I just picked up a used Winchester model 70 in .270. Much to my delight it shot several different groups of .75"s. Since I don't have a varmint rifle that I can count on yet, I was thinking about using 90, 100, or 110 grain bullets for it. My friend told me that the 90 grainers wouldn't be very accurate and they would also wear out the barrel quicker than 130s or 150s. Is this true, or is he just repeating old wife's tales? The place where I varmint hunt has hundreds of ground squirrels and I usually move from place to place with my CZ-452 but I'm thinking it might be fun for some long range shots. Any advice, suggestions, etc will certainly be welcome!

Rapid firing of max loads is what's hardest on the throat of a barrel. Obvious answer: Don't load to the max, and don't be in a hurry to pull the trigger.
If the twist of your barrel is slow enough for stabilizing a 90-grain bullet, good. You can get quite high velocities without loading "full hot". IOW, a little testing is in order--and as usual, common sense.

.270 Varmints
The .270, My favorite! I've shot it for 30 years and I still love it. I've shot,and in some cases, shot at alot of P.dogs with the .270 and as with all the loads I've used,somewhere between 2950fps. and 3100fps. will give the best accuracy,IMO. Just load 3-5 rounds of a few different powder charges to get that velocity range and see which cloverleafs. Doesn't seem to matter what points I use, from 100- 140 grs. I never shot the 90's, I had read somewhere ,way back, that they would'nt stablize at that velocity. I only shot the thin skinned points once. They come apart at that speed. S.R.

Zip personal experience, but Dad used 110s in his .270 with excellent results.
