Heavy Hammer and/or Heavy spring for High Power?
Hi guys,
I’m preparing my Condor for high power competition this weekend, I’ve just fitted a 103gr brass hammer and filled the bottle to 2800psi. I took 2 shots and noticed that the heavier hammer has minimal effect at this fill pressure.
Now my question is-if I replace the stock spring with a heavier spring (this will obviously open the valve more ) how far can I push it without damaging the valve stem/tophat?
I want to set the power upto around 90fpe. Ammo will be 37,5gr Daystate Rangemasters.
Any help appreciated.

I hit a stock valve that is ported with a 9.4 lb spring all the time. As long as you didn’t port your stem to much nothing is going to happen.
I think it would be just fine. What is the spring rating? I have both heavier hammer, and slightly stronger spring in mine, and the results have been very good. No damage at all.
I did slip an “O” ring behind the top hat to help a little with wasted air caused by hammer bounce. Seems to work well. 🙂
Always wanted to try the Daystate rangemasters, but the cost is far too high here. 😯
How do they shoot for you? What cal. are you shooting them in?

Thanx for the replies, I measured the wire on both springs. The stock spring is 1,6mm and the heavier spring is 1,8mm. There is a reasonable difference in power and I think it will give me the results that I’m looking for.
@Knifemaker-the caliber is .22, I haven’t tested the Daystates so I’m not sure how they’ll do accuracy wise. I’ll test them after work. They’re also expensive here IF you can get them. I have a few left that I’ll use for the comp. After that I’ll go over to 30gr Piledivers.
Thanx again for the help.
