Not to get even more off topic, but ive read that with standard lg .22 ammo, hollow points rarely open up, and you get better results with round nose ammo.  I know its a pellet, so not sure how much difference it will make.

Ive had good sucess with varmit control with the hollow point.  Never used a pointed to take varmit yet.  I have shot soft targets with the hp and it does expand if you can imaginr a .22 mushrooms.   I have shot long distance targets with pointed and like the accuracy results.   All with beeman pellets

Good topic...

Got an old Benjy 347 model .177 pump from my dad... Maybe from early 70's???

Never took apart an air rifle... No hold air... Is it seals or o-rings?

Would this be easy to just take apart and match up/change seals or o-rings?

Appreciate the input....

I wonder if you can use their coupons since its not a firearm. 

Indeed you can use the coupon.  I recently got my Christmas present of a Benjamin Trail Nitro .22 with the 25% off coupon.  Comes with a decent AO scope.  Fun gun, not nearly as loud as other pellet rifles.  Smacks right through 1/2" plywood as I found attempting to build a pellet trap.

I recently researched the disassebly and repair of my old Beeman/RWS/Diana recoiless pistol to replace seals.  Quite a project.  Came across a guy that does airgun repair you may want to contact if you decide not to source the parts and do it yourself:

"Randall Bimrose"  barrelbender@charter.net does all sort of airgun repair and can give you a quote.

 I have a few links for airgun parts if you need them.  Ended up getting the right piston seals from England.

My gun was unique and would have been lost without instructions, so that should be the first task beside finding seals.  Lot of older guns used organic (leather) for seals and did not last well especially if someone used petroleum oil on them.

Is he on island?
Ive made the mistake of shooting through plywood too with 10 pumps on my benj and pointed pellets.   Kinda cool for a supposedly a 700-800 fps entry level .22 pellet gun.

Randy in in SoCal unfortunately.  Sucks, I hate shipping stuff.

I was going to have the Barrel Bender guy do my old single break Walther, but ended up selling it instead. Note to self, don't sell any more stuff. You will regret it.
This was a while ago, but he may still be a viable entity. Probably the answer for the more exotic stuff. As I recall he was on the left coast so shipping was not as big a deal.
For the old Benjiman and Sheridan, K3014's lead was a good one.
Guys name is Jon. He has all the tools and skills to do them. Factory trained while at Honolulu Sporting Goods in Ala Moana.
Anybody but me old enough to remember them???
With his permission Ph. 262-8364.
I will be seeing him next week.

some of us are young enough to remember honsports

Nice let us know how it goes.  Im sure ill need his services in the future

Chee! I hope it works out for you. Aloha

I love hollow points in my crosman quest .22.  RWS HP or Beeman crow magnum.  the beemans are little heavier but effect is about the same.
my crosman quest is rated at 800 fps.
the hollow points make a difference, but gotta have some velocity to open them up some. with my weaker benjamin handgun it doesnt open up at all.
this is what it does to cans filled with water.

Heck
I just been shooting empty cans.
Hadn't thought about filling 'em with water.
Mine works good for the occasional rat or mouse in the chicken feed and the garden.
Not as guaranteed  as traps but waaaay more fun.
Have a Chrony also. I guess I could see how fast it really is

I was thinking of making ballistics jello test but calculated that it would take a lot of jello and would not be worth it for hollow point pellets.

i heard clay is a good substitute.
