John, Ordered pellets from Straight Shooters. If UPS delivers them today, it will be about a 10 day turn around. List follows:B-3088 Silver Arrow 22 - $8.35Ordered: 2Shipped: 2B-3250 Kodiak 22 - $7.60Ordered: 4Shipped: 4B-33060 Silver Ace 22 - $10.60Ordered: 2Shipped: 2JSB-Exact-22-Hvy JSB Exact 22 Heavy - $15.00Ordered: 2Shipped: 2JSB-Exact-22 Exact 22 - $9.75Ordered: 2Shipped: 2JSB-Predator-22 JSB Predator Pellets .22 - $11.75Ordered: 2Shipped: 2Basically, I concentrated on the heavier pellets as they seem to work best in the Sumatra. Also likes the ones with the extra rings just back of the dome.

That looks like a good mix of pellets. I'm sure you'll find at least one that your gun really likes.

Re Predators...I've read much on different forums and user comments are very useful...one characteristic about these pellets that stands out is the damage they do at impact...seems they tear up bone/flesh whereas domes penetrate better in contrast without as much damage....but accuracy still is debated...it may be the differences in power (FPS) that affect accuracy...or the points are not exactly centered....thus causing some flyers...???One thing I would suggest is compare the Predator .22 cal skirt diameter to that of the JSB .22's.....I found the JSB skirt diameters larger than Crosman Premiers for instance......(The JSB's fit tighter in the breech....and were more accurate)..I have not found yet what the predator skirt diameters are yet....

The one predator pellet I have left measures .224". Which corresponds very closely to other JSB pellets listed on Straight Shooters website.Link to Straight Shooters Pellet Comparison TableThey don't have the Predator in their table listing.

Ok...that is a plus....(I use SS pellet compaison occasionally)....flyers could then be weight differences...or the pointed end not centered exactly...but also, high FPS could send them off trajectory.. on my next pellet order,I'll get some and test in both my 22's....(Springer,PCP)...

Managed to accomplish my final goal in the Sumatra project. After all, squirrel shooting and other small game hunting was my objective. OrneryOlMoFo357 invited me on a coyote/squirrel workout and I brought the Sumatra and a tank for the squirrels. Probably some of you have questioned the use of an airgun alongside firearms on a CA ground squirrel colony. After all, the range gets out past 200 yds pretty quickly and an airgun does limit your range compared to a 223.We went to a ridge that offered 360 degree squirrel shooting and the evolution started slowly as these squirrels knew the license plates on the Suburban and Bronco. :D I practiced on small rocks while Ornery worked on his long range shots. Then a few squirrels started showing up and and were lased at acceptable, but long ranges. One guy kept showing up and the shots threw dirt on it but, didn't connect at the 70 yd range. So the rock shooting continued, while working on where to hold. Then the 70 yd squirrel appeared and was standing up like a picket pin. The Sumatra cracked and down went the squirrel!

post-16-1231699818_thumb.jpgHere's the pic of Sumatra's first blood. The shot was taken from a folding bench.post-16-1231699831_thumb.jpgA little wound detail. Didn't actually find the entrance & exit holes.post-16-1231699730_thumb.jpgHere's the traditional trophy pose. <_<

Being pleased with the gun at this point I put it away and dragged out the powder guns. NOT!! Of course I continued air gunning, they were coming out for their afternoon feeding and I had some sight data fresh in my head. Next was a 35 yd shot that had a lot of luck involved. Took the shot while leaning against a tree and ricocheted into the squirrel.

Continuing with the Sumatra, I got the shooting sticks out and started working a patch of squirrels that were out at about 80 - 150 yds. This seemed to be a good place to give the gun a good long range workout. Tried a 93 yard shot, with about 18" of holdover, and it resulted in a great acrobatic show starting with a 12" leap straight up and a 360 back flip. No blood and the squirrel didn't give me a second chance. Doubled the holdover on a 120 yd shot and hit about two feet low. Decided it would be better to hit another one, rather than keep doing these hail mary shots. :D Laser said 83, that seemed reasonable. Increased the holdover from the 70 yd shot and let fly. Apparently a midbody spine shot, the squirrel started doing a front leg crawl. Squirrel stopped about a foot from a hole and the third shot seemed to be a chest cavity hit. Yes there was a miss between one and three. :D Squirrel seems to be anchored and dying, with the fourth shot it waved a goodbye and laid it's head down. This seems to tell me that I need a mildot scope to take some of the guess work out of this airgun squirrel sniping.

post-16-1231702296_thumb.jpgThe funny color is probably due to the cell phone battery being on it's last legs and/or the low angle of the sun. With three hits on this squirrel there was no visible blood.

Additional Details:The pellet used on this expedition was the Eun Jin 28 gr Dome. It seems to be high on the Sumatra's favored list. Using a ballistic program show that the 35 yd shot was 844 fps with 44 fpe, the 70 yd shot was 758 fps with 36 fpe and the 83 yd shot was 730 fps with 33 fpe. The 35 yd shot should require a hold under of .6", the 70 shot a hold over of 3.1" and the 83 yd shot a hold over of 5.4" according to the ballistic program.

Gary I'm glad to see you got some blood and real world testing done with your NEW gun. Great pictures and description as I would expect from you. Those pellets put the hurt on those guys. I would agree a mildot is indeed a great help for the longer shots as guessing just isn't always an option. Thanks for sharing it sounded like a fun time.

Good shooting...!! I did same thing (shooting rocks in field for reference untill I got the Mil Dot scope).Now,shooting with the Mil Dot has made longer shots much easier. (I tape a range card to my stock for quick reference.) I'm working on a card that will compensate for inclines to 30 degrees....a quick way around that is knowing vertical height of target above your shooting position...just subtract that from your lasered range for actual range (trajectory)......works on either up or down inclines..Example: Disco .22 (This works for level shots out to 70 yards)Turkey032.jpg

The 6.5 - 20X Simmons Whitetail Classic Mil Dot. It's on perpetual sale at MidWay & works well for me. The scope has the Mil Dot reticle in the second focal plane as most of the cheaper scope seem to do.
