Does this sound reasonable scoring a new Pellet

Hello everyone,

Hope I can make my point and make sense. Here is the deal, I am trying out a “new” Pellet to shoot in my FX Crown MK II rifle. By new I mean this is new to this rifle, I have been shooting JSB MRD 13.43, and I now have shot a full tin ( 400 ) with the Crown. I feel that the rifle is seasoned ( if that is possible ) to the FX Pellet and now is a good test to confirm weather or not that “the Pellet” is accurate. Now let me say that I know for a fact that the rifle is accurate, so any scoring will be on the Pellet less the human factor.

Now look at the attached photo of a 25-Yard MOA target that I shot this morning, conditions near perfect, overcast sky, absolutely no wind and cool temp of 48 degrees. Also note that I used my eye patch while shooting this target. On #4 I have circled it in Blue, I will accept that this miss is on me ( the human factor ). On #5 I circled it in Red and here comes the hard part to consider and explain. I am not bragging but generally I do not miss by that much, so is this a Pellet flier or is it me, OR is it a combination??? Number 6, 17, 24 and 25, again I will accept as a miss caused by me. If I use a .177 Scoring Plug, then #6 and #25 are MOA. On #10, #21 and #22 circled in Red, I am calling these Fliers, but are they???

When you fellows are fine tuning your guns to a Pellet, how critical do you look at and score each shot? I would truly appreciate a fair and sincere response about your procedure.

Thank you,
ThomasT

I agree. You really need to spend some time with a particular pellet to get it dialed in. This could be barrel harmonics or any number of things that cause a pellet to not exit as consistently for a given tune. That is why finding the "magic pellet" is so important using springers as you don't have the ability to dial the pellet in, so you have to change pellets to find what that power plant/barrel/etc. likes.

Anyway, my $0.02

Thomas, If it were me, I would just stick with the JSB Redesigns...seen your outstanding groups with them thru your Crown before, your barrel definitely prefers them where it is tuned right now! You might have to adjust speed with this newer pellet....
Hello @Ranchibi

You are most likely 100% correct, but my poor ole wore out brain just cannot have un-answered questions running around it there o_O . Yes I bumped it up to 907 ( actually above 910 ) and it did shoot a tad better. At 868 /870 I am able to shoot both the JSB and the FX. Really what I am looking for is a pellet that has the fewest fliers and the one that "misses" the closest to the bulls eye :D.

Hello @Motorhead

I am shooting at 870 fps for the last 200 rounds. I have shot at 907 down to 868, and 907 was the best overall results.

I agree, those look like "fliers". Although there are those on here (AGN that will tell you it's NEVER the pellet and ALWAYS the barrel)... Not that I agree, but it's one of the theories on AGN. Are the FX 13.4s a similar shape to the RDMs, or are they a similar (barrel type) shape to the JSB Original Monsters?

Hello @Centercut

Yes, they have the center portion shape of a barrel with just a small skirt at the bottom. The profile is very close to the Original JSB. I am glad that you stated it that way about the barrel, to me it is too inconsistent to be a problem with the barrel. Also I did not state but I am not using a moderator.

Yes, so those pellets are a different shape than the Monster RDs, correct? That explains to me why you are getting those flyers. The original Monsters have a looser fit than the RDMs in the STX barrel. I shoot the RDMs at 820 FPS for FT (500mm STX Superior) and it is VERY accurate...

Hello again Centercut,

Very close to the original and they are a bit tighter when I put them into the magazine. The JSB MRD normally will just fall into the slots on the magazine, but the FX does not. I actually have to slightly push some of them down with my thumb nail. I can also feel the difference when I insert a pellet into the chamber. On the tin they show to be 4.52mm.

Gotcha. IMHO, the "barrel" shaped Original Monsters just don't shoot as well in the Superior liner as the RD Monsters. My barrel shoots the Original about 10 to 15 fps faster than the RD Monsters, and also allows some flyers every now and then. No flyers with the .177 RDMs (I only wish that were true for the .22 RDMs).

IME, The size printed on the tin can not be trusted. I just sorted 5 tins of JSBs marked 5.51 and about 1/2 were 5.53 and the other half were 5.54. Out of those 5 tins there were only TWO pellets that were under 5.52 and none were over 5.54.

Hello @igolfat8

Wow, well they were close :oops: . It is crazy what we pay for now days and what we actually receive. I do not have a sorter so I have no idea what is actually in the tin. I must say this, The FX pellets do look ( appearance ) good in overall quality. I have lots of tin of the JSB MRD 13.43 so I will "clean" my barrel with some of those.

My experience exactly! I have not gotten true to label weight or head size out of JSB in last couple years.

Thomas, my advice to you if you care about precision shooting is to buy a head size sorter (pelletgage.com) and a scale that will weigh to hundredths of a grain. These are not very expensive and will make all the difference in your shooting results.

I have been borrowing an FX Impact M3 with a 500mm 22 Cal barrel (Not sure what liner it has) for a while and had never seen an uncalled flyer using FX or JSB Jumbo Hvy and Monster Redesigns. It shoots CPHPs extremely well too, but there is almost always a flyer or two every 20 shots with the CPHP. Not so with the JSB/FX.

Then the flyers started showing up. Nothing was changed on the rifle. Barrel had been cleaned about 50 shots ago, but cleaning never did impact accuracy before anyway, other than maybe the first 3 shots. Now, I am getting flyers every 10 to 15 shots without fail. No explanation that I can come up with. Same tin of pellets, same gun, same settings, same scope, everything is tight.....maybe the air molecules have changed somehow or Chandler Wobble has become more erratic or more severe of late! :unsure:

Hello @rsfrid

I have a digital scale so I need to order a gauge.
