    I would like to experiment with a sampling of larger head diameter .22 pellets. My Crosman and JSB 14.3 gr. measure .215-.216  Are such oversize pellets available?

    Spend some time reviewing the H&N line of pellets.  They make a number of pellets like you are looking for.   You can usually find them on sale at Field Supply.

    Thanks for the help, socaloldman.  I have five tins of the H&N oversize .22 in both weights on the way from Field Supply.  $48.00 delivered.  Had to use the calculator to convert to English diameter size.  I have a RWS 34 with a looser breech fit I am looking to improve accuracy in.

    IF your barrel is similar to Walther then there might be an issue. See JSB's primarily make pellets that feed well in FX. I am into the development of Custom pellet swaging moulds and with the help of articles of Bob (Rsterne), Sub and Dark charisma I made an interesting discovery. The pellet in the front is JSB and the barrel is modelled after L Walther. rest 2 are the pellets that can be made from the mould which will be commercially available. 

     

    You see, the pellet doesnt engage the rifling, the model is not a .22 cal, but you know what can be the issue with smaller pellets.

    Thank you for the interesting information. I have no idea if the RWS 34 .22 barrel is modeled off a Walther design.  My issues as has been reported here in another title is my mentioned pellets drop into the breech below flush simply by gravity. This is a new production rifle. They will fall out if gun turned pellet down. I have been tamping them in lightly with a rounded wood golf pin. Several times I nearly fired the gun without a pellet seeing it on the ground at my feet. I get more flyers than I can account for.  I have a RWS warranty return authorization for them to look at it. My old RWS 34 .22 requires a light engraving press fit and shoots extremely well with these pellets. Trouble is RWS says I must send a return postage check of $30. to get gun or replacement gun back.  If the gun is found to be within their specs for accuracy they will charge me an additional $35. range test fee. Now I know what a limited warranty means. They will not sell me a spare part barrel. I figured I would give the larger pellets a try before returning the gun.

    The new barrel is choked but the 2004 year one I think is not choked. I swapped barrels and now have the old very accurate barrel on the new 34. Shoots great with perfect fit and function.  I am tempted to just keep it without returning it for a check up. Think of all the spare parts I have with little invested in the new gun. If the pellet test is successful problem solved. H&N's will be added to the ammo inventory.

    Does this make sense?

    In addition to the larger head sizes 5.54 and 5.55 of the H&N FTTs I might suggest trying the Crosman Pointed which come in tins of 175 which I noticed fit tighter than the domed Crosmans and had good accuracy in the 22 springers I used them in.

    I have bought mostly 5.52 H&N's for several different airguns, however upon checking with a PelletGage, I find that most are even larger then 'advertised' so I might recommend to you to check the diameter of the experimental pellets that you use to verify the size.  There also are smaller diameter pellets within the 5.52 tin, so that would lead you to believe that the gun didn't like 5.52 when that would be a false reading.

    Yes, I do plan on sorting sizes in each tin to get two dozen of each size for initial testing.  I just finished slugging the bores of both guns using a Dewey .22 rod and jag. Barrels gripped in soft jaws on my vice.  I was wrong, the older 34 is choked, too.  The pictures show the seating depth difference in both guns. I put the new barrel on the old 34 for testing purposes. The Vortek scope will be moved to it also. The Crosman 14.3's measure at .216 dia. before slugging. The choked section of the bores is approx. 1.6 inches in length.  Pellets measure right at .214 dia. after slugging for both guns. Again, my reason for oversize pellet testing is for a better breech hold of pellet and hopefully reducing the unexplained flyers. With any luck I will have that and the decent accuracy the gun delivers as a whole.

    The five sample tins of HN's arrived an hour ago. Got to shoot 15 each at 15 yards of the 14.6 gr. FTT before sun went down. Used 5.53, .54 and .55 with open sights off hand. The fit in the looser breech 34 was what I was hoping for.   The accuracy?……WOW.  Looking forward to shooting them and the 21.gr. Barracudas with the Vortex in place tomorrow. Reminds me of the accuracy I got with .177 Meisterkugelns in my FWB 124 years ago. I can tell right now there will be no need to send the gun in to Umerex.

    I had time this morning to run an accuracy test with the HN pellets. Clearly these pellets are a cut WAY above the Crosman variety. But, my older barrel likes the Crosman plenty good enough for the price point. Cheap practice and fun.  Both guns were tested from 70 feet rested, same un adjusted Vortex scope left at 4x.  50 F and zero wind. I chose to pull direct from the cans instead of pre measuring any. Both guns have their preferences but overall they all shot extremely well.  I will be stocking up on few more cans of the HN's soon. Still need to get another scope on the older 34, no plans right now to switch barrels back. The new gun with older barrel went right back to hitting the 100 yd. saw blade with Crosmans with no tinkering of adjustments. That mount is solid.  The photo with note shows 12 shots of how the loose fitting Crosmans were throwing unexplained flyers all the time. A couple barely on steel. The rifle will not be returning for a checkup.
