1/3 are within .40 grains either way 1/3 are heavier with weight ukp to an additional1.00 grains and the lighter third ranging and additional lighter amount of up to .25 grains

I wash and lub before I weight sepperate.

New shape has better aerodynamics...better ballistic coefficient. Sorted pellets are more accurate both in calm air and wind. Old design had mold seams on most pellets. New design pellets are smooth. Little if any skirt damage. After a weight sort I air gauged approximately 7 tins and found a relative narrow distribution of head size around 4.520mm. Old design had much larger head size distribution.

All 12 tins were weight sorted. Weight varied between 835mg and 905mg and I culled about 5 tins. These are expensive tins of only 400 pellets, so poor weight control is very costly. Better quality control for weight would make this pellet more appealing.

Generally, weight variation does increase with heavier pellets and the old design varied even more. Shooters willing to weight sort will be rewarded with batches that have similar head size...at least until the molds start showing some use. How much time and money for accurate pellets is always the question. The new Monsters might be your answer.

These are so much better than the original Monsters that it is not difficult to image why JSB did the redesign. There is a significant improvement in accuracy in all my rifles that like JSB's.

Nothing

They did benefit from washing and relubing when I used them for field target in a Steyr.

Really nothing. I have had excellent results using other JSB Exact pellets. These Redesigned Monster 13.43 grain pellets may be a good product when used in a high power air rifle, but I could not get them to group at all in my professionally tuned Weihrauch HW30S rifle that averages 678 fps, FPE 8.1 lbs. and groups nicely with JSB Exact Match Express 7.87 grain pellets.

Pellet skirt diameter appears too large for HW30S chamber. The pellet skirt protruded slightly from the mouth of the chamber even when pressed upon firmly with finger. No pellets hung up in the barrel when fired but the grouping was wildly scattered. When the pellet was pressed upon firmly with seating tool it did not seat flush with chamber mouth. Excessive force was not used in any attempt to seat the pellet.

My tuned HW30S groups nicely with JSB Exact Match Express 7.87 grains as mentioned above: 10 shots inside 3/4" at 10 M. during same shooting session when the Redesigned Monsters splattered over a 3 inch area. It also groups very well with JSB Exact Match 8.44 grains, RWS R-10 7.0 grains and just OK with JSB Exact 7.33 grains. Although I have done a lot of shooting over the past 70 years, I am new to springer air guns with only slightly more than 300 rounds fired through my HW30S, a rifle I have learned to love in a very short time !! I look forward to seeing some more reviews by others using this pellet and also whether or not these Redesigned Monsters shoot well in high powered air rifles ??
